-The wonderful I♥CABBAGES has produced scripts that will remove the DRM from ePubs and PDFs encryped with Adobe’s DRM. Installing these scripts is a little more complex that the Mobipocket and eReader decryption tools, as they require installation of the PyCrypto package for Windows Boxes.  For Mac OS X and Linux boxes, these scripts use the already installed OpenSSL libcrypto so there is no additional requirements for these platforms.
+This directory includes modified versions of the I♥CABBAGES Adobe Adept inept scripts for epubs.  These scripts have been modified to work with OpenSSL on Windows as well as Linux and Mac OS X.  His original scripts can be found in the clearly labelled folder.  If a Windows User has OpenSSL installed, these scripts will make use of it in place of PyCrypto.

 For more info, see the author's blog:
 http://i-u2665-cabbages.blogspot.com/2009_02_01_archive.html
 
 There are two scripts:
 
-The first is called ineptkey_v5.pyw.  Simply double-click to launch it and it will create a key file that is needed later to actually remove the DRM.  This script need only be run once unless you change your ADE account information.
-
-The second is called in ineptepub_v5.pyw.  Simply double-click to launch it.  It will ask for your previously generated key file and the path to the book you want to remove the DRM from.
+The first is called ineptkey_vX.X.pyw.  Simply double-click to launch it and it will create a key file that is needed later to actually remove the DRM.  This script need only be run once unless you change your ADE account information.

 Both of these scripts are gui python programs.   Python 2.X (32 bit) is already installed in Mac OSX.  We recommend ActiveState's Active Python Version 2.X (32 bit) for Windows users.

-The latest version of ineptpdf to use is version 8.4.42, which improves support for some PDF files.

+Adobe Adept PDF, .pdf
+
+This directory includes modified versions of the I♥CABBAGES Adobe Adept inept scripts for pdfs.  These scripts have been modified to work with OpenSSL on Windows as well as Linux and Mac OS X.  If a Windows User has OpenSSL installed, these scripts will make use of it in place of PyCrypto.
+
+The wonderful I♥CABBAGES has produced scripts that will remove the DRM from ePubs and PDFs encryped with Adobe’s DRM. These scripts require installation of the PyCrypto python package *or* the OpenSSL library on Windows.  For Mac OS X and Linux boxes, these scripts use the already installed OpenSSL libcrypto so there is no additional requirements for these platforms.
+
+For more info, see the author's blog:
+http://i-u2665-cabbages.blogspot.com/2009_02_01_archive.html
+
+There are two scripts:
+
+The first is called ineptkey_vX.X.pyw.  Simply double-click to launch it and it will create a key file that is needed later to actually remove the DRM.  This script need only be run once unless you change your ADE account information.
+
+The second is called in ineptpdf_vX.X.pyw.  Simply double-click to launch it.  It will ask for your previously generated key file and the path to the book you want to remove the DRM from.
+
+Both of these scripts are gui python programs.   Python 2.X (32 bit) is already installed in Mac OSX.  We recommend ActiveState's Active Python Version 2.X (32 bit) for Windows users.

-# This is a WINDOWS python script. You need a Python interpreter to run it.
-# For example, ActiveState Python, which exists for windows.
-#
-# It can run standalone to convert K4PC files, or it can be installed as a
-# plugin for Calibre (http://calibre-ebook.com/about) so that importing
-# K4PC files with DRM is no londer a multi-step process.
-#
-# ***NOTE*** Calibre and K4PC must be installed on the same windows machine
-# for the plugin version to function properly.
-#
-# To create a Calibre plugin, rename this file so that the filename
-# ends in '_plugin.py', put it into a ZIP file and import that ZIP into Calibre
-# using its plugin configuration GUI.
-#
-# Thanks to The Dark Reverser for MobiDeDrm and CMBDTC for cmbdtc_dump from
-# which this script steals most unashamedly.
-#
-# Changelog
-#  0.01 - Initial version - Utilizes skindle and CMBDTC method of obtaining
-#         book specific pids from K4PC books. If Calibre and K4PC are installed
-#         on the same windows machine, Calibre plugin functionality is once
-#         again restored.

