 This plugin is meant to remove the DRM from .prc, .azw, .azw1, and .tpz ebooks.   Calibre can then convert them to whatever format you desire. It is meant to function without having to install any  dependencies except for Calibre being on your same machine and in the same account as your "Kindle for PC" or "Kindle for Mac" application if you are going to remove the DRM from those types of books.

 

 Installation:

-Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file  (K4MobiDeDRM_vXX_plugin.zip) and click the 'Add' button. You're done.
+Go to Calibre's Preferences page... click on the Plugins button. Click on the "Add a new plugin" button at the bottom of the screen.  Use the file dialog button to select the plugin's zip file  (K4MobiDeDRM_vXX_plugin.zip) and click the "Add" (or it may say "Open" button.  Then click on the "Yes" button in the warning dialog that appears.  A Confirmation dialog appears that says the plugin has been installed.

-Please note:  Calibre does not provide any immediate feedback to indicate that adding the plugin was a success. You can always click on the File-Type plugins to see if the plugin was added.

-

 Configuration:

-Highlight the plugin (K4MobiDeDRM under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. Enter a comma separated list of your 10 digit PIDs.  Include in this list (again separated by commas) any 16 digit serial numbers the standalone Kindles you may have (these typically begin "B0...")  This is not needed if you only want to decode "Kindle for PC" or "Kindle for Mac" books. 
+Highlight the plugin (K4MobiDeDRM under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. Enter your 10 digit PID.

-# This is a python script. You need a Python interpreter to run it.
-# For example, ActiveState Python, which exists for windows.
-#
-# Changelog
-#  0.01 - Initial version
-#  0.02 - Huffdic compressed books were not properly decrypted
-#  0.03 - Wasn't checking MOBI header length
-#  0.04 - Wasn't sanity checking size of data record
-#  0.05 - It seems that the extra data flags take two bytes not four
-#  0.06 - And that low bit does mean something after all :-)
-#  0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
-#  0.08 - ...and also not in Mobi header version < 6
-#  0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
-#  0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
-#         import filter it works when importing unencrypted files.
-#         Also now handles encrypted files that don't need a specific PID.
-#  0.11 - use autoflushed stdout and proper return values
-#  0.12 - Fix for problems with metadata import as Calibre plugin, report errors
-#  0.13 - Formatting fixes: retabbed file, removed trailing whitespace
-#         and extra blank lines, converted CR/LF pairs at ends of each line,
-#         and other cosmetic fixes.
-#  0.14 - Working out when the extra data flags are present has been problematic
-#         Versions 7 through 9 have tried to tweak the conditions, but have been
-#         only partially successful. Closer examination of lots of sample
-#         files reveals that a confusion has arisen because trailing data entries
-#         are not encrypted, but it turns out that the multibyte entries
-#         in utf8 file are encrypted. (Although neither kind gets compressed.)
-#         This knowledge leads to a simplification of the test for the 
-#         trailing data byte flags - version 5 and higher AND header size >= 0xE4. 
-#  0.15 - Now outputs 'heartbeat', and is also quicker for long files.
-#  0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
-#  0.17 - added modifications to support its use as an imported python module
-#         both inside calibre and also in other places (ie K4DeDRM tools)
-#  0.17a- disabled the standalone plugin feature since a plugin can not import
-#         a plugin
-#  0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
-#         Removed the disabled Calibre plug-in code
-#         Permit use of 8-digit PIDs
-#  0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
-#  0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
-#  0.21 - Added support for multiple pids
-#  0.22 - revised structure to hold MobiBook as a class to allow an extended interface
-#  0.23 - fixed problem with older files with no EXTH section 
-#  0.24 - add support for type 1 encryption and 'TEXtREAd' books as well
-#  0.25 - Fixed support for 'BOOKMOBI' type 1 encryption
-#  0.26 - Now enables Text-To-Speech flag and sets clipping limit to 100%
-#  0.27 - Correct pid metadata token generation to match that used by skindle (Thank You Bart!)
-#  0.28 - slight additional changes to metadata token generation (None -> '')
-#  0.29 - It seems that the ideas about when multibyte trailing characters were
-#         included in the encryption were wrong. They aren't for DOC compressed
-#         files, but they are for HUFF/CDIC compress files!

