Welcome to Apprentice Alf’s blog
This blog is intended to help anyone looking for free and simple software for removing DRM from their Kindle ebooks, stripping DRM from their Adobe Digital Editions ebooks, getting rid of DRM from their Barnes and Noble ebooks, freeing their Kobo ebooks of DRM, deleting the DRM from their Sony eBooks, or decrypting their Fictionwise eReader ebooks.
If you want to find out more about ebooks, DRM and why you will probably want to remove the DRM from your ebooks, see this post: Ebook Formats, DRM and You — A Guide for the Perplexed
If you already know that you want to strip the DRM from your ebooks, you’ve found the right place.
The Tools
To get started on removing DRM from your ebooks, just download the tools archive from one of the links below. Unzip the archive, and start reading.
The latest tools_v6.1.0.zip can be downloaded from

The download link is the grey button. Uncheck the box “Use our download manager and get recommended downloads”
- Do not click on the advert on the right-hand side of the page, even if it says “DOWNLOAD NOW”.
- The download will be a .zip file. If your download is a .exe file do not run it, as you have downloaded the download manager. Make sure that the check box is unchecked
- Make sure Javascript is enabled in your browser.
- No credit card or payment of any kind is required to download the tools.
- If you are worried about the integrity of the tools, listed below is the MD5 checksum.

Getting Help with the Tools
If you have any questions about the tools, ebooks and DRM, check my FAQs post Frequently Asked Questions about the DRM removal tools.
If you have any problems with the current tools, please ask for help in a comment on this post. If you are having a problem with an older version of the tools, please first update to the current version, and see if that solves your problem.
Before commenting here, please check the ReadMe file and the FAQs (see link above).
In any bug report or help request, please include
- which tool was used
- which OS you are using
- where the ebook file came from (device or folder)
- any error messages
- a log of the DRM-removal attempt (see the FAQs on how to get a log).
Anti-Piracy Notice
Please only use this application for gaining full access to your own ebooks for archiving/converson/convenience. De-drmed ebooks should not be uploaded to open servers, torrents, or other methods of mass distribution. No help will be given to people doing such things. Authors, retailers and publishers all need to make a living, so that they can continue to produce books for us to read. Don’t be a parasite.
Origin of the Tools
The tools for removing DRM from ePubs were originally posted at i♥cabbages’ blog. The tools for Kindle/Mobipocket were originally posted at The Dark Reverser’s blog.
They have since been improved by many people, but mostly some_updates, DiapDealer and Apprentice Alf. While there are many sites that redistribute these tools, the most up-to-date versions of the tools are currently released here.
Other Sources
Anyone trying to sell you ebook DRM removal tools for Adobe Adept ePub and PDFs, Barnes & Noble ePubs, Kindle ebooks or eReader ebooks has probably just repackaged (an earlier) version of the tools available here.

All comments were deleted. There were far too many to be useful.
Also, it seems that most of the recent comments asking for help were about the download link, so that one is updated.
— Alf.
AS prev posts were deleted I will repost – please excuse if this was inappropriate–
The download link to 6.08 works but the link to 6.09 does not and diverts when you click download to https://ifilez.org/?lang=en&lp=file4&m=&f=&p=369&pm=5&sid=c6023b9459f51421052f5c46a45cfd052e4f8e74&pctx=11771699397&cus_dlp=true which asks for a credit card
This is now fixed
Hi, the link seems to have been hijacked again. The only ‘download’ is for a .dmg that is some kind of ‘Downloader’ application.
Please ignore my comment – I didn’t see the checkbox on the download page!!!
Guess I should have read the download instructions fully – especially point 3 ! :(
Mark, I think you were right the first time. At least on my Mac, the state of the check box is irrelevant – it delivers only a program which tries to install a downloader tool. If you decline to install the program, it doesn’t bother to download the tools. There’s no way to get them without installing spyware at the moment.
I was able to get the zip file of the tools just now without any other junk. I closed the banner telling me I needed to install a plugin to upload files, unchecked the box for the download manager, and clicked the small grey download button, ignoring the two ads on the page which both said something about downloading.
Works fine for me. As Laura says, uncheck the check box and then click the grey download button.
With OSX, I can get the zip file but it contains an older type of archive which won’t unpack since it’s corrupted. Too bad there isn’t another download link.
There’s a typo in the Info.plist. Look for other comments here about fixing it. Or just use calibre.
link hijacked again?

If that file came from from an E-Ink based kindle, then you just need to enter that Kindle’s serial number in the plugin’s customisation dialog.
Otherwise, install Kindle for PC and download the book through that. Then import that copy. The DeDRM plugin can’t remove DRM without the encryption key, which is different for every book and device. The easiest way to to let the plugin pick up the key from a Kindle for PC installation.
That did it! many thanks.
Excuse me, but it’s this point that has me stumped. I’m trying to convert a Kindle ebook to PDF so I can print some pages, The import fails because deDrm cannot find the key for Kindle for PC and book is imported but conversion fails because ‘book is locked by DRM’.
I followed the steps to install calibre and the deDrm plugin which are outlined below in the blog and set it up as described but the conversion still fails on import, and the plugin apparently failed to pick up the default key for Kindle ebooks. Must I uninstall and re-install the Kindle reader while calibre is running in the background?
The book must have been downloaded through Kindle for PC. Post an import log if you still have problems.
Hi! I’m not very tech savvy and I appreciate how easy is it has been to follow your directions so far, but I need some more help, please. I downloaded the deDRM plug-in for Calibre and it worked great for most of my DRM’d books, but several still had DRM when I tried to convert them. I tried removing them from Calibre and re-loading them several times, but no luck. My OS is Windows 7, 64 bit. I got the file from a folder on my computer. The only error message I saw was calibre telling me I can’t convert my file because it is DRM protected. Here is my log:

Hi Tisa,
It looks like the B&N key you’ve entered isn’t the right one for this book. If some of your other B&N ebooks have decrypted successfully, then perhaps this is one you downloaded a long time ago when the details were different. Download again and try with a fresh copy.
Alternatively, perhaps you just haven’t got the details right. Try entering several variations on your name (case doesn’t matter) and double-check that the number is the default CC number on your B&N account.
The details are right… they have never been changed. I can’t download again, because I stupidly deleted these books after I downloaded them.
This is just a thought – I had something similar happen recently with one of my older Nook Books would not decrypt. I then remembered I had purchased it with a credit card that has since expired. I had deleted that CC key when I got a new card & created a new BN key. I figured it was a long shot as the old card is not even in my BN account anymore but I put the old expired number back in & sure enough it worked! Apparently, the authorization is tied to the card you originally used to purchase the book, which is not necessarily the current card on file in the account.
Oat, you are correct. The DRM for each ebook purchased is tied to your credit number you used to buy the ebook and your name on your BN account. NOT the name on your credit card.
Pat, not Oat. embarrassed smiley here.
Then you’re probably out of luck. You need the name and CC number that were on your account at the time you downloaded the books.
WOOHOO! I forgot that I had Nook for PC and that it stored the B&N books I had bought, even though I had deleted them from the website! Thank you for your help!!!
i downloaded the tools_v6.0.9.zip but when i try to open the DeDRM app (macintosh folder) it says i can’t because it might be damaged or incomplete. help!
There’s a typo in the info.plist. See other comments here on how to fix it. Or just use calibre and the plugin.
I am having an issue with the DRM of my B&N Nook books are not working. These are newer purchases. Here is the debug text:

Try other variations from the names in the various parts of your B&N account, and double-check that the number is the default number at the time you downloaded the books. Currently, it just looks like your haven’t got the right key.
Oh my… you are correct. Wherever the datum came from that you could use the name on your credit card or your address name is false. The CC has my middle initial. I did change to a new credit card for the account. I had created a new key, but used my name with the middle initial. I deleted that key, re-entered without the initial and all is working fine now. Thank you so much! I have spent hours in frustration with this issue! (Probably should have posted sooner, eh?)
Some time ago I set up Calibre with one of your tools and it has worked perfectly. It is not now working. The following are the items I have added to Calibre;

I am using Mac OS X 10 .9.4. I have been downloading ebooks from Kindle store. This is the error message just says book is protected by ddm etc.
My drm log is is empty. When I use DDRN 5.5.5, the log is filled.
I have downloaded tools v6.0.9. I have not been able to unzip the file. I have tried many times and even had a friend using Widows 8 and he too has not been able to unzip the file.
I would appreciate your advice
I had to deselect the option to use their download manager. It is immediately below the gray “Download” button, where it says, “Use our download manager and get recommended downloads”. I was then able to download it okay.
None of those will work with calibre 2.0 and later. Make sure you have downloaded from the link in this post, and that you unchecked the download manager checkbox.

SO- I reinstalled EVERYTHING (kindle, calibre, pluggins…) and it worked. Don’t know what I did wrong the first time, but you can forget this one. Thanks!
Hi, not very tech minded but I downloaded the latest tools and calibre, I followed the instructions but drm was not removed from books I added to calibre, not sure why, any ideas?
You’ll need to give more info. ideally a log of the import process. Instructions on how to get a log are in the FAQs.
If you can’t manage that, at least details on what kind of ebook it is, where it was bought, how you got it onto your computer, and any customisation data your added in the plugin’s customisation dialog.
They are kindle books from amazon web site ; AZW, AZW3 & some Mobi which I downloaded to PC then added to calibre to sort afterwards transfered to my paperwhite via usb. Did not add any customisation as the plugin did not ask for any.
Add your Paperwhite’s serial number in the appropriate part of the plugin’s customisation dialog. Delete the books from calibre and then re-import them.
That worked, thank you.
I have no problem following your instructions to download the alternate files but when I try to download the zip file, I get a page showing “Bayfiles” with no options other than a big orange “Download” button or “Premium download” The “premium download” takes me to “page not found” and the “Download” button gets me all sorts of pop ups and games, etc but no spot to download the file.
Use the link in the post to which this is a comment, not the link in the announcement post.
I’m having an issue with the plugin for calibre. I am currently using a Mac OS 10.9. I have downloaded Calibre for Mac and both the tools_v6.0.9.zip and Other_Tools.zip files. But when I open Calibre and go to add the plugins (using the “Load plugin from file” button) I get an error. InvalidPlugin: The plugin is invalid. It does not contain a top-level _init_.py file.
What do I do to fix this, and I need these plugins to remove the DRM from my Kindle and Nook ebooks?
Thanks.
You are clearly not adding the right file, but exactly what your error is is hard to determine. You’ve either not unzipped the tools_v6.0.9.zip to get the plugin, or you’re also unzipped the plugin. You need to add the zip file that has plugin in the name.
I’ve just downloaded v. 6.0.9 and cannot open DRM Macintosh Application on Snow Leopard (10.6.8). The app’s icon appears with a sort of no-entry sign and I keep getting the message that the app may be corrupted or missing some resources. That’s not the case I think; I’ve re-downloaded, checked md5 and looked inside package contents. The Info.plist looks pretty much the same as version 6.0.8’s (which starts fine). I just can’t get it. TIA for any help.
There’s a typo in the 6.0.9 Mac DeDRM. See other comments for details.
Thank you so much! I fixed it.
Hello Alf, I’m afraid I wasn’t sure how to ask you about an error matter except by clicking Reply.
I bought a book from Amazon – AZW3 format – which I downloaded to my Kindle For PC app on my Vista 32 bit laptop. When I tried to DRM it in Calibre ,the error, “Invalid Start Byte” appears, and the book won’t open. The details are below. I installed the latest tools, though I haven’t updated Calibre for some months. Thank you.
Paul.

Update your calibre and that bug should go away. If you still have problems, post an import log, not a log of trying to view the book in the viewer, which seems to be what that is.
Thank you, Paul Durrant. Updating Calibre to the latest version made the AZW3 book open perfectly!
Paul Moulder.
Hello, I found that the calibre plugin does not remove the drm from some books.
I got some free ones from amazon and calibre fails to convert it.
I get a DRM popup saying it is protected with DRM.
How can i send you the link to the book on amazon so you can download the free book and see for your self?
I wanted to read it on my Kobo but can’t since calibre dedrm plugin wont work nor will epubor.
Please let me know
Thanks
Gren
I just “purchased” two free eBooks from Amazon this morning. I downloaded them to my Mac Kindle app and then added them from the Kindle folder to my Calibre library. No issues. However, I am not a techy/coder…maybe there is something else going on.
Mo
Post an input log. Say how you downloaded the books.
If you see this – I have just put Ubuntu 14.10 on a new netbook. I installed Calibre, and the latest plugin fails because it uses Python 5. Please take a look at this. It occurs between Ubuntu 14.04 which was fine, and 14.10 which is not.
MacAfee is reporting that the downloaded 6.0.9 zip file is infected
If you have the actual 6.0.9 zip file (check the checksum), then it’s a false positive.
Hi I have tried few Times but no succes to remove DRM from my PDF file its still Secured … Any idea ?
Regards
Try adding the default ADE key in the plugin’s customisation dialog (green ‘+’ button).
I just bought some children’s books for the NOOK and two of them are PDF. Is there an “ignoblepdf.py” somewhere?
I would love to know this too. I have some “PagePerfect Nookbooks” that are actually pdfs.
Version 6.0.9 of the standalone Mac app doesn’t seem to work on three different Macs running Lion, Mavericks and Yosemite, if downloaded from the link given: http://www.datafilehost.com/d/979ff0c7 (and I can’t find any other source). The MD5 checksum tallies with the one given here, but on double-clicking the unzipped Mac app file (DeDRM, date-stamp Wednesday, 23 July 2014 02:20), this error message appears: “You can’t open the application DeDRM because it may be damaged or incomplete.”
It has a typo. There are instructions on how to fix the typo in one of the comments here. Otherwise just use calibre and the plugin.

