Posted on September 10, 2012 by Apprentice Alf

Last updated on 12th August, 2014

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.

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.

  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

    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.

  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.

        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.

    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;
  eReader PDB 2 PML (0.0.8) by DiapDealer, Apprentice Alf and The Dark Reverser
  Removes DRM from secure pdb files. Credit given to The Dark Reverser for the original standalone
  script.
  Customization: scrimshaw,10698062
  Inept Epub DeDRM (0.2.1) by DiapDealer, Apprentice Alf and i♥cabbages
  Removes DRM from secure Adobe epub files. Credit given to i♥cabbages for the original stand-alone
  scripts.
  Inept PDF DeDRM (0.1.9) by DiapDealer, Apprentice Alf and i♥cabbages
  Removes DRM from secure Adobe pdf files. Credit given to i♥cabbages for the original stand-alone
  scripts.
  Kindle and Mobipocket DeDRM (0.4.18) by DiapDealer, SomeUpdates, mdlnx, Apprentice Alf and The Dark Reverser
  Removes DRM from eInk Kindle, Kindle 4 Mac and Kindle 4 PC ebooks, and from Mobipocket ebooks.
  Provided by the work of many including The Dark Reverser, DiapDealer, SomeUpdates, i♥cabbages,
  CMBDTC, Skindle, mdlnx, ApprenticeAlf, and probably others.
  
  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.

    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.

  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.

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.

  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.

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.

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.

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?

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.

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.

      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

    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.

  You use KindleUnpack to unpack the AZW4 because it’s a PDF in a Mobi wrapper.

  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.

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.

  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.

      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.

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.

  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.

        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.

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’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 :-)

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?

  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.

      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).

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 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.

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.

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?

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.

  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.

Hello

I have downloaded the latest Version of Calibre (2.3.0),

With this configuration I tried to convert a AZW-Book (see below), but it failed.

I wonder, what was wrong

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.

  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?

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.

here is the log

  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.

    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.

        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.

I imported Kindle .azw to Calibre (plug in already installed). However, when I converted it to PDF, got this error. Please help. 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).

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?

  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. ; )

        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.

        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.

        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.)

  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 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.

  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.

        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.)

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.

      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.

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.

Latest plugin is installed in Calibre 2.4.0 (latest), and Kindle serial number has been properly entered in the plug-in’s settings.

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.

    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.

        OK, silly question time: You can now read this PDF with your installed Adobe Digital Editions?

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!

  In addition to first and last name and gmail address I’ve now also tried first name only, last name only, and Mr. Last Name,. I entered the keys and also saved them as “*.b64″ files out of the plug-in customization screen. Although those went to my root user library.

    You just haven’t found the right combo. The name will be one of the versions of your name in your account at the time of download.

  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.

  I suggest you contact the KindleUnpack developers (KevinH especially) through MobileRead. As far as I know, at present there’s nothing that handles azw6.

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:

calibre 2.4 isfrozen: True is64bit: False
Windows-8-6.2.9200 Windows (’32bit’, ‘WindowsPE’)
32bit process running on 64bit windows

Windows: (‘8′, ‘6.2.9200’, ”, ‘Multiprocessor Free’)

  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 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)