-Prerequisites:
-
-   - Kindle for Mac.app Version 1.0.0 Beta 1 (27214)
-	or
-     Kindle.app Version 1.2.0 (30689)
-        or
-     Kindle.app Version 1.2.1 (30781)
-     	or
-     Kindle.app Version 1.2.2 (30814)
-     (this is now the current version)
-
-   - A **recent** version of the XCode Developer Tools **must** be Installed 
-    (see your latest Mac OS X Install Disk for the installer, and then use Apple System Updates)
-
-***PLEASE REMEMBER to UNCHECK the "auto updates" in the Kindle.app Preferences!
-***otherwise it will always update and K4MUnswindle will stop working
-
-
-The directions for use are:
-
-1. double-click on K4Munswindle.pyw
-
-In the window that opens:
-
-– hit the first '...' button to locate your Kindle Application 
-     if it is not in /Applications
-
-– hit the second '...' button to select an output directory 
-      (defaults to your Desktop)
-
-– hit the 'Start' button
-
-After a short delay, your Kindle application should open up automagically
-
-2. In Kindle for Mac:
-
- - hit the  “Home” button to go home. 
-
- - double-click on ONE of your books.
-   This should open the book.
-
-3. Once the book you want is open
-
--  hit the “Home” button and then exit the Kindle for Mac application
-
-4. Once you have exited the Kindle for Mac application you should see one of the following:
-
-  - If the book you selected was a Topaz Book:
-
-      A Warning message will appear in the Conversion Log indicating 
-      that the book you opened was Topaz, along with the 8 digit PID 
-      needed to convert it using Topaz_Tools
-
-  - If the book you selected was a Mobi book:
-
-      MobiDeDRM will be automagically started in the Conversion Log 
-      window and if successful you should find your decoded book in 
-      the output directory.

-# This is a python script. You need a Python interpreter to run it.
-# For example, ActiveState Python, which exists for windows.
-#
-# Changelog
-#  0.01 - Initial version
-#  0.02 - Huffdic compressed books were not properly decrypted
-#  0.03 - Wasn't checking MOBI header length
-#  0.04 - Wasn't sanity checking size of data record
-#  0.05 - It seems that the extra data flags take two bytes not four
-#  0.06 - And that low bit does mean something after all :-)
-#  0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
-#  0.08 - ...and also not in Mobi header version < 6
-#  0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
-#  0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
-#         import filter it works when importing unencrypted files.
-#         Also now handles encrypted files that don't need a specific PID.
-#  0.11 - use autoflushed stdout and proper return values
-#  0.12 - Fix for problems with metadata import as Calibre plugin, report errors
-#  0.13 - Formatting fixes: retabbed file, removed trailing whitespace
-#         and extra blank lines, converted CR/LF pairs at ends of each line,
-#         and other cosmetic fixes.
-#  0.14 - Working out when the extra data flags are present has been problematic
-#         Versions 7 through 9 have tried to tweak the conditions, but have been
-#         only partially successful. Closer examination of lots of sample
-#         files reveals that a confusion has arisen because trailing data entries
-#         are not encrypted, but it turns out that the multibyte entries
-#         in utf8 file are encrypted. (Although neither kind gets compressed.)
-#         This knowledge leads to a simplification of the test for the 
-#         trailing data byte flags - version 5 and higher AND header size >= 0xE4. 
-#  0.15 - Now outputs 'heartbeat', and is also quicker for long files.
-#  0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
-#  0.17 - added modifications to support its use as an imported python module
-#         both inside calibre and also in other places (ie K4DeDRM tools)
-#  0.17a- disabled the standalone plugin feature since a plugin can not import
-#         a plugin
-#  0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
-#         Removed the disabled Calibre plug-in code
-#         Permit use of 8-digit PIDs
-#  0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
-#  0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
-#  0.21 - Added support for multiple pids
-#  0.22 - revised structure to hold MobiBook as a class to allow an extended interface
-#  0.23 - fixed problem with older files with no EXTH section 
-#  0.24 - add support for type 1 encryption and 'TEXtREAd' books as well
-#  0.25 - Fixed support for 'BOOKMOBI' type 1 encryption
-#  0.26 - Now enables Text-To-Speech flag and sets clipping limit to 100%
-#  0.27 - Correct pid metadata token generation to match that used by skindle (Thank You Bart!)
-#  0.28 - slight additional changes to metadata token generation (None -> '')
-#  0.29 - It seems that the ideas about when multibyte trailing characters were
-#         included in the encryption were wrong. They aren't for DOC compressed
-#         files, but they are for HUFF/CDIC compress files!