The tools might need an update. I downloaded five books from Amazon that stayed DRM’d despite having tools_v6.0.9 installed.

I just purchased a Kindle book from Amazon and had no issues importing/D-DRMing with Calibre. I did download it to my Kindle library on my Mac first, which I always do… You probably need to post a log so that those way smarter than I can help you figure out what is going on. M
Apprentice Alf, sorry for asking and I’m not sure if it’s posted somewhere and I just weren’t able to find it, but I was wondering if there are any ways to get rid of DRM of manga, magazines and overall books with pics (for Japanese books)? I usually buy them on Kindle, Sony or Booklive, but then again I think Sony’s extension mnh isn’t supported either? When I import the Kindle ones on calibre, it seems to do the trick, but then when you try to open the file, all the images are gone. Books like the Moomin series actually work, keeping both text and images, but only image books like comics are a no go.
Am I mistaken or is there any ongoing project to deal with these issues?
Thank you for your help, and also thanks for everything you’ve done so far!
I’ve been following new comments on here but it seems everyone else deserves a reply except for me…
Did i ask such an horrible and unrelated question? Sorry if I did.
You asked a question that I don’t have an answer to. The only thing I can suggest is trying KindleUnpack on the drm-stripped books and see what that shows. Or ask at MobileRead in the KindelUnpack thread. They can’t help with DRM removal, but perhaps they can help with the book format once the DRM has gone.
My friend just tried it for his Kindle for PC books, but many of them (over half) are still DRM’ed after using, the other half worked fine. I read on another site that others have had this same issue. Any advice? Thank you!
Try the ones that didn’t work again. On Windows, there seems to be a problem when trying to import a large number of books at once.
Otherwise, post a log of one of the import of one of the ones that didn’t work.
Thank you — we had over 300 books (which also makes it impossible to tell which random-looking .azw file corresponds to which book). So we removed them all from Calibre and re-added, this time just doing 8 at a time (instead of all 300+ at once). It worked like a charm — all books appear to be successfully de-drm’ed! Thank you. Also, for what it’s worth, here was part of the log for the initial 300+ add that intermittently failed:

There were several of these errors, mixed in with lots of successful de-DRM’ing messages.
Also, in the process, we tried uninstalling the 64-bit version and installing the 32-bit one, and had the same problem. So re-installed the 64-bit version and added 8 at a time, as described above. Thanks again!

Go into the plugin’s customisation dialog and add in the default ADE key (click the green + button).
I just downloaded the plugins, got them in calibre, put in info(triple checked) for BN DeDRM and it doesn’t work. I even put in keys for old credit cards/possible names. Still no luck. I think BN added something to DRM that is new. PDF DeDRM works fine. Working on Windows 7 and Nook for PC. Please advise. jmhdiver1
See the comments by difflugia for a work-around for the new B&N DRM key.
Hello :
I’ve downloaded the DRM removal tools from both links. All plugins are grey when viewed from Caliber “load plugins” window. i.e not capable of being opened or selected. The Mac application cannot be opened. Mac OS claims the app is damaged.
I use Mac OS X 10,9,5

Customized DeDRM / Barnes & Nobal ebooks / Created unique key, entered user name from account info, shipping info and credit card + credit card number books were purchased and downloaded with.
Older books purchased last year all DRM removed, newer books purchased Calibre will not remove DRM.
Has Barnes & Nobal changed encryption method?

hi caliber works great for removal on my pc but no matter what i do cant get the plugins to work on my laptop. downloded new caliber new plugins nothing working what am i doing wrong LOL
Post an import log. (See FAQs)
Alf I am having a problem with the Calibre Dedrm tool. I am using windows 7 and the latest Calibre. I can remove the drm from AZW3’s BUT I cannot get the AZW’s to remove the Drm. Is there something I am doing wrong? I have placed my Kindle’s serial # where I needed to when I started using this. It still will not remove drm’s from AZW files.
Alf here is the error I am getting with an AZW directly downloaded from Amazon. I am using window 7 SP1, Calibre 2.10. I am not a programmer I just wanted to read this book on my laptop

Dear Alf,
I’ve followed every step on the FAQ page and can’t remove the DRM from a recently purchased EPUB from Nook. All previously purchased Nook Books continue to decrypt with no problem. The one that won’t decrypt was the first I’ve purchased in at least 6 months. I’ve compared the default info in my B&N account with that in my key, have generated multiple possible keys, and have downloaded the book repeatedly. All attempts fail. Here is the debugging log. Any help much appreciated.

B&N is changing the encryption keys so they’re no longer based on your name and credit card. See these comments for a workaround:

See the comment by “Kevin” on 17th November for a detailed solution.

His post seems like it might be helpful for Windows users, but I can’t find the equivalent path on my Mac. Any thoughts?
For OS X users, Kevin’s steps should be replaced with:
3) In Finder, use Go>Go to Folder (or Shift-Command-G) to go directly to Library/Application Support/Barnes & Noble/DesktopReader/logs . (This is the Library folder in your home directory; it doesn’t show up by default in Finder so you need Go to Folder to get there… or use the command line.)
4) Open BNClientLog.txt with TextEdit and find the last line starting with ccHash: ; copy the quoted text on that line.
5-6) In TextEdit, File>New to open a new document window. Paste the key into this window, then save the file on your desktop with a .b64 extension (e.g., bnkey.b64).
11) After clicking Import Existing Keyfiles, locate the bnkey.b64 file you created in step 5 and import that file into DeDRM.
Once you’ve gotten DeDRM working, you can delete the bnkey.b64 file.
Thanks. I’ve tried to follow these steps. However, I can find NO “Barnes & Noble” subfolder in my “Library/Application Support” folder, even though I have the latest versions of both Nook for Mac and Nook Study installed on my machine. Any thoughts?
“, I can find NO “Barnes & Noble” subfolder in my “Library/Application Support” ”
Make sure you look in /Library/Application Support as well as /Users/yourname/Library/Application Support”
Failing that, go to a terminal window and try
find / -name “BNClientLog.txt”
Ignore the “permission denied” messages.
Thanks – I was able to locate the correct file and create a new key, following all the instructions carefully. However, that key was a failure too. I remade and re-imported the key several times, and it failed each time. Here’s the debugging log:

Removing Barnes & Noble DRM with recent (Oct 2014 on) use of cchash code encryption: (Jan 5, 2015) I was able to successfully do this as instructed. Note, I used OS X Yosemite, and was able to download Nook Study, and de-drm a recent purchase. I used TextEdit to make the .b64 file, but this only worked after I changed the preferences in TextEdit to “plain text” for new documents and removed the default “add .txt” when saving files. It took me a while to figure this out (of course).

I have tried to download the 6.09 update, but every time I try – the downloading service you use dropped spam stuff and infected my browsers and computer with virus like software that takes registry access to delete.
Why did you choose something like that ??

Follow the instructions and uncheck the ‘download manager’ checkbox first.
Hi! The download-link for the plugin alternative tools doesn’t work.
Working fine here. Read the instructions.
Thanks for the tools, the process of removing DRM was completely painless (:*
I installed Calibre on my PC so that I can use my Kindle for epub books. I installed the DeDRM_plugin.zip successfully. Under Preferences – Plug -ins – File type plug -ins I can see “DeDRM (6.1.0)”. When I add a book (epub) and try to convert it I get the error message that the book is locked by DRM. I have tried to reinstall, restart the PC, remove and add book(s) again, tried other books, but I get the same result everytime. I add books from Documents – My Digital Editions. The books can be opened in Digital Editions. I don´t know where to find the log file: “On Windows, the DeDRM application creates a log file in your home directory every time it is run. Copy the contents of that (it is a simple text file) and paste it into your comment.”. Where is the home directory? I have Windows 8 and I don´t know where it is. Anyway, I tried the Command Prompt but I don´t think I got that right either since no further output info was added when I added a book in Calibre as you can see:

Please help. I don´t know what to do or what I am doing wrong.
You are running the calibre plugin, not the application, so that bit of info about the log being created in your home directory doesn’t apply. Running calibre by launching from the terminal window is correct. To get an import log after launching calibre from the terminal window, you just have to actually import a book through the interface in the usual way.
I’ve been successfully using your tools with Calibre for years and now it’s not working with B&N books (Hate that they got rid of the download button!) So, I’ve been importing them into Nook for PC, and pulling them into the Calibre-Autoadds folder I’ve also been using for years. DRM is still there on many of the B&N books I’ve purchased recently. Many on gift cards although I try to keep track of the CC number and that’s current in your tool.
Info for you:

======================
Why isn’t it working? Am I doing something wrong after all these years?? :P
Thanks, Alf, for your help and wonderful work!
Happy 2015!
kksdragons
B&N have changed how the key is generated. You should be able to find the new key in the log file of nook Study (or possibly nook for PC). See the help in the B&N section in the plugin customisation dialog in the latest (6.1.0) plugin.
I found ad d/l’d the nook study app, copy/saved the hash and imported it into your DRM app. It worked on a recent book I purchased!!!
Now, will it work on PAST purchases and all the new purchases too? There are a couple I purchased a couple of years ago I couldn’t de-DRM because I forgot the cc I used. :P
Thanks SO MUCH Laura and Paul!
If you download the books now, the new key will work on the newly downloaded files.
See the help link in the plug-in’s customization dialog for B&N ebooks. That will tell you how to find the current key and add it to the plug-in. It’s no longer based on the default credit card, if you’ve changed your B&N account info in the last few months.
It looks like they changed things up again.
There is no ccHash value in the BNClientLog.txt that is created. I’ve tried both Nook for PC and NookStudy.
After some experimentations, it seems like when you log out of Nook Study (using Settings>Account>Sign Out), it deletes the directory that has the NookStudy, and the BNCliet.log too. So don’t log out, and all should be fine.
The download link doesn’t respond at all now. The browser just says that the site takes too long to respond.
Hi,
The link to the latest tools appears to not work today (2015-01-22).
Is there no better way to distribute this, such as SourceForge or Github?
Regards
I second that. Bothe Github and SourceForge are really friendly. And … Although I love wordpress, the high volume of traffic on this site makes it a real pain to use. Both SourceForge and Github have fantastic reporting and comment facilities. SiteOwner – please consider!
Downloading the DRM removal tools from Datafilehost works fine here. I just was able to download with no problem at all.
Alf needs a place where you can upload anonymously.
(The link is working for me right now.)
All these tons of comments are making this page function really slowly and in a very stuttered way. Perhaps you could delete most of the comments where it does not address valid concerns – including this one after you’re done. By the way, perhaps, also, you could reupload the tools yourself to a site that does not have these annoying spyware, etc. I will be doing likewise myself and giving the link to my friends. Thanks for all the effort man!
It worked beautifully for years. In December, I got a new iMac – new 4K – and it stopped working. I’m using it on Barnes & Noble ebooks. I updated calibre. Removed tool and reinstalled latest version – configured it with correct name and credit card information again. Reinstalled Nook app on my computer and made sure it is working on the ebooks. Nothing works. Here’s the printout on the error:

B&N have changed their key generation scheme. See the help in the B&N part of the plugin’s customisation dialog. You’ll need to download and install NOOK Study to get the new key.
I downloaded Nook Study. I removed the books which weren’t working from my hard drive and re-downloaded using Nook Study. I found the cc Hash Response V1 in the log. I copied and made it .64 file and used it as key in Calibre in the plugin. I tried both the entire text after cc Hash Response V1 and just the quote remarks and what was enclosed. I would create the file. Import as key. Close Calibre. Reopen and import books. Nothing works.
I should add, I really appreciate your response. I’m sure there must be something simple I’m missing. I now have 2 log files. One has the cc Hash Response 1V I used. The other is much shorter and has error messages, no request/acceptable responses like the other file. Both update to the same time when I download books using Nook Study. Do I need to remove the Nook app and just leave Nook Study on my computer?
I made it a .b64 file – typo. I used the right extension and the plugin took it.
I downloaded Nook Study and then downloaded my book. Created a new key with my name and CC# and it still doesn’t work. I just can’t decide what I am doing wrong.
The key is not based on your cc# anymore. Read the help file in the B&N part of the plugin’s customization about finding the ccHash from the Nookstudy log.
I dont see anything in the help section about finding the cchash from nook study.
It’s in there if you have version 6.1.0 of the plugin.
I got it. Thank god for google.
Thanks for earlier response which educated me on the new Barnes & Noble encoding, Nook Study, and creating a key from the cc Hash: response. But, I’m still doing something wrong. I’ve tried rebooting. Deleting and reinstalling Nook Study – still not working. I’m sure I have the correct key info – it is consistently the same from one install to the next. I am running newest iMac 4K with newest OS. Calibre updated to newest version with newest tools I could find from link here. Problem is with Barnes & Noble books. Here’s the latest error message – different from before I tried Nook Study and a unique key –

Probably, something is wrong with the b64 files you’re creating. Umm… Try creating and exporting a key file using the plugin, so that you see what they should look like internally. Perhaps that will give a clue as to the problem.
Got it! Thanks. I wasn’t able to find the test key I created using the plugin, but with your hint, I figured it out. My text editor was always storing the key file initially as .rtf and I had to go into Information (Apple system) and change the properties to .b64. The Rich Text Format was messing it up. So, I copied an existing .txt file, deleted all content, and pasted in the key information. Then it would save as a .txt file. I converted that to .b64 and it worked. I really appreciate your help.
Hi there. I am trying to download the DRM remover for Calibre (for Kindle books) and the file is flagged up as malicious by my anti-virus. Could you have a look into it please?
Thanks.
Heather.
As long as you followed the instructions above and got a zip file (not an exe), it’s probably a false positive. You can use the MD5 checksum given above to double-check.
Hi Apprentic Alf. I’ve used your download successfully lots of times. Unfortunately I used the Tools 6.1link on this page and both my computer and my friends brand new computer!&$ were infected with with the istartsurf virus. I’m hoping it wasn’t your download but it might be worth checking. It was a shocker to clean up.
If you downloaded a zip, it wasn’t the tools link.
To Durrant,
I’ve installed 64-bit Calibre and it works! It decrypted the DRM successfully even with this unusually large ebook!! Thanks to your suggestion and thanks to Alf’s amazing tools. Truly grateful!!!!!
Oh, good news. I’m also glad you still got my message, even with the Great Comment Reset. :)
First, please let me thank you profusely for the tools. I’ve used them for years, to make sure my purchases will always be readable. I don’t know if it’s because of tool changes, Calibre changes, or Amazon serial novel DRM changes, but I’m unable to deDRM the Kindle serial novel “Indexing” by Seanan McGuire. I’ve purchased it, the novel is complete, and I can open and read it in the Kindle app, but when I try to import it into Calibre, it looks like Calibre doesn’t know how to open it. Other AZW3’s convert fine.
Actually, I guess the problem was that I hadn’t downloaded that book directly from Amazon so my computer had no key for it.
Hi,
first, thanks you a ton for your work on DRM tools :-)
About file hosting, why not host on Github, or a Dropbox link ? What would be super easy to setup, what do you think ?
I think Alf has said in the past that such services have T&C that don’t allow anonymity.
Seems legit but a bogus identity may work ? Thanks for answering Paul
Here is a very CLEAN link to the 6.0.9 tools. Enjoy!