-# This is a python script. You need a Python interpreter to run it.
-# For example, ActiveState Python, which exists for windows.
-#
-# It can run standalone to convert files, or it can be installed as a
-# plugin for Calibre (http://calibre-ebook.com/about) so that
-# importing files with DRM 'Just Works'.
-#
-# To create a Calibre plugin, rename this file so that the filename
-# ends in '_plugin.py', put it into a ZIP file and import that Calibre
-# using its plugin configuration GUI.
-#
-# 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 confusin 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 'hearbeat', and is also quicker for long files.
-#  0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.

+Inept PDF Plugin - ineptpdf_vXX_plugin.zip
+
+Requires Calibre version 0.6.44 or higher.
+
+
+
+All credit given to IHeartCabbages for the original standalone scripts.
+
+I had the much easier job of converting them to a Calibre plugin.
+
+
+
+This plugin is meant to decrypt Adobe Digital Edition PDFs that are protected with Adobe's Adept encryption. It is meant to function without having to install any dependencies... other than having Calibre installed, of course. It will still work if you have Python, PyCrypto and/or OpenSSL already installed, but they aren't necessary.
+
+
+
+Installation:
+
+
+
+Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file (ineptpdf_vXX_plugin.zip) and click the 'Add' button. you're done.
+
+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:
+
+
+
+When first run, the plugin will attempt to find your Adobe Digital Editions installation (on Windows and Mac OS's). If successful, it will create an 'adeptkey.der' file and save it in Calibre's configuration directory. It will use that file on subsequent runs. If there are already '*.der' files in the directory, the plugin won't attempt to
+
+find the Adobe Digital Editions installation installation.
+
+
+
+So if you have Adobe Digital Editions installation installed on the same machine as Calibre... you are ready to go. If not... keep reading.

+Plugin for K4PC, K4Mac, standalone Kindles, Mobi Books, and for Devices with Fixed PIDs.
+
+This plugin supersedes MobiDeDRM, K4DeDRM, and K4PCDeDRM and K4X plugins.  If you install this plugin, those plugins can be safely removed.
+
+
+
+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.