-unswindle can be used to find the book specific PID but it needs to be updated for each version of Kindle4PC that Amazon releases (and therefore is also useful for Linux users who have Wine). This program “patches” the Kindle4PC executable and therefore is very release specific.
-
-Unfortunately unswindle v7 the latest, has not been updated to work with the latest version of Kindle for PC.  You will need to find one of the older versions of Kindle4PC and prevent later updates in order to use this tool.

+Kindle for Android
+------------------
+
+Kindle for Android uses a different scheme to generate its books specific PIDs than Kindle for PC, Kindle for iPhone/iPad, and standalone Kindles.
+
+Unfortunately, K4Android uses an "account secrets" file that would only be available if the device were jail-broken and even then someone would have to figure out how to decode this secret information in order to reverse the process.
+
+Instead of trying to calculate the correct PIDs for each book from this primary data, "Me" (a commenter who posted to the ApprenticeAlf site)  came up with a wonderful idea to simply modify the Kindle 3 for Android application to store the PIDs it uses to decode each book in its "about activity" window.  This list of PIDS can then be provided to MobiDeDRM.py,  which in its latest incarnations allows a comma separated list of pids to be passed in, to successfully remove the DRM from that book.   Effectively "Me" has created an "Unswindle" for the Kindle for Android 3 application!
+
+Obviously, to use "Me"'s approach, requires an Android Developer's Certificate (to sign the modified application) and access to and knowledge of the developer tools, but does not require anything to be jail-broken.
+
+This is a copy the detailed instructions supplied by "Me" to the ApprenticeAlf blog in the comments.  The kindle3.patch described below is included in this folder in the tools:
+ 
+From the ApprenticeAlf Comments:
+
+"Me" writes:
+
+A better solution seems to create a patched version of the Kindle apk which either logs or displays it’s PID. I created a patch to both log the pid list and show it in the Kindle application in the about activity screen. The pid list isn’t available until the DRMed book has been opened (and the list seem to differ for different books).
+
+To create the patched kindle apk a certificate must be created (http://developer.android.com/guide/publishing/app-signing.html#cert) and the apktool must be build from source (all subprojects) as long as version 1.4.2 isn’t released (http://code.google.com/p/android-apktool/wiki/BuildApktool).
+
+These are the steps to pull the original apk from the Android device, uninstall it, create a patched apk and install that (tested on a rooted device, but I think all steps should also work on non-rooted devices):
+
+adb pull /data/app/com.amazon.kindle-1.apk kindle3.apk
+adb uninstall com.amazon.kindle
+apktool d kindle3.apk kindle3
+cd kindle3
+patch -p1 < ..\kindle3.patch
+cd ..
+apktool b kindle3 kindle3_patched.apk
+jarsigner -verbose -keystore kindle.keystore kindle3_patched.apk kindle
+zipalign -v 4 kindle3_patched.apk kindle3_signed.apk
+adb install kindle3_signed.apk
+
+kindle3.patch (based on kindle version 3.0.1.70) is available on pastebin:

+Have fun!

+
+Hi me,
+Wow! Great work!!!!
+
+With your patch, you have created the equivalent of Unswindle for the Kindle for Android app and it does not even require jailbreaking!
+
+Very nice work indeed!