Just to add, I’m running adobe digital additions 2.0 and just updated to 3.0 but that didn’t make a difference. Also, deleted 2.1 Calibre and reloaded 2.0, just to make sure, but that didn’t work either. The only think I haven’t done is remove all the plugins and then reinstalled them. Just didn’t want to have to redo all the customization for B&N and Kindle.
As I said in reply to another of your comments here:
No, the problems are unrelated. Looking at your log, your problem is that you’re not using the latest 6.0.9 plugin with calibre 2.1. Calibre 2.0 updated to use QT5 instead of QT4, and you MUST update to the 6.0.9 plugin when running calibre 2.0 or later. You should also remove ALL the older DRM removal plugins you currently have installed.
The DeDRM plugin will pick up most, perhaps all, of the customisations you entered in the older individual plugins.
Thank you!!!! removed the plugins, reinstalled with the 6.0.9 pack and works like a charm again. I appreciate the help!
Thanks for the tools. They work fabulously. I have never bought an IBook but notice gift cards on sale at substantial discounts. But I also notice that hte requiem onion site is down and has been since June, and any download links seem to result in the downloading of zip archives which will not open. Do you know if requiem still works to remove drm from IBooks and if so where I can find a working link. Thanks.
I downloaded the latest Tools zip and am getting an error message when I open the mac standalone app “You can’t open the application beauase it may be damaged or incomplete”.
I am running OSX 10.9.4 and Python 2.7.5 and tools 6.0.9 downloaded from datafilehost, btw. I also re-downloaded it a second time and it has the same problem. The new bayfile link you put up today doesn’t seem to work. I just downloaded Tools 6.0.8 and it seems to work so there seems to be something wrong with the current 6.0.9 osx build.
There is. The Info.plist has an extra w where there shouldn’t be one. You can fix it with a text editior, or just keep on using the 6.0.8. As far as I know, the 6.0.9 update was just for the plugin.
Thanks Paul Durrant. It works now.
I too am using OSX 10.9.4. I’m not sure what version of tools I am using but it has stopped working. I had the same issues trying to download tools 6.0.9, I have not been able to unzip the file and get tools v6.0.9. zip.cpgz. I get exactly the same with tools v6.0.8. Did you have any problems unzipping these files and how did you unzip 6.0.8?
Heres the fix – Right click the App > Show Contents –> right click info.plist –> open with –> TextEdit –> search (command+F) for this “w” –> delete the w –> save & close TextEdit –> Run Program.
Opps, I guess wordpress hides anything in between less than & greater than symbols search for this without spaces….. w
That didnt work, sorry about mucking up your space, but I see no edit option. last try – “Less than sign” “slash” “array” “greater than sign” “w” Just delete that W at the end, & all is well.
B&N seems to be using a new epub format that’s throwing the DeDRM plugin off – two of the six books I DL’d today were ignored by the plugin as not being B&N encrypted books, even though they definitely are. Examining the files in 7zip, it seems this new version lacks the rights.xml file in META-INF that all the other files have.
To experiment, I dropped the rights.xml file from one of the files that was successfully de-DRM’d into the bad files and sure enough, the DeDRM plugin realized it was a B&N file but was unable to decrypt. Any advice? I can email you one of the bad epub files if that would help.
Where did you get the EPUBs from? I already discovered the issue with the Nook for Windows 8 app, but B&N hadn’t implemented it in any of their other apps at the time so there was no issue with Windows 7 and Android EPUBs. If they expanded this change to other apps this would become a bigger deal.
Background: This seems to be a new trick from B&N to make it more inconvenient to decrypt their EPUBs. They remove the rights.xml file from the EPUB downloads and instead store the data inside a SQL Database. Copying the data to a blank rights.xml file and then dropping it into the EPUB fixes the issue. So far you have to manually copy the data, but the issue has only been confirmed in the Windows 8 app.
Jay, these files were DL’d directly from the My Library page on B&N’s website. I thought maybe they were corrupt as I occasionally get a bad download, but redownloading solved nothing.
Is that SQL db you mention stored in the epub file or elsewhere? I was surprised to see that this didn’t break compatibility with our older Simple Touch readers, even one running an out of date firmware (1.1.2), so hopefully the change isn’t too radical.
The SQL Database is inside the AppData folder for the Windows 8 app. Can’t remember the exact location off the top of my head, but it’s not encrypted thankfully. But if they’re doing it with the website downloads that’s weird. Have you tried downloading the same book using the Windows 7 app?
As for drastic change, it really isn’t, just a big inconvenience. They basically took the keyhole to the front door of the house and moved it under a rock in the backyard. We have to find the keyhole and put it back into the door in order to use our keys to get in.
I use Windows 8.1 but I go directly to my Nook library (on B&N site) and download the Nook Books from there. Have no problems removing the DRM from those books. Interestingly, I have the Windows 8 Nook app but I don’t see where the Nook Books are stored from it on my PC.
Stop using the Windows 8 nook app and if you have to use the nook app, use the desktop version.
PM is having problems with the EPUBs he’s downloading from the Nook WEBSITE. All I was saying was that the issue is similar to the issue with DeDRMing books from the Windows 8 app and that it might be related. Why are you telling me to stop using the Windows 8 app when I’m not using it? Please read the conversation first before jumping to assumptions and interrupting a technical discussion.
Sorry, I thought you were talking to me.
C:\Users\USERNAME\AppData\Local\Packages\BarnesNoble.Nook_xxxxxxxxxxxxx\LocalState
But as stated before, the books it downloads are missing their rights.xml file which is needed to decrypt them. The information is instead stored inside:
“C:\Users\USERNAME\AppData\Local\Packages\BarnesNoble.Nook_xxxxxxxxxxxxx\LocalState\NookDownloads.db3″
Table= download_doc
Row= BOOK-ID-NUMBER
Column= license
Why would you use the nook app for Windows 8? You can just point your web browser to B&N and download the ePub directly. Just fill in your credit card details in your nook DeDRM settings and you’ll be good to go. You don’t even need the desktop nook app.
Some books, magazines, and comics can’t be downloaded with the PC app. But you can with the Windows 8 app. That’s the interest.
Hmmm, first my epub books from the library in adobe digital editions and now your epub for B&N. My occurred just after the last update to Calibre 2.1. Could this be a common issue?
No, it’s not a common issue. I have no trouble stripping the DRM from ePub in my Digital Editions library. I’m using Calibre 2.1. I don’t know what you’ve done, but you’ve had to have done something if it was working and now it’s not.
I haven’t done anything differently. Exact process as other books. I download the ASCM file, then open it with Adobe digital additions, close additions, open Calibre and import the book. This has done it for the last 2 books. I did uninstall 2.1 and went back to 2.0 but that didn’t change things, so I went back to 2.1.
I did have a newly released eBook download as corrupted and I tried again the next day and it worked fine. It wasn’t a problem on my end. Take a look at the ePub you’ve ended up with. Is it too small to be a correct ePub?
No, the problems are unrelated. Looking at your log, your problem is that you’re not using the latest 6.0.9 plugin with calibre 2.1. Calibre 2.1 updated to use QT5 instead of QT4, and you MUST update to the 6.0.9 plugin for it to worrk. You should also remove ALL the older DRM removal plugins you currently have installed.
Has anyone tried to successfully convert an azw4 format file? I tried and it didn’t work.
You use KindleUnpack to unpack the AZW4 because it’s a PDF in a Mobi wrapper.
here is my log, if anyone can help it would be greatly appreciated, this system used to work fine, I don’t know whot changed

It looks like you’ve changed your Adobe ID or something to do with it. Assuming you were registering ADE with an Adobe ID, your best bet is to wipe ADE from your system completely and reinstall, reregister and redownload.
As a follow-up to yesterday’s post, JWolf seems to have nailed it – today I re-downloaded the two books that were missing the rights.xml file and this time it was present in both, and Calibre decoded them without incident. Not sure what happened yesterday but I guess enough time elapsed that their system regenerated the epubs when I went to download and now everything seems to be alright.
@PM, were these eBooks by any chance new eBooks released that day? The one I downloaded was a new book. It was from HarperCollins.
Very unlikely – they were both on this week’s NYT bestseller list.
I downloaded the tools. Unzipped it but when i go to click on DeDRM.app it says the app is damaged or incomplete and won’t let me open it. I have a mac version 10.9.4. I’ve been struggling with this for 2 weeks. I just want to remove the DRM so I can use Calibre. I have downloaded Python but have no idea how to use it. I’m a newbie to all of this. I have read the “read me” sections of python but don’t even understand what I am reading! PLEASE HELP! I’m trying to remove it from Kindle books.
Install calibre. Install the DeDRM plugin. Drag & drop your books into calibre. You don’t need to install Python.
(The 6.0.9 DeDRM app is damaged and won’t run without a tweak. It’s easier to just use the plugin.)
I have a college ebook that has a lot of pictures in it, specifically some IRS forms. The converter works for most pages, though. When using the adobe digital editions plugin, it seems to reach out on the net to pull those images down. The book is from ecampus.com (I paid for it). You have to log in to ecampus.com through ADE to read the book, something I feel like may be related.
The ADE works correctly when completely offline, so I will toss that idea. It does seem related to embedded objects (which I think are pictures, but I have no way to tell)
Couldn’t get this to work with the latest ActivePython on Linux, had to use 2.7.6 instead and the Kindle key was retrieved successfully.
Yes, it’s written in Python 2.x, as is calibre.
I am trying to download the DeDRM application for Mac. I get the application but when I double click on it, it says: “You can’t open the application “DeDRM” because it may be damaged or incomplete”. Did I miss a step?
Same here.
Unfortunately, DeDRM 6.0.9 for Mac is damaged. The Info.plist has an extra w where there shouldn’t be one. it’s easy to spot in a text editor, (e.g. TextWrangler), so it’s easy to fix it by hand. But otherwise just use the 6.0.8 version if you can find it, as there was no real difference between them. The 6.0.9 update seems to have been just for calibre 2.x compatibility.
I am having this problem. I am looking at the Info.plist but I do not see what “w” I should remove. Can you be more specific? I also tried version 6.0.8 but it does not run at all on my mac. os x 10.9.4. Any help is much appreciated.
As far as I recall it’s at the end of one of the lines after the >. But if you have 6.0.8 then there’s no need. 6.0.8 does run on 10.9.4 but you need to set your security settings to allow it to run. Or you could try right-clicking on it and selecting ‘open’, which might then ask for authorisation to run this unknown, unsigned application.
The extra ‘w’ is on line 19.
The line reads “w” but should read “” (all without the quotes)
Darn, WordPress has eaten some text that look like HTML tags. (They’re XML tags.)
Pretend the [ and ] are angle brackets: line 19 reads “[/array]w” but should read “[/array]”.
Thank you very much for your work!
Came across your site when trying to figure out how to remove a DRM from a book an author friend send me via email. I use Calibre and he said he has no issues with the book. It’s in .azw I want to convert to epub to read on my phone. but nothing will remove the DRM. Here is what is showing from the CMD line. I’m sure I’ve done something wrong, as usually that is my case.

Amazon’s the only one who can add DRM to azw files, so if it has DRM it must have passed through Amazon’s servers. Ask your author friend to send you a copy of his book before it’s gone through Amazon.
The calibre plugin chokes on a Digital Editions PDF obtained from a .acsm file I purchased (ADE version 4.0.98786).