-Ignoble Epub DeDRM - ignobleepub_vXX_plugin.zip
-Requires Calibre version 0.6.44 or higher.
-
-All credit given to I <3 Cabbages for the original standalone scripts.
-I had the much easier job of converting them to a Calibre plugin.
-
-This plugin is meant to decrypt Barnes & Noble Epubs that are protected
-with Adobe's Adept encryption. It is meant to function without having to install
-any dependencies... other than having Calibre installed, of course. It will still
-work if you have Python and PyCrypto already installed, but they aren't necessary.
-
-Installation:
-
-Go to Calibre's Preferences page... click on the Plugins button. Use the file
-dialog button to select the plugin's zip file (ignobleepub_vXX_plugin.zip) and
-click the 'Add' button. you're done.
-
-Configuration:
-
-1) The easiest way to configure the plugin is to enter your name (Barnes & Noble account
-name) and credit card number (the one used to purchase the books) into the plugin's
-customization window. It's the same info you would enter into the ignoblekeygen script.
-Highlight the plugin (Ignoble Epub DeDRM) and click the "Customize Plugin" button on
-Calibre's Preferences->Plugins page. Enter the name and credit card number separated
-by a comma: Your Name,1234123412341234
-
-If you've purchased books with more than one credit card, separate that other info with
-a colon: Your Name,1234123412341234:Other Name,2345234523452345
-
-** NOTE ** The above method is your only option if you don't have/can't run the original
-I <3 Cabbages scripts on your particular machine.
-
-** NOTE ** Your credit card number will be on display in Calibre's Plugin configuration
-page when using the above method. If other people have access to your computer,
-you may want to use the second configuration method below.
-
-2) If you already have keyfiles generated with I <3 Cabbages' ignoblekeygen.pyw
-script, you can put those keyfiles into Calibre's configuration directory. The easiest
-way to find the correct directory is to go to Calibre's Preferences page... click
-on the 'Miscellaneous' button (looks like a gear),  and then click the 'Open Calibre
-configuration directory' button. Paste your keyfiles in there. Just make sure that
-they have different names and are saved with the '.b64' extension (like the ignoblekeygen
-script produces). This directory isn't touched when upgrading Calibre, so it's quite safe
-to leave then there.
-
-All keyfiles from method 2 and all data entered from method 1 will be used to attempt
-to decrypt a book. You can use method 1 or method 2, or a combination of both.
-
-Troubleshooting:
-
-If you find that it's not working for you (imported epubs still have DRM), you can
-save a lot of time and trouble by trying to add the epub to Calibre with the command
-line tools. This will print out a lot of helpful debugging info that can be copied into
-any online help requests. I'm going to ask you to do it first, anyway, so you might
-as well get used to it. ;)
-
-Open a command prompt (terminal) and change to the directory where the ebook you're
-trying to import resides. Then type the command "calibredb add your_ebook.epub".
-Don't type the quotes and obviously change the 'your_ebook.epub' to whatever the
-filename of your book is. Copy the resulting output and paste it into any online
-help request you make.
-
-** Note: the Mac version of Calibre doesn't install the command line tools by default.
-If you go to the 'Preferences' page and click on the miscellaneous button, you'll
-see the option to install the command line tools.

-Inept Epub DeDRM - ineptepub_vXX_plugin.zip
-Requires Calibre version 0.6.44 or higher.
-
-All credit given to I <3 Cabbages for the original standalone scripts.
-I had the much easier job of converting them to a Calibre plugin.
-
-This plugin is meant to decrypt Adobe Digital Edition Epubs that are protected
-with Adobe's Adept encryption. It is meant to function without having to install
-any dependencies... other than having Calibre installed, of course. It will still
-work if you have Python and PyCrypto already installed, but they aren't necessary.
-
-Installation:
-
-Go to Calibre's Preferences page... click on the Plugins button. Use the file
-dialog button to select the plugin's zip file (ineptepub_vXX_plugin.zip) and
-click the 'Add' button. you're done.
-
-Configuration:
-
-When first run, the plugin will attempt to find your Adobe Digital Editions installation
-(on Windows and Mac OS's). If successful, it will create an 'adeptkey.der' file and
-save it in Calibre's configuration directory. It will use that file on subsequent runs.
-If there are already '*.der' files in the directory, the plugin won't attempt to
-find the Adobe Digital Editions installation installation.
-
-So if you have Adobe Digital Editions installation installed on the same machine as Calibre...
-you are ready to go. If not... keep reading.
-
-If you already have keyfiles generated with I <3 Cabbages' ineptkey.pyw script,
-you can put those keyfiles in Calibre's configuration directory. The easiest
-way to find the correct directory is to go to Calibre's Preferences page... click
-on the 'Miscellaneous' button (looks like a gear),  and then click the 'Open Calibre
-configuration directory' button. Paste your keyfiles in there. Just make sure that
-they have different names and are saved with the '.der' extension (like the ineptkey
-script produces). This directory isn't touched when upgrading Calibre, so it's quite
-safe to leave them there.
-
-Since there is no Linux version of Adobe Digital Editions, Linux users will have to
-obtain a keyfile through other methods and put the file in Calibre's configuration directory.
-
-All keyfiles with a '.der' extension found in Calibre's configuration directory will
-be used to attempt to decrypt a book.
-
-** NOTE ** There is no plugin customization data for the Inept Epub DeDRM plugin.
-
-Troubleshooting:
-
-If you find that it's not working for you (imported epubs still have DRM), you can
-save a lot of time and trouble by trying to add the epub to Calibre with the command
-line tools. This will print out a lot of helpful debugging info that can be copied into
-any online help requests. I'm going to ask you to do it first, anyway, so you might
-as well get used to it. ;)
-
-Open a command prompt (terminal) and change to the directory where the ebook you're
-trying to import resides. Then type the command "calibredb add your_ebook.epub".
-Don't type the quotes and obviously change the 'your_ebook.epub' to whatever the
-filename of your book is. Copy the resulting output and paste it into any online
-help request you make.
-
-** Note: the Mac version of Calibre doesn't install the command line tools by default.
-If you go to the 'Preferences' page and click on the miscellaneous button, you'll
-see the option to install the command line tools.

