-From Apprentice Alf's Blog
-
-Adobe Adept ePub and PDF, .epub, .pdf
-
-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.
-
-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_v5.1.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_v5.3.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.
-
-The latest version of ineptpdf to use is version 8.4.42, which improves support for some PDF files. 
-
-ineptpdf version 8.4.42 can be found here:

-It is not included in the tools archive.

-Barnes and Noble EPUB ebooks use a form of Social DRM which requires information on your Credit Card Number and the Name on the Credit card used to purchase the book to actually unencrypt the book.
-
-For more info, see the author's blog:
-http://i-u2665-cabbages.blogspot.com/2009_12_01_archive.html
-
-The original scripts by IHeartCabbages are available here as well.  These scripts have been modified to allow the use of OpenSSL in place of PyCrypto to make them easier to run on Linux and Mac OS X. 
-
-There are 2 scripts:
-
-The first is ignoblekeygen_v2.pyw.  Double-click to launch it and provide the required information, and this program will generate a key file needed to remove the DRM from the books.  This key file need only be generated once unless either you change your credit card number or your name on the credit card (or if you use a different credit card to purchase your book).
-
-The second is ignobleepub_v3.pyw.  Double-click it and it will ask for your key file and the path to the book to remove the DRM from.
-
-All 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.
-
-These scripts are based on the IHeartCabbages original scripts that allow the replacement of the requirement for PyCrypto with OpenSSL's libcrypto which is already installed on all Mac OS X machines and Linux Boxes.  Window's Users will still have to install PyCrypto or OpenSSL to get these scripts to work properly.

+# Using the DeDRM plugin with the Calibre command line interface
+
+If you prefer the Calibre CLI instead of the GUI, follow this guide to
+install and use the DeDRM plugin.
+
+This guide assumes you are on Linux, but it may very well work on other
+platforms.
+
+## Step-by-step Tutorial
+
+#### Install Calibre
+   - Follow [Calibre's installation instructions](https://calibre-ebook.com/download_linux)
+
+#### Install plugins
+  - Download the DeDRM `.zip` archive from DeDRM_tools'
+     [latest release](https://github.com/apprenticeharper/DeDRM_tools/releases/latest).
+     Then unzip it.
+  - Add the DeDRM plugin to Calibre:
+     ```
+     cd *the unzipped DeDRM_tools folder*
+     calibre-customize --add DeDRM_calibre_plugin/DeDRM_plugin.zip
+     ```
+  - Add the Obok plugin:
+    ```
+    calibre-customize --add Obok_calibre_plugin/obok_plugin.zip
+    ```
+
+#### Enter your keys
+  - Figure out what format DeDRM wants your key in by looking in
+     [the code that handles that](dedrm_src/prefs.py).
+     - For Kindle eInk devices, DeDRM expects you to put a list of serial
+       numbers in the `serials` field: `"serials": ["012345689abcdef"]` or
+       `"serials": ["1111111111111111", "2222222222222222"]`.
+  - Now add your keys to `$CALIBRE_CONFIG_DIRECTORY/plugins/dedrm.json`.
+
+#### Import your books
+  - Make a library folder
+  ```
+  mkdir library
+  ```
+  - Add your book(s) with this command:
+  ```
+  calibredb add /path/to/book.format --with-library=library
+  ```
+
+The DRM should be removed from your book, which you can find in the `library`
+folder.

-Plugin for K4PC, K4Mac and Mobi Books
-
-Will work on Linux (standard DRM Mobi books only), Mac OS X (standard DRM Mobi books and "Kindle for Mac" books, and Windows (standard DRM Mobi books and "Kindle for PC" books.
-
-This plugin supersedes MobiDeDRM, K4DeDRM, and K4PCDeDRM plugins.  If you install this plugin, those plugins can be safely removed.
-
-This plugin is meant to convert "Kindle for PC", "Kindle for Mac" and "Mobi" ebooks with DRM to unlocked Mobi files. 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.
-
-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. This is not needed if you only want to decode "Kindle for PC" or "Kindle for Mac" books. 
-
-
-Troubleshooting:
-If you find that it's not working for you (imported azw's are not converted to mobi format), you can save a lot of time and trouble by trying to add the azw file 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.azw". Don't type the quotes and obviously change the 'your_ebook.azw' 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.

-eReader PDB2PML - eReaderPDB2PML_vXX_plugin.zip
-
-All credit given to The Dark Reverser for the original standalone script. I had the much easier job of converting it to a Calibre plugin.
-
-This plugin is meant to convert secure Ereader files (PDB) to unsecured PMLZ files. Calibre can then convert it to whatever format you desire. It is meant to function without having to install any  dependencies... other than having Calibre installed, of course. I've included the psyco libraries (compiled for each platform) for speed. If your system can use them, great! Otherwise, they won't be used and things will just work slower.
-
-Installation:
-Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file  (eReaderPDB2PML_vXX_plugin.zip) and click the 'Add' button. You're done.
-
-Configuration:
-Highlight the plugin (eReader PDB 2 PML under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. Enter your name and last 8 digits of the credit card number separated by a comma: Your Name,12341234
-
-If you've purchased books with more than one credit card, separate the info with a colon: Your Name,12341234:Other Name,23452345 (NOTE: Do NOT put quotes around your name like you do with the original script!!)

-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 them 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

-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.

-# 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.

-# customization window. 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 the info with
-# a colon: Your Name,1234123412341234:Other Name,2345234523452345
-#
-# ** Method 1 is your only option if you don't have/can't run the original
-# I <3 Cabbages scripts on your particular machine. **
-#
-# 2) If you already have keyfiles generated with I <3 Cabbages' ignoblekeygen.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 '.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 option 2 and all data entered from option 1 will be used to attempt
-# to decrypt a book. You can use option 1 or option 2, or a combination of both.

-
-# ineptepub_plugin.py
-# Released under the terms of the GNU General Public Licence, version 3 or
-# later.  <http://www.gnu.org/licenses/>
-#
-# 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.
-#
-# 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 ADE installation. So if you have ADE installed on the same machine as Calibre...
-# you are ready to go.
-#
-# 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.
-#
-# Revision history:
-#   0.1 - Initial release
-#   0.1.1 - Allow Windows users to make use of openssl if they have it installed.
-#          - Incorporated SomeUpdates zipfix routine.

-# engine to remove drm from Kindle for Mac and Kindle for PC books
-# for personal use for archiving and converting your ebooks
-
-# PLEASE DO NOT PIRATE EBOOKS! 
-
-# We want all authors and publishers, and eBook stores to live
-# long and prosperous lives but at the same time  we just want to 
-# be able to read OUR books on whatever device we want and to keep 
-# readable for a long, long time
-
-#  This borrows very heavily from works by CMBDTC, IHeartCabbages, skindle, 
-#    unswindle, DarkReverser, ApprenticeAlf, DiapDealer, some_updates 
-#    and many many others
-
-# It can run standalone to convert K4M/K4PC/Mobi files, or it can be installed as a
-# plugin for Calibre (http://calibre-ebook.com/about) so that importing
-# K4 or Mobi with DRM is no londer a multi-step process.
-#
-# ***NOTE*** If you are using this script as a calibre plugin for a K4M or K4PC ebook
-# then calibre must be installed on the same machine and in the same account as K4PC or K4M
-# 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 with all its supporting python routines
-# and import that ZIP into 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 '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.

-# ***NOTE*** If you are using this script as a calibre plugin for a K4M or K4PC ebook
-# then calibre must be installed on the same machine and in the same account as K4PC or K4M
-# for the plugin version to function properly.
-#
-# To create a Calibre plugin, rename this file so that the filename