The plugin will work, but you need to go to the customisation dialog and tell it to add the default ade key to its list of keys.
Hi,
I’m new to Calibre and DeDRM, but have done everything as told. The ebook has been bought by me, but I need citations for a blog. Adobe DE 3.0 does not provide me the Copy&Paste feature, so I decided to decrypt it. However, it doesn’t succeed. Here’s the result of debugmode. It is likely a coding error:

You need to go to the customisation dialog and tell it to add the default ade key to its list of keys.
I cannot find ‘Customisation’.
Ah, I found it and it now works. What I’ve done to add the key:
Preferences > Advanced=Plugins > Check: Show only user installed plugins > Doubleclick File type plugins > Doubleclick ‘DeDRM etc’ > Customize plugin > Adobe Digital Editions ebooks > press the + button > Press OK (if ‘default_key’ is okay for you > Close > Ok > Apply > Close
I guess it is caused by my laptop being Windows 8.1?
No, it’s because you’ve only tried to remove DRM from PDFs so far. It seems that the bit of the plugin that handles ePubs will go and try to get the default key if it’s not there, but not the PDF section, so you need to do it manually.
Okay, good info for others too. I saw another person here with the same issue.
Me too.
Without finding this thread I would be using Epub Adobe ePuB&PDR DRM Removal tool, which found the file and removed the DRM with a single click! I tried again with Calibre-DeDRM6.0.9 because I think it a better solution if it worked. Maybe a FAQ with the above explanatory post and a statement that “The DeDRM6.0.9 plug in ends up in File type plugs-ins of Calibre Ver2.6.0″ would have made several hours into several minutes for me. BTW Calibre Ver2.6.0 seems to have a different interface to the https://apprenticealf.wordpress.com/2012/09/10/calibre-plugins-the-simplest-option-for-removing-most-ebook-drm/ post.
Thankyou very much for your excellent plugin.
Hello. I have just installed calibre v.2.2 and the latest deDRM plugin, but my imported Kindle books are still DRM blocked. I’m not sure if I do it right, but I followed the instructions carefully and have read the FAQ. I downloaded all the books with Kindle for PC, and I imported them by dragging them from that directory. But they are not decrypted in Calibre, so I am unable to read them there. What am I doing wrong?
I was successful on my desktop computer. It runs Win7, whereas my laptop runs Win8.
Anyway, thank you very much for this awesome tool! Finally I can use my study books how study books are supposed to be used, with a proper reader and stylus :)
I’ve run into a similar problem using Calibre on Mac and the latest deDRM plugin. The stand-alone app for Mac was damaged. I have Windows 8 installed through Parallels, but no luck there either. Am now getting a copy of Windows 7 to see if I have any luck, like your, trying it that way. It seems a bit elaborate to remove DRM from a file, but this has become a personal quest now :-)
If you’re on an Intel-based Mac you’ll be much better of using calibre and the plugin than messing around with Parallels.
Running into a problem with the obok script. I’m totally clueless concerning Python and programming, but managed to set up everything to start running nicely until, after it lists about a third of the boks in my kepub folder it gives me this error message:
File “obok.py”, line 198, in
print “%d: %s” % (i, volumekeys[key][“title”])
File “C:\Python27\lib\encodings\cp850.py”, line 12, in encode
return codecs.charmap_encode(input,errors,encoding_map)
UnicodeEncodeError: ‘charmap’ codec can’t encode character u’\u2013′ in position
44: character maps to
A bit of googling gives me the impression that this is a common problem in Python 2.7, but this is what the obok script is for – so how to fix it?
Oh, at the end of the error message it says “undefined” in code brackets
It sounds like a character encoding problem. Look for a later version of the script?
I’m using the script from the Other Tools package in the latest version offered here. After your reply I saw that my PyCrypto version was out of date, but with the latest version of that I still get precisely the same error.
PyCrypto isn’t related to this, as you’ve discovered.
It looks like you’ve got a book in your Kobo database that has some characters in the title that your terminal window can’t display. Python’s a bit tricky here, I think. I can find plenty of web pages telling how *not* to handle this, but not much telling *how* to handle it :-(
Can you set your terminal window to use something better than CP850? This is a character set encoding; I’m not sure if Windows (?) lets you configure this at all in the Command Prompt, but if you can make it use something like Unicode or UTF-8 that will probably help.
Something else that might work is setting the PYTHONIOENCODING environment variable to UTF-8 before running the obok script. The script will output something weird instead of your book title, but it should carry on working.
On Windows do this:
SET PYTHONIOENCODING=UTF-8
and in the same window run the obok.py script as you do normally.
Thanks a lot. I did a bit of googling myself and found a lot of stuff about how it’s Windows related and a lot of workarounds that go way over my head. So your help is much appreciated. It’s not that urgent right now and I’ve got lots of things on my plate, but when I get around to fiddling about with it a bit more, I’ll report back.
Where did you find the ‘Other Tools’ package.

did i miss something along the way?
thanks in advance,
Try running it by double0clicking and going into the preferences and seeing if it shows the default Kindle key being present. I thought it created it automatically, but perhaps not.
on the DeDRM Configuration window, i select Kindle for Mac ebooks and i get a window that says
Current Kindle for Mac key files:
Local Kindle Key.k41.
To add extra key files (.k4i), click the Add… button.
searching for a .k4i file gives me: ‘~/Library/Preferences/com.apprenticealf.dedrm/Local Kindle Key.k4i’ which contains:
[~] cat ‘Library/Preferences/com.apprenticealf.dedrm/Local Kindle Key.k4i’
{“IDString”: “39393939393939393939”, “kindle.account.tokens”: “48”, “kindle.cookie.item”: “41”, “UserName”: “746f6d”}[~]
How interesting. In that case, delete that file (Local Kindle Key.k4i) and see if it re-creates it with the same info. If it does, I’d try doing the unregister/uninstall/wipe preferences&application support/reinstall/reregister/redownload route with Kindle for Mac and see if that fixes things (obvioiusly also delete the LocalKindkeKey again as well).
that worked! i deleted the file (well moved it), restarted DeDRM and it created a new and much different k4i file.
thank you!
Just downloaded DeDRM v6.0.9 and am running Calibre v2.2 on a Win 7 computer. I’m trying to customize with the serial # of my newest Kindle, and every time I click on ‘customize plugin’, I get an error message. calibre, version 2.2.0

Have done the usual uninstall/reinstall and restart Calibre routine, but continue to get the error. It worked fine with the prior version of the plugin and earlier versions of Calibre up until today (no changes made to the system). I removed the old version of the plugin and installed the newest version, but continue to get the error.
Thank you for all your work on this tool!
I suspect that you may have an older version of the plugins installed as well. Make sure that DeDRM 6.0.9 is the only version.
Thank you. I ended up doing a search on C drive and deleting anything & everything with “DeDRM” in it, then re-installing, and now the customization is working as expected.
I have been downloading ebooks from Amazon into “Kindle for PC” and then into Calibre with plugin to read on my Sony Reader.
Recently purchased books from Amazon now go into “Kindle Cloud Reader” and I can’t figure out how to get them onto my Sony Reader.
Can anyone help please. If I am out of order posting this request on here I apologise.
If your Kindle for PC installation is still registered with your Amazon account, on the web pages at Amazon for your Kindle Library, there should be an option to ‘send to Kindle for PC’. Alternatively, in Kindle for PC, you should be able to see the books in your library and select them for download. If your can’t get the books into Kindle for PC (or onto an E-Ink based KIndle), these tools can’t help you.
Paul, Thanks for your help which is much apprfeciated. Problem solved. Cheers.
Hours ago I used alf’s plugin to process the books I bought recently, all handled well but one .azw4 book, it is over 400MB.
Calibre spends minutes to “diagnose” this book then displays in the library just like all the other books, I can see the cover, title, author, etc..
But when I want to view it or convert it, it displayed “locked”.
So my question is, alf’s tool can’t handle such a large size book? The tool doesn’t tell me fail to unlock it, but the truth is the book is still locked.
I know how to use this tool and have used it for years, so I am sure it’s not my operation error.
Thank you
Try using the KindleUnpack plugin. azw4 are really PDFs wrapped in an Amazon wrapper. KindleUnpack will extract the PDF. If KindleUnpack says it’s still locked, it’s probably a memory error (because of the big size), in which case try installing the 64-bit version of calibre (assuming you have a 64-bit version of Windows installed).
Doesn’t help. The AZW4 book is locked and the “Unpack AZW4″ option is greyed out. I guess the large file size causes memory error when decode the book, I am using the latest version of Calibre 64-bit and I have 8 GB RAM on this PC. Maybe the file size is just too large.
You can check the error by importing it when in debug mode (see the FAQs on how to get a log). With 8GB you should have enough free memory to remove DRM from a 400MB file.
I add the book and when I try to convert it I get a DRM message I don’t know what i’m doing wrong

Hi there, I am a newbie at all of this I recently was given a kobo for my birthday and there are a few books that I would like to read but they are only available on kindl, so this software would be perfect…, I have downloaded the new calibire and wanted to download the plugin for it link that you provided but when I went to run the file it had the exe file I guess it’s the sites software you said not to download. The page only has the big orange button saying download which on previous posts you had said not to click and I couldn’t find another way to get the zipped file. Is there something I am missing? Thanks
Did you UNCHECK the ‘Use our download manager and get recommended downloads” check box before clicking the ‘DOWNLOAD’ button (grey on my system) that’s immediately below the ‘Size: 1.73 MB’ text?

Unfortunately, the download link on that web page takes one to a trashy video site.
I did dig around and found this web page, so I was able to download the “tools v6.0.9.zip” file. I just thought you might like to fix the link on the other web page.

Since that part of the log isn’t from the plugin at all, it’s impossible to tell what your problem is.
At a guess, I’d say that something was trying to convert a date and is getting fouled up due to internationalisation issues – German dates are formatted differently to American ones, etc.
But it is impossible to diagnose this any further without something like a stack trace. Trying to force the language/locale to English *might* work.
Strange, Calibre Plug-in doesn’t work on my DRM’d PDF Files, yet, the stand alone app does ?
Anyone have any idea why ?
Go to the plugin customisation dialog and add in the default ADE key. While the plugin does this automatically for ePubs, it doesn’t if all you ever decrypt is PDFs.
Thanks for the reply, but, I did add the adekey file, all I get is the same DRM’d file when pasting it inside Calibre, but, the stand alone configured with the same adekey file does the job, very strange….
OK, I deleted the key I had, and created a default key and all is well, thanks to all who replied….
Can you guys figure out how to remove the DRM of Yuzu (Barnes and Nobles) textbooks? They’re copyrighted using Adobe’s DRM but idk the Adobe ID that they create after buying the book.

Hello
I have downloaded the latest Version of Calibre (2.3.0),
afterwards I tried to download the latest Plugin to remove DRM (AZW-File) – 6.0.9
I got a data–folder named “Version 6.0-9″ but it obviously containend the Plug-in-Version 6.0.8
(from July 23 2014).
With this configuration I tried to convert a AZW-Book (see below), but it failed.
I wonder, what was wrong
Can you provide help ??

http://www.publishersweekly.com/pw/by-topic/digital/content-and-e-books/article/64003-harpercollins-adds-digital-watermarks-to-e-books.html
According to this article Harper Collins is adding a digital watermark as added DRM protection. Just wondering if anyone has encountered this new type of protection yet & if there is a work around in the works?
I have some books containing a digital watermark and it is a line of text stating that I (my name) bought that book, but it is unencripted. I do not know whether that is what they intend.
Who cares? Digital watermarks don’t affect your use of the ebook. You can still convert it to your favourite format and read it on your favourite device.
Trying to convert a pdf file to a mobi, but is still DRM-ed. Here is the log. Thank you in advance.

The ‘Successfully decrypted” is false. It hasn’t recognised the DRM on the ePub, and so hasn’t been able to remove the DRM. Where’s the book from?

Go into the plugin’s customisation dialog and add the default ADE key by clicking on the green + sign.
Trying to convert an azw3 file into epub using the Calibre plugin, but i get the error message “Cannot convert – This book is locked by DRM”. Have checked the FAQ, seems to be a key problem but don’t know how to fix it. Debug below. Grateful for any help!

That book (from the name of the file) doesn’t seem to have come from Kindle for Mac. If it’s from an E-Ink based kindle, you need to enter the Kindle’s serial number in the customisation dialog. Otherwise you need to download through Kindle for Mac and import that copy.
Hello. I used the plugin without any issue on windows but now I moved to linux and the key can not be found. I followed the steps to install K4P through Wine after adding the extra component but it still won’t decrypt my book.

To be able to get the key needed from the Wine installation, you must install Python (& I think Pycrypto too) under your wine installation. I think there are instructions on this in the readme.
Hello Paul.
Yes it works. I misread the readme file and thought you had these were refering to other DRM types.
Thank you and sorry for the trouble.
Edit to last post: It has been working fine till this one, all the python stuff is installed in the wine folder. This is the 1st one I have done since the v2 of Calibre and the 1st with 6.09
If you’re Fingerhut, your log says otherwise:
wine: cannot find L”C:\\windows\\system32\\python.exe”
If you’re not Fingerhut, your post has probably got automoderated
It looks like it was moderated. I had posted a log which had an error relating to wine saving in my ~/.config/calibre etc folder. Basically it didn’t save the key file so the undrm didn’t happen.

The folder exists but I: is already /home/hairybiker
I think the problem is the IDString ‘0’. I seem to remember some comments about the disk ID in wine sometimes being 0 by default sometimes, which messes up the decryption. You’ll need to give the disk ID some non-zero value, unregister, uninstall and reinstall Kindle for PC, and re-register it. And re-download your books. There might be something in the readme about this.