+# 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!

+# Changelog
+#
+#  Based on ereader2html version 0.08 plus some later small fixes
+#
+#  0.01 - Initial version
+#  0.02 - Support more eReader files. Support bold text and links. Fix PML decoder parsing bug.
+#  0.03 - Fix incorrect variable usage at one place.
+#  0.03b - enhancement by DeBockle (version 259 support)
+# Custom version 0.03 - no change to eReader support, only usability changes
+#   - start of pep-8 indentation (spaces not tab), fix trailing blanks
+#   - version variable, only one place to change
+#   - added main routine, now callable as a library/module, 
+#     means tools can add optional support for ereader2html
+#   - outdir is no longer a mandatory parameter (defaults based on input name if missing)
+#   - time taken output to stdout
+#   - Psyco support - reduces runtime by a factor of (over) 3!
+#     E.g. (~600Kb file) 90 secs down to 24 secs
+#       - newstyle classes
+#       - changed map call to list comprehension
+#         may not work with python 2.3
+#         without Psyco this reduces runtime to 90%
+#         E.g. 90 secs down to 77 secs
+#         Psyco with map calls takes longer, do not run with map in Psyco JIT!
+#       - izip calls used instead of zip (if available), further reduction
+#         in run time (factor of 4.5).
+#         E.g. (~600Kb file) 90 secs down to 20 secs
+#   - Python 2.6+ support, avoid DeprecationWarning with sha/sha1
+#  0.04 - Footnote support, PML output, correct charset in html, support more PML tags
+#   - Feature change, dump out PML file
+#   - Added supprt for footnote tags. NOTE footnote ids appear to be bad (not usable)
+#       in some pdb files :-( due to the same id being used multiple times
+#   - Added correct charset encoding (pml is based on cp1252)
+#   - Added logging support.
+#  0.05 - Improved type 272 support for sidebars, links, chapters, metainfo, etc
+#  0.06 - Merge of 0.04 and 0.05. Improved HTML output
+#         Placed images in subfolder, so that it's possible to just
+#         drop the book.pml file onto DropBook to make an unencrypted
+#         copy of the eReader file.
+#         Using that with Calibre works a lot better than the HTML
+#         conversion in this code.
+#  0.07 - Further Improved type 272 support for sidebars with all earlier fixes
+#  0.08 - fixed typos, removed extraneous things
+#  0.09 - fixed typos in first_pages to first_page to again support older formats
+#  0.10 - minor cleanups
+#  0.11 - fixups for using correct xml for footnotes and sidebars for use with Dropbook
+#  0.12 - Fix added to prevent lowercasing of image names when the pml code itself uses a different case in the link name.
+#  0.13 - change to unbuffered stdout for use with gui front ends
+#  0.14 - contributed enhancement to support --make-pmlz switch
+#  0.15 - enabled high-ascii to pml character encoding. DropBook now works on Mac.
+#  0.16 - convert to use openssl DES (very very fast) or pure python DES if openssl's libcrypto is not available
+#  0.17 - added support for pycrypto's DES as well
+#  0.18 - on Windows try PyCrypto first and OpenSSL next
+#  0.19 - Modify the interface to allow use of import
+