A very different error. Last time it couldn’t decrypt the key file. This time it could decrypt the key file, but it couldn’t write it out.
For some reason I don’t understand it seems to think that your wine installation has an l: drive instead of a C: drive. Or something like that.
IOError: [Errno 2] No such file or directory: u’I:\\home\\hairybiker\\.config\\calibre\\plugins\\DeDRM\\libraryfiles\\winekeysdir’
is the vital bit of the log. Clearly it’s something to do with your configuration of wine, but we’ve now got beyond my competance.
Oh. I’ve just re-read both logs again, and you’re right it is the same error. It’s something weird in your wine config. Sorry I didn’t spot it earlier. I don’t know how to fix that.
As I said I: points to my home folder. I think it should be I:\\.config\\calibre\\plugins\\DeDRM\\libraryfiles\\winekeysdir not I:\\home\\hairybiker\\.config\\calibre\\plugins\\DeDRM\\libraryfiles\\winekeysdir.
If it wants the full path then it should be z: which is my root folder.
It does exist (the folder) and as I said it used to work with Calibre <2 and 6.07 which was the one I was using before the updates.
Is there anyway to patch this to use Z not I?
I really don’t know. I’ve never used the Linux/wine in ernest, I only once set one up following the readme. And in that case I think I certainly only had a c: drive.
If you’re Linuxy enough to be setting up wine in a complex manner, I think it’ll be up to you to work out how to configure things to work with it.
Alternatively, you could set up a simple, separate wine system. Or perhaps try running the key generation manually under wine and then import the key manually into your linux calibre.
This is a simple wine install, I didn’t add any drives to it, I only have 2 programs installed in it, with the addition of the python stuff needed for this. I can try recreating a new wine install and see if it fixes it.
How would I go about generating and adding the key manually?
Bearing in mind that I haven’t done this….
You’d need to open a command line window and enter the commands from the log:
WINEPREFIX=”/home/hairybiker/.wine
wine python.exe “/home/hairybiker/.config/calibre/plugins/DeDRM/libraryfiles/kindlekey.py” “/home/hairybiker/.config/calibre/plugins/DeDRM/libraryfiles/winekeysdir”
Although, obviously(?), changing the last parameter to be a directory path that works.
OK manually running it generated 2 key files and allowed me to import the book. Still get the error but at least the book is readable now.
I imported Kindle .azw to Calibre (plug in already installed). However, when I converted it to PDF, got this error. Please help. Thanks.

DRM gets removed on import. You need to post the import log, not the conversion log.
Hi Paul, how do I locate the “import log”? I couldn’t find it. Thanks.
Hi Paul, Update: I located the “Import Log”. Please read below. It’s about missing key. But that’s the part I don’t understand even reading the blog. I tried to entered “Default_key” but that did not work. Please advise. Thanks.

How odd. Where did you get the book file from? If it was downloaded to your Kindle for Mac installation I would have expected the DRM removal to have worked.
However, if you copied the book from some other device, that would be why it didn’t work. Try downloading through Kindle for Mac and importing that copy of the book.
Hi Paul, I think I got it to work now. I had to de-register, uninstalled Kindle, and re-installed. Now Calibre removes DRM without problem. However, one question: I started Calibre in Debug mode to get the import log file, but this time it did not give me Import Log. Is that because it removed DRM successfully so it has no import log file?
If you start in debug mode from a terminal/command window, then the log will appear in that window. If it doesn’t, you may have mis-typed the debug command. A log will still be written to standard output on a successful decryption (since at the time the first bit of the log is written, it’s not known whether the decryption will be successful or not).
Is it possible to use a calibre plugin to remove DRM from KePub books? I know something called obok is supposed to work, but have no idea how to use it. I’ve followed a link to pastebin, but don’t have the knowledge or understanding to proceed.
Have learnt how to do it. Many thanks to a fellow MR member.
And how? Do you have a link to explanation?
I’d really like to know, too.
See post by “Helpful Helper” lower down in comments
I did see it. Thanks.
I had a bit of trouble getting this to work on ubuntu 14.04 with wine. I followed the instructions exactly and installed kindle for pc in wine. It was a fresh clean install so the default prefix was used. I finally had to install python via winetricks and manually path to python with wine and run the command to get this keys manually like this
wine ~/.wine/drive_c/Python26/python.exe “~/.config/calibre/plugins/DeDRM/libraryfiles/kindlekey.py” “~/.config/calibre/plugins/DeDRM/libraryfiles/winekeysdir”
I’m not sure why wine wasn’t finding python but it wasn’t.
After I did this everything works. Thanks for the script and I hope this helps someone else.
Hi!
After having utilized this software for years now it doesn’t seem to work anymore for me in the previous version. Calibre now lets me know it could not de-DRM the Kindle book.
When I download the latest version here http://tinyurl.com/8q3t59l Immediately my Emsisoft Anti-Malware puts it in quarantine. When I have it restored to Downloads and click on it Windows 8.1 says it can’t work on this pc and deletes it!
(If I could attach anything to this post I would make some photographs of what appears on my screen and show it.)
The link I posted by mistake was leading to Alf’s site. My intent was to post the link to this one: http://1phads.com/afu.php?
zoneid=5900
With apologies.
It works fine, but -as said- my AV mistakes the file for a Trojan, and Windows 8.1 deletes it. At least on my notebook.
It would be nice to be able to enjoy it again, as reading Kindle books on my Onyx Boox M92 (9.7″) e-ink is easier on the eyes than on my notebook screen.
Although I can live with that, so ultimately it’s no biggie. ; )
Why not download 6.0.9 from the link given in the post this is a comment to?
Thank you. No AV warnings this time.
I unchecked downloading the downloader add on, but still I got this:
B and N Download Helper
As well as:
DRM Key Scipts
Kindle for Android Patches
Kobo
Rocket ebooks
Scuolabook DRM
Since I only use this software for Kindle books, what should I use as plugins for Calibre?
You should download the “latest tools_v6.0.9.zip” not the (slightly mislabeled) “latest plugin alternative tools”. That is, you need the first download link, not the second.
Thanks again.
I now see:
DeDRM Calibre Plugin
DeDRM Macintosh Application\
DeDRM Windows Application
ReadMeFirst
I guess I need the Calibre one and maybe the Windows one (not using a Mac). Is that right? Or do I only need the Calibre one?
I suggest that reading the ReadMeFirst file might answer your questions as well, but if you’re using calibre, you only need the plugin one. The Windows and Macintosh applications are for those not using calibre.
Great, thank you. : )
I get this message from Calibre when I try to install the DeDRM plugin:
ERROR: Unhandled exception
InvalidPlugin The plugin in u’C:/Users/User/
Downloads/tools_v6.0.9 zip’ is invalid.
It does not contain a top-level__init.__.py file
I try to installonly the plugin for Calibre. If I open that file I see a long list of items. But I close that and then only click on DeDRM_plugin.
I wonder if it might have something to do with Windows 8.1. I already had to reformat it after installing SpeedFan -for which Windows 8.1 gave the message that it wouldn’t run on this pc. Since I never had a problem with it on XP and 7, I tried in safe mode. That crashed Windows 8.1.
Luckily I have a Windows 8.1 disk,and a system backup and incremental ones saved on an external drive with the help of Backupper, a freebie.
tools_v6.0.9.zip is not the plugin. You need to unzip tools_v6.0.9.zip to obtain (among other files) the DeDRM_plugin.zip file. It’s that file you need to install in calibre.

That log shows a successful removal of DRM. What makes you think it didn’t work?
(BTW, you probably shouldn’t have the Inept Epub plugin installed as well as the DeDRM plugin, not that that affects Kindle books.)
Hey guys, I’m using OSX 10.6 on my old mac. Are there older versions of drm removal tool software available that works with calibre?
Thanks
Stefan
What version of calibre are you using? I can’t remember which version dropped support for 10.6.
If you can’t get the plugin to work, the stand-alone AppleScript should work, so you could remove the drm using that and then import into calibre.
The Problem is that I can`t install the latest tools 6.0.9 or 6.0.8 because of my old fashioned OSx 10.6.8. Is there anywhere an older version of the tool available?
6.0.8 installed awhile ago in mac 10.6.8, without any issues, haven’t tried 6.0.9 ?
6.0.9 should work with calibre 1.48 which is the last version supporting Mac OS 10.6.

The obok scripts have been turned into a calibre plugin. If you have kobo books to decrypt that aren’t standard ADE ePubs, this should help. It works with the Mac and Windows kobo desktop program, adding a button to the calibre toolbar which gives you a list of all the books available for decryption and import.
The file in this link IS the plugin. Don’t unzip it before adding it to calibre!
http://www.datafilehost.com/d/858189ea
I expect Alf will add this plugin to the standard tools download sometime.
Thank you so much. I figured this had probably been posted some time in the past and that I had just missed it. I appreciate your help!
Thanks a lot for the plugin. Is there a particular reason for not doing any compression in the unencrypted epub zip file? Standalone Obok used to do it and I think it makes sense to make the files smaller if there’s no technical problem with it.
It creates the new file using zout = zipfile.ZipFile(outname, “w”, zipfile.ZIP_DEFLATED) which should be compressed.
Nope, the plugin uses this line in action.py :
zout = zipfile.ZipFile(fileout.name, “w”)
You’re right, I was reading the obok.py script’s main code included in the plugin, not spotting the book generation algorithm was mostly copy/pasted into action.py. (And dubiously relicensed as GPLv3, which the previous obok code was *not* under.)
Funny how you want to enforce copyright on a piece of code designed to remove DRM.
The GPL is a license. Copyright – which is a different thing – still rests with all the people who’ve contributed to obok,
There have been some version updates to the obok Calibre plugin (decrypts Kobo kepub format and outputs epub) Current is v3.0.7
You’ll find it on Nates The Digital Reader: http://the-digital-reader.com/2014/09/25/download-kobo-ebooks-including-ones-wont-allow/#.VEGjJVdyGdl
Follow ‘Rosie’s’ comments for update and other info.
Hoping that Alf will pick up the obok Calibre plugin and add it as an optional extra to his existing suite.
Thanks, I tried now with 3.07 but I have the same problems with 3.07 and 3.03, it always tells me that it cannot decrypt the files. Looking into the log generated with calibre in debug mode, I see messages like: Decryption failed, trying next key. .. .Bad XML: …..
Is this something that is related to encodings, too?
Post a log of what happens when you try to add a book with obok. You must have the kobo desktop app installed and working on the same machine/user account as your calibre installation.
Hi Paul, hi Minx,
sorry for the incomplete information, here are mor details:
– books are visibile in Kobo Desktop
– books are listed when clicking on the Obok button

Does that help?
And you are using Kobo Desktop? Not the Windows 8 app? I don’t know if obok would even find the books if you were, but I thought I’d ask.
I *think* I am using the Kobo Desktop … I have “/Users/norbert/Local Settings/Kobo/Kobo Desktop Edition” directory containing the books etc.
Is there a Win8 App – is this separate from Kobo Desktop App? How can I check that?
Anyway, something else:
Now I am trying to do the same on my sweet home Linux system without booting into Windows8. What I did is:
– unpack the obok plugin
– made some trivial changes, actually only set KoboLibrary.kobodir to the path to my windows location of Kobo.sqlite
– changed the MAC address detection to be done on mac and linux the same way (all macs are the same on Win and Linux, HW adress is not changed)
And thus I got the obok script running without any problems. With adding a few debug statements I see:
$ python obok-linux.py
1: AZUMI
2: And the Mountains Echoed
3: Hotel Iris
4: I Hate to Leave This Beautiful Place
…..
Convert book number… 2

So something is wrong.
I have now unpacked the obok plugin and edited the
Norbert as a suggestion could you uninstall Kobo Desktop and install it again. See if obok works differently then.
Bingo!!! That solved the problem. Strange strange. Thanks a lot.
I see you got everything sorted –yeah! I just wanted to answer that you’d know if you were using the Win8 app. It’s a full screen Metro style app that you get from the Windows Store. No idea where or how it stores the books. I don’t think any of the DRM removal tools work with any of the Win8 apps.
Hi Laura, thanks. Oh this Metro style, I am trying to ban it from all units, so yes, definitely the original app.
BTW, does anyone have an idea whether the *same* decryption mechanism works *on* the Kobo itself?
I mean, if in the obok.py script you send the koboroot to the mounted device .kobo dir, then you have the sqlite database, the encrypted kepubs in the dir kepub. The only thing you need to find out is the MAC address of the unit, which is easy to get.
So that should work, too, and would get us all rid of the requirement to have anything installed (like Kobo Desktop or so).
Any ideas?
As Paul says please post a log. But I’m curious do the book/s that you want obok to import into Calibre already exist in your Kobo Desktop for PC? Can you see these books in Kobo Desktop for PC? Obok searches through the Kobo Desktop files and prints them.

To T Nguyen:
Go to the customisation dialog of the plugin and create the default ADE key (green +) before deleting the book from calibre and reimporting.
Could someone please reply with DETAILED instructions on setting up the obok plugin, with or without calibre? It seems like all the comments here regarding that are just a tease. MR forums makes it difficult to help by not allowing discussion for DRM removal.
First step should be where to find the script. The only link I found shows an executable, not a script so I wonder if it is correct. If it is indeed an executable that works in calibre, How do we get it to work in calibre?
It is very frustrating to see comments that only say “I got it to work!”
I downloaded it from the link in a comment here by “Helpful Helper”. I loaded the downloaded zip into calibre as a plugin, and then I got an icon on the task bar (after a restart of calibre). Clicking on the icon got me a list of the books in my Kobo desktop application for import, and I just selected one.
Joey, I’m no expert but I can tell you what I did to install the Calibre plugin – hopefully, I remember all the steps.
First I opened my Kobo Desktop app and let it sync so that all my Kobo books would be available on my computer. I don’t use the app much but I think the plugin uses the library from the app to get the book files. All of the Kobo books I have were also available as downloadable epubs (I don’t have any kepub-only books to test with), but I think that when they’re synced to the Kobo desktop app they’re all automatically downloaded as kepubs. On my computer the books are stored in C:\Users\Sue\AppData\Local\Kobo\Kobo Desktop Edition\kepub.
I clicked on the link in Helpful Helper’s post which brought me to a download screen. I don’t have any ad blockers installed so there were two download buttons showing and a checked box that said to use a download manager. I UNCHECKED the manager box and then clicked on the smaller of the download boxes (it was on the left side) and saved the obok_plugin.zip to my computer.
Then I opened Calibre (I have version 2.3) and clicked on Preferences. On the next screen I clicked on Plugins under Advanced. On the next screen I clicked on Load plugin from file and navigated to where I had stored the zip file and selected it. After it installed (it appears under the User Interface Action plugins) I closed and reopened Calibre and the obok icon appeared at the top right of my Calbre screen.
To use it, I click on the new obok icon and it gives me a list of book files to choose from. I believe it is every book in my Kobo desktop library but it doesn’t appear to be in any particular order so I have to scroll through the list to find the book I want. I select a book and it gets the file, strips off the DRM, converts it to epub and adds it to Calibre.
I hope someone will correct this if I got anything wrong.
I agree with everything you said and did. Thank you for being so detailed and helpful so others can understand and follow.

How to retrieve the ADE KEY?. I usually drag’n drop the ebook into calibre, and that’s all.
Run calibre. Preferences Menu. Change calibre behaviour. Plugins. Show only user installed plugins. File Type Plugins. DeDRM plugin. Customize plugin button. Adobe Digital Editions button. Green + button.
That should add the default ADE key to the plugin’s preferences. The delete the book in question from calibre and re-import it. If that doesn’t work, post another log.

Where’s the books from?
I clicked on the download link in the post that said 6.09 Posted — the top post on this blog. That link took me to what looked like a download locations. I don’t believe it had anything about using download manager. But when I clicked on the download button, it took me to register for some game called Wizard 101. I did it twice, thinking I had done something wrong but both times i wound up in the same place. I think the download link needs to be fixed. I eventually found another place to do the download — not sure how I got there but it worked.
Thanks for the great tools!

http://nyupress.org/books/9781479880782/
A good test subject, as it only costs $1.99
Latest plugin is installed in Calibre 2.4.0 (latest), and Kindle serial number has been properly entered in the plug-in’s settings.
Cannot import from either Kindle device or from saved copy as downloaded from Amazon to PC disk.
I get the “Cannot Convert” error message from Calibre.
Double-check the serial number is right. It must be an E-Ink based Kindle (e.g. Paperwhite). Post a log of the import (see FAQs).

Have successfully decrypted Barnes and Noble Nook books in the past, but today, seem to be stymied.
Using Windows 7, Calibre version 2.4 (the latest), DeDRM 6.0.9. Recently updated default credit card number at B&N (old card was compromised), name on account hasn’t changed. Name and CC number in the plug-in are correct; I triple-checked. Downloaded ebook TODAY via Nook for PC. Still will not decrypt. Debug file pasted below. Any enlightenment? Thanks.

In addition to the above, I just added back in two different old credit card numbers, as well as three different old gift card numbers, which between them should cover any and all ebook purchases I ever made at Barnes and Noble. Now with a total of 6 B&N key files. After adding them, I hit OK, close, apply and close all in proper sequence. Re-imported the ebook file. STILL will not decrypt.
Since I downloaded the book to the computer today and the first key file I tried was for the current credit card on file at Barnes & Noble, that would appear to disprove the “credit card on file at time of download” theory.
Further suggestions?
The number will definitely be the default CC# on file at time of download. Use that number, but try variations of your name — all the versions in your account. Just because you only changed the your number, B&N could still have decided to use a different name with the new number.
I haven’t even gotten to the dialogue part. I’m trying to D-DRM my Nook books, without success. I’ve put in my default credit card number, all kinds of variations of my name and nothing is happening. Do you know wheter it is only the default card that needs to be entered, or do I have to enter expired cards from my past BN book purchases?
Holly,
Use the name on your BN account. Exactly. Then you must use the cc # you purchased the book with or the default cc# at the the time of purchase if you used a gift card.
You name on the credit card is irrelavent. Use the name on the BN account.
I had the same issue re decrypting of BN books after I changed cc. The solution is to create a key for the expired credit card you previously had in your BN account when you bought the book that will not decrypt. I’ve had a BN account for quite some time & there have been 3 different cc associated with my account. I created a new BN key each time I changed cards but kept the old ones as well. Neither of the expired cards are in the account anymore but I no longer have problems with decrypting.
You need the default CC# at the time of download of the book, along with a name. Th name can be any of your names on your account – the main Account, the shipping address, the billing address or the CC# name. Just try keys with all the different variations present in your account.
Hi gues im trying to dedrm my .pdf
im running
Windows 7 x64
python 2.78
Pythoncrypto 2.10
DeDRM 6.0.9
When i drag my pdf over the .bat file i get FAILED
heres what it says:
Processung:…. ****.pdf FAILED
Complete: Successes: 0, Failures: 1
To add my previous post…
i do not have any adobe reader or whatsoever installed
The only pdf reader i have on my computer is foxit reader.
Then you’ll need to install ADE. The tools get the key from the ADE prefs/settings, so without ADE the tools can’t get the decryption key. You’ll also need to run the key script to get the ADE key and supply that to the decryption script.
Thanx for replaying!
I have now installed ADE, i ran the keyscript and got the ADE key.
So i tried to dedrm my .pdf again and i got the same error as earlier.
OK, silly question time: You can now read this PDF with your installed Adobe Digital Editions?
Not silly at all :), i never tried opening it with ADE, i just did that and ADE says “Unable to add document” “Errors were encountered in this item”
When i try to open same document in FOXIT READER it says, “This document is encrypted by an unsupported security handler”
Hi, I’m trying to remove the drm from a .pdf book file downloaded with Adobe Digital Editions using the calibre plugin. File gets imported, but the drm is not removed – I just get a blank pdf. This process worked fine in the past (ie when I installed the most recent calibre and plugin back in July 2014) but doesn’t work today (when I reinstalled OSX on my computer and had to reinstall everything else too). I have no ‘old settings’ to interfere with anything so I’m not sure why it doesn’t work.
Calibre 2.4.0
Plugin 6.0.9
OSX 10.9.4
Adobe Digital Editions 4.0
Use of the DeDRM tool removes the DRM just fine (after the already noted “w” removal from info.plist) but I was hoping to have a calibre option.
I tried to create a calibre log as outlined in the FAQ but calibre 2.4.0 doesn’t have the “command line” checkbox needed? Any help is appreciated, thanks!
You need to go to the plugin’s customisation dialog and add the default ADE key to its list of keys by clicking the green + button.
The name on my account at B&N has not changed, but just as an experiment, I went in and retyped my first and last names, no spaces or anything, and clicked “save changes.” I also deleted the default credit card and re-added it as if it were new, being very careful with my typing, and made it the new default. Then I went in and redid my billing address and linked it to the credit card.
Back over to Nook for PC, where I removed the book from local storage (or whatever they call it) and then hit “download” again. Up pops a message saying to please verify the default payment method in my account. Gaaaaah! Signed out of my account on the web, signed out of the account in Nook for PC, went to sign back in again, and still getting the “verify payment method” message.
They are not making it easy….
Well, you’ll have to work through all that, but I didn’t actually ask you to do any of that, only to try variations of your name in your B&N account – account name, billing address name, shipping address name, CC name, and any other version or copy of your name they might have. Including any honorific like Mr or Miss.
Once you get it all sorted, things should work again.
No, you didn’t ask me to do all that… but since my name has not actually changed, either in real life nor on my online account(s) I thought I’d try re-entering it all, for apparent lack of anything better to do. Unless B&N unilaterally changed something in my name at their end, there is no other version of my name. In an effort to rule out every possibility, I did go through ALL of the possibilities; account name, billing address name and shipping address name, made sure they were all the same, no spaces at the beginning or end of either first or last name, and saved all the changes, and one more time deleted and re-entered the credit card information, again making sure there were no leading or trailing spaces in the name fields, set the card as the default, and linked it to the billing and/or shipping address I had just redone.
It was then that I went to try to re-download the book in Nook for PC so the latest download would presumably include the “changes” I made in my account. I am still waiting to see if I will be able to get past the “please verify your billing” messages and finally re-download it.
Meanwhile… is there, perhaps, some common variation on someone’s name that they might be using at their end? For instance, if my name were Mary Smith, what might they do to vary that? Smith Mary? SmithMary? MarySmith? Might they stick a Miss or Ms or Mrs on the front even if I didn’t? Have other folks experienced a unilateral name change or variation at Barnes & Noble’s end, and if so, what form did that take?
In all the reports of problems with this, the name has always eventually turned out to be one of the names entered at the B&N site, and the number is the default CC# at time of download.
I have never heard of B&N changing the form of the name in any way, just that which (account/billing/CC, etc) name they use is unpredictable.
Have you tried with a book that you’ve had success with previously? (That is, re-downloading it and seeing if you can remove the DRM from the new copy.)
If all that fails, post another log.
I’m trying to DeDRM a book I just purchased at Barnes & Noble to work on a 3rd Generation Kindle. I am using the most up-to-date Calibre and DeDRM plugin on a 64-bit Windows 7 box. I have also tried on a Vista box but gave up on that one. I entered my Kindle serial number as well as my B&N sign on and CC#. I also created a B&N key with my full name and CC#. I created the 64bit keys from the plug-in set-up page too. Nothing seems to be working. Here is the debug. Someone please help! Thank You!

I’ve been wrangling this epub for hours. I think I’m ready to give up. :(
Thanks for the great blog. I’m with you: Down with DRM!
I should add that it’s a book given to me by a friend in both pdf and epub format. Neither would open w the password she gave me, and none of the DRM apps I tried worked (reported both formats as broken files). Went through a bunch of them on both Mac (OS 10.6.8) and Windows 7. I’m completely stymied.
If it’s a book your friend has made, get a DRM-free copy from your friend. If it’s not, it’s not your copy and you won’t get any help from me in stripping the DRM!
Hi,
Not sure if this is Calibre or the DeDRM plugin with the issue. I downloaded a graphic novel to my Kindle. It will import, but Calibre shows all blank squares with question marks. I have googled for .azw6 files and calibre, and all topics are flagged as most people use DeDRM. I am not sure what to do to make a graphic novel appear in the library. It will also not convert the azw3 file it creates upon adding to the Library. Is this just something the plugin/Calibre can’t handle yet? The .azw6 is located in the book folder with .sdr, while the .azw3 is in the documents folder.
Information that might help: Win 7 32bit, DeDRM 6.0.9, Calibre 2.4, using Kindle Paperwhite 2nd gen, via USB. Normal azw3 imports and to .mobi conversion work perfect. Just this 1 book that is a graphic novel is the issue. Only file difference I can find is the .azw6 being the largest file size indicating it contains the images/pages not the actual .azw3.
Any help making it import / convert is appreciated.
See this post at mobileread:
http://www.mobileread.com/forums/showthread.php?p=2853403#post2853403
I suggest you contact the KindleUnpack developers (KevinH especially) through MobileRead. As far as I know, at present there’s nothing that handles azw6.
Thank you Paul! I will try and follow.
Hi
I’m not a technical net native at all. Can someone help me by solving my problems.
I’m aimimg at converting some books from Kindle für PC (.azw) to EBuB.
As Long as I used my old maschine under OS Windows XP it worked fine using Calibre and the ReDRM Plugin for Calibre
Now I’m working with Windows 8 and there are several problems
Having installed the latest Calibre-version 2.4.0 and adding the plugin-version 6.0.8 several books still had DRM when I tried to convert them. I tried removing them from Calibre and re-loading them several times, but no luck.
Now I thought, this might be due to the older verion of the plugin,. But I cannot succed in installing the latest Version 6.0.9.
For this – my first – problem the debug is als follows:

HI everybody
the first problem is solved. I obviously just didn’t realise, that the download of Version 6.0.9 had to be actively unzipped.
Now the integration of the plugin into Calibre went smoothly
The second problem will probably be solved by going to the DeDRM prefs and adding in the default ADE key manually (it doesn’t auto-generate it for PDFs)
Whoops. Answered the wrong questions. If you’re still having problems importing from Kindle for PC, note that the tools DO NOT work with the Windows 8 Kindle for PC app. You must download and use the “Windows 7″ Kindle for PC application from Amazon’s web site, which works fine on Windows 8.
Tried importing a DRMed PDF, won’t open outside of Adobe Digital Editions even after installing plugins.

Good morning. Having followed your directions I’ve tried converting a Kindle book (AZW) to an HTMLZ file without success. Here’s my debug file. Any insights? Thank you for your time!

I am trying to open a Kindle AZW3 file downloaded with Kindle for PC (Windows 7 Version) in Calibre 64-bit 2.4 with DeDRM 6.0.9, and the following message disappears. I tried everything – reinstalling Kindle for PC, adding a new default_key for te DeDRM Plugin and trying it also on a newly set up Windows 7 64 Laptop (with freshly installed Calibre, Kindle for PC and DeDRM). I don’t know what to do anymore. Any help?

Any help appreciated!
My guess is that your user name has a non-ASCII character in it, and that seems to upset the plugin. Try creating a user account without any non-ASCII characters in it.
I’ve hit a bit of a brick wall, and can’t seem to figure out the solution. I was gifted a few Barnes and Noble gift cards, but primarily like to keep things DRM-free on my kindle paperwhite. I purchased an DRM’d ebook from B&N, loaded the latest DeDRM plugin in calibre, filled in every combination of name, username, first only, last only, etc in the plugin config for Barnes and Noble, but nothing seems to want to let this book deDrm and decompress.
One thing i’ve noticed, is that really off keys tend to give “Key is Null” errors, while the one I expect to work (First Last, CC#) gives a Error while Decompressing in zlib.
Help :-(

Either error means that the decryption key is not correct. You could try changing ALL the instances of your name in your B&N account to be identical, make sure there’s only one CC# entered in your account, and then re-download the book and try a key using that unique name and number.
Talking with B&N’s live chat, apparently they’ve changed the DRM to prevent sideloading. No more First Last, CC to unlock.
Well. I was going to say that of course they haven’t changed things, but I’ve just tried myself (downloading through NOOK Study for Mac) and they do indeed seem to have changed things. Books I already have downloaded I can decrypt, but a newly bought and downloaded book won’t.
But it’s late. Perhaps I’m making an obvious error. I’ll try again tomorrow.
Well I guess if I purchased DRMed ePubs, I’ll purchase them from KoboBooks not B&N.
I’ve had another go, taking my own advice to make sure all the names in my B&N account are the same, and that I haven’t made a mistake with a number. Still no joy on newly downloaded ebooks. It looks like B&N have indeed done something different. Perhaps that’s why they no longer allow direct downloads.
Unless someone else has had success with current B&N purchases?
I was curious so I just bought a ninety-nine cent book from bn.com. I used Nook Study to download it then found the file with explorer and “opened with” the viewer app. It failed with the message that it was DRM locked. I added it to Calibre and it did get unlocked and I was able to read and convert it.
The book is from the US B&N store, published by Kensington, title “Mission to Murder”. Looking at my Calibre plugins, my B&N customization shows as
firstname space lastname underscore last4digitsCC
which agrees with my account settings on B&N. My actual CC (AMEX) has a middle initial but that doesn’t show in the settings.
It seems that at some time a plugin update must have changed the customization format (or at least what it shows)? Looking at my old notes from 2012, I see that I actually entered the customization as
firstname space lastname comma full15digitCC
Thanks! So it seems to if you have it set up already then it still works. But setting up with a new name/CC# may not be possible.
Or, of course, I’ve made a mistake. But I’m pretty used to how these tools work.
Concerning the problems with removing the DRM from B&N ebooks. I’m still using the v6.0.8 stand-alone modules on a Windows 8.1 machine.
I just purchased a ebook with DRM from B&N, downloaded it via “Nook For PC” (which I found still works) and was able to remove the DRM via the DeDRM_Drop_Target app.
I have purchased several books from BN & had no problem removing the DRM, in fact I just did a free one just a few minutes ago as a test. It seems most of the people who are having problems have recently changed a CC or opened a new account (within the past months or so). I did change a CC in August but have not had any problems with either new or old purchases DL through Nook for PC. As to BN keys I have all of my old CC numbers entered. So, the problem may have something to do with the timing of the change made to the account. If they changed the DRM scheme it seems strange old people with recent account changes would be affected, but I guess anything is possible. I am still using a very old set of Tools. (6.01), have not upgraded Calibre beyond 1.48. & still using ADE 2. Even though I have Win 8.1 I still have the older versions of the Kindle & Nook for PC apps. My philosophy is – if it is not broke, don’t fix it. Keeping my fingers crossed!
Add me to list for BN issues – card number changed a week or so ago. Now I can’t dedrm new purchases, but old ones still work.
Tried with DeDRM for windows app, newest Calibre + Tools 6.0.9 and older Calibre/Tools.
Hi, I wanted to get rid of the drm of a book I got from amazon. Unfortunately it didn’t work. I’m using Calibre Portable on Windows 7. I got the following message from the debug mode:

I can’t see any output there from the DeDRM plugin. Make sure it’s installed.
I have used these plugins through countless versions of both DDRM and of Calibre without trouble until yesterday. I encountered a book which I could -only- get through Google Books as an Adobe Digital Editions PDF, a combination I had never encountered before.
I downloaded the acsm file, installed Digital Editions 4.0 on my Windows 8.1 system and opened the book successfully there.
I update Calibre to 2.4 (and then this morning to 2.5, and updated DDRM to 6.09 to deal with the updated versions issue.
Then, I attempted to import the PDF from documents\my digital editions and ended up with an encrypted pdf. After running debug I saw in the log “DeDRM v6.0.9: Ultimately failed to decrypt after 0.4 seconds.” as have many others.
Reading the instructions kindly supplied in these comments, I went into configure the plugin, hit the green plus, accepted default-keys as a name and closed. I then deleted the book and re-imported and all was well.
This is a compliment to the programmers and the community, and I thank you. However, I offer the following two thoughts.
The documentation for the plugin at the post https://apprenticealf.wordpress.com/2012/09/10/calibre-plugins-the-simplest-option-for-removing-most-ebook-drm/ says:
…..On Macintosh and Windows systems no customisation is required for ebooks from Kindle for Mac/PC
…..or Adobe Digital Editions (ADE), provided that calibre is run on the same computer and user account
…..as the installation of Kindle for Mac/PC or ADE to which the books were downloaded.
…..The default key is found and stored in the preferences automatically.
The thing is, of course, it wasn’t. This seems likely to be because I have an old much-updated calibre installation and an old much-updated ddrm installation. It seems like one of two things ought to change:
*** Since hitting the green plus -worked- and the system found and saved the decryption keys on its own… it would seem that the most reasonable thing would be that if the system get to the “Ultimately failed to decrypt” stage, it ought to assume that the keys weren’t there because the ADE installation is new and it hadn’t known to go get them before, even tho there is already a set of preferences saved for the plugin.
or
*** Modify the instructions on the installation post to say
…..The default key should be found and stored in the preferences automatically, but if it somehow isn’t, go to plugins, select the DDRM plugin, configure it, select Adobe, and hit the green plus.
While I found that by searching through these comments (thank you again) I also note that this is a repetitive request. I also note that this answer is NOT in the FAQ document, so I adding it there is option 3. The FAQ has instructions for dealing with B&N and Kindle keys not getting imported, but there is no FAQ for this problem of not automatically getting the default key for ADE.
— I strongly suspect that this is a meta-effect of having previously used the plugin on many kinds of material but only installing ADE yesterday, and I suspect that it counts as a bug that can be addressed, but if not, modifying the instructions or adding an FAQ should do the job.
— Finally, I note that the HELP link in the ADE Keys screen (Managing Adobe Digital Editions Keys) does not contain any mention of using the green plus to go get the default key. That would have been nice too. Until I found that answer here (thank you again) I had tried using the “import existing key files” button, but that, of course, accomplished nothing. It never occured to me that hitting + might find the default, I mistakenly thought that if I hit + I would need to know all sorts of specific stuff about ADE keys and i knew I didn’t want to mess with that.
Anyway, that’s a long comment about an obscure and uncommon problem, but this thing works so well that at this point _alL_ the probems are obscure and uncommon. Thanks again to the community.

I beleive the plugin does work as described in the ReadMe and FAQs for ePubs. Unfortunately, it seems that the same is not true when importing PDFs. Of course, if you have previously imported an ePub, then PDF decryption will work without manual intervention.
Perhaps Alf will fix it in 6.1 or 7.0. I have no idea how tricky it would be to add it in.
I’ve used Calibre on two previously owned computers (now long gone) and both had the DeDrm plugins added successfully. I just added Calibre to both my Dell Desktop-2009, which is running Windows 7, and my HP Pavilion Laptop-2011, which is runnning Windows 8. I have tried to install the DeDrm tools on both and have been unsuccessful. In both cases, I follow the same path and it’s hanging up in both cases at the same place. I’m not real techie, so I probably need the kindergarten version of how to fix this. Here is the path I’m taking within Calibre and the error responses I’m getting I’ll highlight in bold.

Here’s where it goes wrong. The Downloads folder comes up and I highlight DeDRM_plugin and then hit Open.
The window asking: Are you sure? comes up and I hit: Yes.
This is what I get then:

Then I ask for details and this is what I get:

BadZipfile: File is not a zip file
At first I thought maybe it wasn’t compatible with Windows 8, but the same thing happens on the desktop on Windows 7. I turned off my AdBlock just to see if that makes a difference and it doesn’t. The DeDRM zipfile I got was sent to me by a friend after I told her I was having trouble making the one downloaded from this site work. I occasionally got a message that the zipfile was empty. Anyway, nothing is behaving like it did when I did it before on the computers that are now in cyber heaven and I’d love someone to tell me what I’m doing wrong.
Sorry, no idea. The log doesn’t give the name of the file that you’re trying to add. Perhaps you’re not expanding the zip file you’ve downloaded? Although that usually gives a different error. Perhaps you haven’t unchecked the download manager checkbox, and you don’t actually have the tools archive at all?
Where do I uncheck the download manager? I just tried to redownload the tools from and AVG won’t let me. Should I just tell it to ignor the threat?
ADDENDUM: I got it to load! I went into the unzipped file and clicked on the calibre plugin and then it loaded fine. Second time through, AVG didn’t come up. Thanks much.
Plain fantastic, superb job
I have always used these tools with Calibre on a Windows machine. However, I just made the move to a Mac. Now I am having trouble. I have Calibre downloaded and running just fine. I have followed the DRM removal instructions and added the application to my dock. That is where the problems start. When I try to double click it to set me preferences I get the following message:
“You can’t open the application “DeDRM” becuase it may be damaged or incomplete.”
I deleted the first file I downloaded and unzipped. I tried it again and still get the same message.
Any thoughts on what I should do?
Just use the plugin in calibre instead. There’s a typo in one of the files of the DeDRM Mac application – see other comments here if you want to have a go at fixing it yourself.
I’m upgrading to a new computer. I don’t have any issues on my old computer (OS X 10.9.5, Calibre 0.9.38 and DeDRM 6.0.7). However, when installed on my new computer (same OS, Calibre and DeDRM), the same epub imports but keeps the DRM. I’ve authorized Adobe on my new computer and de-authorized on the old one. I don’t see any differences that would cause the DRM-removal to not work on the new computer. I ran in debug mode and got this in the log:

How odd. I’d try with a fresh copy of the 6.0.9 plugin first.
Umm…. you haven’t ever run any “slimming” or “shrinking” software on your old computer, the stuff that strips out the ‘wrong’ architecture from fat binaries have you?
I am have trouble removing the DRM from my B/N Ebooks. It has been working for years but I recently had to enter a new CC as the default in the B/N account and ever since the DRM removal has not worked. All B/N names are the same for Shipping, Billing and account names. In the plugin I still have the old CC information listed along with the new one. Below is the Log output. I say some similar enters on other comments, Any New Ideas?

I finally got everything working a few weeks ago as far as DeDRM’ing my B&N eBooks. Put an ePub Reader on my Windows 8 Phone, and was able to read my books on my phone (which is really all I’m after). Bought a new book today, and B&N no longer has a download button in My Library on their site. So I can’t get a file in order to DeDRM! I hook up my Nook HD to the PC and of course the directory containing books appears empty. How can I get the file of the eBook so I can decrypt it? Someone mentioned they were able to download via Nook Study? Is that something I can download? I can’t believe how many hours I’ve spent on this, only to be foiled by B & N again!
Yes! You can download Nook Study here: https://yuzu.com/nsdownload. Nook Study keeps a local copy of your books. I was then able to open with Calibre and DeDRM it and I can now open it with the reader of my choice on any of my devices. :)
Hello,
I can’t seem to remove DRM a nook epub through calibre on windows 7. It downloads just fine through Nook for PC. All my name/CC info is correct and it is the same CC I used to buy the book (as well as the default card).
I’ve removed DRM from nook books in the past just fine (as recently as June 2014) but having no luck with this one. I’m starting to think BN has changed something.
I’m wondering the same thing. I just purchased a new Nook book over the weekend. Both name and cc are correct, but the calibre plugin won’t remove the DRM. I’ll try to post my log file tomorrow.
Looks like I’m in the same boat! I am having a problem stripping 2 DRM books (6 of 8 were dedrmed just fine). I’m using Windows 7 HP v6.1 (build 7601:sp1), MD5 (tools_v6.0.9.zip), added into Calibre v2.5 from my Nook. I got the “book locked by DRM” msg when I tried to open it. I checked for older versions of the plugin. Any help would be appreciated.

Removing DRM from B&N books is not working for me (ADE books worked just fine!). Name and cc information is definitely correct.
I tried to get the log information, but the instructions don’t match the menu options:
“On Macintosh only you must first run calibre, open Preferences, open Miscellaneous, and click on the “Install command line tools” button.” — however, there is no “Install command line tools” under Miscellaneous.
I’m running Calibre 2.5.0 on Mac OS 10.9.5.
It does look like B&N have changed their DRM since they turned off downloads. Existing setups work for now, but new ones don’t.
I think that calibre now automatically installs the command line tools on Mac.
It appears that not all new purchases have a changed DRM. I had 1 pre-order available today work for de-drm, 1 ebook I purchased today worked, but another pre-order was locked. I did my downloads from the website using Greasemonkey script. I was able to download the locked ebook in the Nook desktop and was able to de-drm that file. I’m going to check my 1E nook to see if that file will de-drm. But I don’t expect either of those options to work long-term.
The command-line tools are installed inside the application bundle on the Mac now.
The top of http://manual.calibre-ebook.com/cli/cli-index.html describes this, but a bit incorrectly. An example command-line tool is /Applications/calibre.app/Contents/MacOS/ebook-convert.
I get an error message when I type the command in Terminal on the Mac.
But I just now did the process using my virtual Windows machine. Here is the log:

You don’t seem to have entered any of your B&N account details into the plugin’s preferences. It certainly won’t work with your name and CC# being entered. But I should also say that it seems that B&N have changed their DRM scheme for new accounts/accounts with new details.
Thanks for your answer, but I don’t quite follow. I did enter the requested information (name & cc) for B&N in the customize dialog just as described in the instructions so a key is created. What other preferences do you mean?
The use of the key doesn’t show in your log. When decoding a B&N ePub, the tool outputs a line saying which key is being tried, like this:
DeDRM v6.0.9: Trying Encryption key Paul_XXXX
I couldn’t see any such line in your log, so I thought you hadn’t entered any keys. Are you sure you entered them in the B&N ePub section, and not the eReader section? Or perhaps you have more than one copy of calibre installed?
Sorry, I don’t know what happened the first time. The key was no longer there so I tried it again with the same information and here is the log file:

Yes, that looks like you have a key in there. Unfortunately, it looks like B&N have changed their DRM scheme for new/changed accounts. You could try any variations on your name in your account, but I don’t hold out much hope. Perhaps someone is working on the new scheme.
As my name is pretty straight forward (no middle name), I also don’t think this will help. It must be due to the change in DRM scheme. Well, no more B&N books for me.
Yep. See:
https://github.com/kovidgoyal/calibre/commit/0e8bc340eba322d498dc9b7aaa91488abbd43957
Actually that was corrected by a later commit: https://github.com/kovidgoyal/calibre/commit/a9dab307fb4ad7784bcd4b9a41944e15bbd51d97
Hello,
I have several e-books I purchased and downloaded (before Adobe launched Digital Editions), so they are drm protected pdf files that I cannot even open anymore, not even with Digital Editions. The removal software won’t work unless I can at least open the book. Any ideas?
These tools won’t help. There may be commercial PDF cracking software available that can help, but I don’t really know anything about that. There were several PDF DRM schemes before Adobe’s Adept DRM that Adobe Digital Editions uses.
Long time listener, first time caller. Thank you for all your hard work on the tools.
I’m trying to import a Barnes & Noble book in .epub format but the DRM isn’t getting stripped.
I’m running Windows 7, and using the Barnes and Noble Desktop Reader 2.5.6.9575. The file I’m importing is one I downloaded just today. The file I’m using is located in:
C:\Users\\My Documents\My Barnes & Noble eBooks\<My Email Address\
I've got the latest plugins. I'm 100% sure I'm using the credit card number I used to buy the book a couple days ago, and I'm equally sure that credit card was the only one associated with my Barnes & Noble account at the instant I downloaded the epub file with the desktop reader.
I've tried generating keys with my name as:
Firstname Lastname (as shown on my B&N shipping address)
Firstname M Lastname (as shown on my credit card)
Firstname M. Lastname (period after the M)
flastname@mydomain.org (email address used with B&N)

Kindle Voyage/
The new Kindle Voyage looks interesting. Any issues with the deDRM tools???
It’s been out long enough that I would have expected to see reports of problems by now if there were any. So I expect that just entering the Kindle’s serial number will be all that you need to do.
Just got my Voyage today and I can confirm that all I needed to do was to enter the serial number into the DeDRM app and into the Calibre plug-in. Works fine! Also it works well with Calibre which was another worry I had going in. So far I really like the Voyage and have not had any issues with the yellow/blue screen reported in their Forums even with the backlight all the way up. So, guess they addressed that problem.
Did Amazon change their encryption? Calibre 2.5, Tools 6.09, e-ink serial’s in the right place, I can open all MOBI and AZW3 books prior to today’s purchases. (Slackware, Linux, book came from a folder, not device.)

DRMError: Bought Book
That’s a conversion log, not an import log. If the book file didn’t come from a device (and wasn’t downloaded for USB transfer to a device) then the serial numbers you’ve entered won’t have any effect. Most likely, if you’re on Linux, there was some difficulty getting the key from your wine installation. But post the import log and we’ll see.
I always download for transfer via USB.
Then if you download for transfer via USB to an EInk based Kindle, you just need to have that Kindle’s serial number in the plugin’s preferences. If you can’t get it to work, post an IMPORT log.
http://pastebin.com/1QcdNagt
Double-check the serial number (0/O and 1/I are easy to confuse). Which model Kindle?
Serial’s correct. E-ink. Only started happening when I upgraded versions of Calibre to 2.5.
WINE regression? I’m using 1.7.28 now. Switching versions of that isn’t an option.
On a whim, I recreated the WINE prefix I used for it. Now works. I’m assuming it’s just cruft…
If changes to WINE fixed your problem, then you must have been downloading these books through Kindle for PC under WINE, NOT downloading them using the “for transfer via USB” (to your EInk Kindle) option.
Hello,
I installed Calibre V2.5.0, downloaded the latest plugin tools_v6.0.9.zip, and attempted to install the plugin following the directions on this website. I never receive the security warning and do not see the deDRM plugin when I search for user installed plugins. I’m using windows 7.
Thanks
Then it sounds like you didn’t install the plugin. You don’t mention unzipping the tools zip. You do need to unzip the tools zip to get access to the plugin (which is also a zip, but you must not unzip the plugin itself).
I cannot download “tools_v6.0.9.zip”. I only got “get.php.html”
You might have some kind of ‘download accelerator’ installed. The simplest thing is to try with a different browser.
Thank you. I stopped downloadthemall and got it.
I got a fault:

You need to unzip the tools zip file to get to the plugin.
hi sorry to bother you but i was hopping for some advice im using the tools for calibre and it works great i have many LIT files i tryed to use LITconvert that was mentioned but cant due to the fact you need the MS reader to start the conversion however MS reader can only be used upto windows XP. Any way to add a similar tool to calibre ?
If you no longer have a machine on which you can read your .lit ebooks, I think you have lost access to them. I beleive that Microsoft stopped support for Microsoft Reader in August 2012. You’re at least two years late in removing the DRM.
But I’m not an expert on .lit. It may be that you could still a copy of Microsoft Reader and get access back. If you can do that, Convert Lit is what you need to remove the DRM. I very much doubt that any attempt will be made to add .LIT DRM removal to the DeDRM plugin.
You should be able to convert your LIT files using ABC Amber Lit converter. This is available from download.cnet.com and does not require an installed copy of reader in order to convert the files. It will do bulk converts. It does not do DRM removal. If you need that, you will need Convert Lit which is available at convertlit dot com. However, it requires a running and activated copy of reader. :-( To use it, you may need to use VirtualBox to set up a virtual xp machine to run and activate reader, and then run convert lit.
If your docs aren’t DRMed, then the free ABC Amber lit converter will work for you.
However… be very very careful when installing that, since it comes with a big pile of cr*p ware which you must -carefully- opt out of when installing.
-_ Rick
Calibre will also convert LIT files if they don’t have DRM.
Tried to install Calibre and your tools on a new Win8.1 PC. HAd ADE and K4PC istalled before Calibre and the Plugin. Got this output in debug-mode:

That’s a very odd fresh installation that also has the old k4mobidedrm plugin installed.
However, there seems to be some problem with finding the K4PC key. I’d try completely uninstalling K4PC (including and prefs and registry) and re-installing and re-registering. Also, note that you must use the K4PC for Win 7, not the version available from the Windows 8 app store. And do delete that old k4mobidedrm plugin.
I installed the calibre dedrm plugin but I cannot convert the kindle books. I’m using windows 8 and I have in the same PC and user the kindlePC app.
thanks
The tools don’t work with the Windows 8 Kindle for PC 8. Download and use the “Windows 7″ Kindle for PC application from Amazon’s web site. It works fine with Windows 8.
So amazon is now selling books that wont work with the Windows 7 Kindle PC application, so I thought I would grab the file off of my eink reader but I cant get it to work. I know I have the S/N correct as i cut and paste it from the amazon website and then deleted the spaces. Any ideas?

DRM removal happens on import, not conversion. Delete the book from your calibre database and reimport it. If that doesn’t work, post a log of the import process.
Thank you, I knew it had to be some bonehead misunderstanding on my part.
Thanks Paul, I have disinstalled the windows 8 kindle PC, installed the windows 7 version, but it is still not working. How can I see the log file of the import process?

If you haven’t changed any details in your B&N account recently, it might just be that you haven’t got the right form of name. But if you have made changes recently (last month or so) then you’re currently out of luck. It looks like B&N changed the key generation algorithm when they stopped allowing downloads from their web site, and the tools don’t work any more.
my account is new, so I’d be in the Out Of Luck category. But I read somewhere that when I download the book from them, in the reader, then in order to work offline the reader generates the key and stores it locally in a DB in plain text. That’d be an alternative way to make it work. Any ideas where?
Someone mentioned earlier this year that B&N were sometimes omitting the rights.xml file from the ePub, and instead storing it in an sql database. This isn’t the same as the decryption key, more the lock that the key fits.
But I don’t know what they’ve changed this time. Perhaps if anyone finds out they’ll post a comment here.
Given that that’s the case, can some kind of disclaimer be posted about the state of the Barnes and Noble part of the DRM stripping plugin/app? That it could only be use for files downloaded before the change (and give an approximate date of when we think that happened) if you’ve made any changes to your account (added a new card &c)
I tried adding a B&N epub to calibre using the plugin. First I discovered the plugin was old and updated it. Then I deleted keys and made sure everything was in sync with my account. Then I deleted and redownloaded the ebook file. Then I reinstalled Python and pycrypto, remade my keys, deleted and redownloaded the ebooks. I tried adding the epub to calibre at multiple stages of the process, and it always showed a new entry, but with no cover picture, and claiming there was still DRM when I tried opening it in the calibre viewer.
Here’s the log of my last attempt:

I guess I didn’t look at the comments well enough before posting. Just noticed the previous one about updated B&N DRM. Any news on an updated decrypt for this?
I am still running Win 8 with ADE 2 & Calibre 1.48. I also still use the Kindle PC app for Win 7 & the Nook for PC App for Win 7. I am using an older set of Tools but everything is working fine & my motto is “if it’s not broke, don’t fix it”. Unfortunately, I am now getting a MS nag screen about every 4 hrs about upgrading to Win 8.1. The last one just announced that in 2 days Win 8.1 would download & my computer would restart. So, it looks like Win 8.1 is going to get forced upon me. My question is with Win 8.1 what programs/apps that I currently have can I expect to stop working? More importantly what am I going to have to do to get everything to work again? I foresee this forced upgrade is going o screw things up big time.
Did Barnes & Noble change their encryption? I cannot decrypt any of my recently-purchased books, and if I download a new copy of a book purchased back in 2011 (and decrypted then), I cannot decrypt it now. Instead, I get either “IGNOBLEError: AES improper key used” or “error: Error -3 while decompressing: invalid stored block lengths”
I’ve tested this on openSUSE 11.3 and 13.1, running ignobleepub.py v1-rc2 (what I’ve been using until now), and version 3.8, the latest from tools 6.0.9. I don’t use Calibre; I run the scripts from a bash shell. I have verified that I can still decrypt older epubs (I always keep the DRM’d original as well as the deDRM’d version)–the version I downloaded 9/29/2011 decrypts fine with either version of ignobleepub.py. A fresh version downloaded today results in “IGNOBLEError: AES improper key used”
I have tried recreating the key using ignoblekeygen.py; the key is identical to the one I’ve been using all along.
I have not changed the credit card used, nor my name in my B&N account.
Two sample outputs:
Could not decrypt 9780316246637_Ancillary_Justice.epub because of an exception:
Traceback (most recent call last):

self._aes = AES(bookkey)
File “../DeDRM/ignobleepub.py”, line 158, in __init__
raise IGNOBLEError(‘AES improper key used’)
IGNOBLEError: AES improper key used
Any ideas?
It does seem that B&N have changed their encryption.
Looks like I’m done buying books from B&N. First they take away the ability to download from the website, then change the encryption so I cannot truly own the book.
Not that they care about customers.
Hi, I’m having a problem opening the tools v6.0.9 zip file. When I open the zip files and it unpacks to a cpgz. I’ve tried the fix suggested in the comments, but that doesn’t work for me either: when I ctrl-click, there’s no “show contents” option. Thus I can’t remove the “w” with textedit
There’s no .cpgz file in the tools archive. It’s a problem with your unzipping utility. A quick google reveals this article that might help.

You don’t seem to have Kindle for PC installed, nor have you entered an e-ink Kindle serial number into the plugin’s customisation dialog. The tools can’t remove the DRM without the DRM key.
I use Kindle for PC and Calibre on my Win7 desktop PC and conversion from AZW3 to EPUB always worked fine with your plugin. But since I installed the same configuration on my laptop and bought/converted Amazon ebooks there, the conversion is not working anymore on my desktop PC. It just says that the ebook is DRM protected and doesn’t even write any debug log. It’s really strange, because I can still open all books in Kindle for PC on the desktop PC, just conversion in Calibre does not work anymore. Thanks in advance for any helpful hint.
Post an import log.
Is that the output you get when starting Calibre in debug mode from the command line? I hope that’s what you meant:
