 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:

 Readme.txt
 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.

 Ignoble Epub DeDRM - ignobleepub_v02.5_plugin.zip
 =================================================
 All credit given to i♥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
 ------------
 Do **NOT** select "Get plugins to enhance calibre" as this is reserved for "official" calibre plugins, instead select "Change calibre behavior" to go to Calibre's Preferences page.  Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file (ignobleepub_v02.5_plugin.zip) and click the 'Add' button. Click 'Yes' in the the "Are you sure?" dialog. Click OK in the "Success" dialog.
 Customization
 -------------
 Upon first installing the plugin (or upgrading from a version earlier than 0.2.0), the plugin will be unconfigured. Until you create at least one B&N key—or migrate your existing key(s)/data from an earlier version of the plugin—the plugin will not function. When unconfigured (no saved keys)... an error message will occur whenever ePubs are imported to calibre. To eliminate the error message, open the plugin's customization dialog and create/import/migrate a key (or disable/uninstall the plugin). You can get to the plugin's customization dialog by opening calibre's Preferences dialog, and clicking Plugins (under the Advanced section). Once in the Plugin Preferences, expand the "File type plugins" section and look for the "Ignoble Epub DeDRM" plugin. Highlight that plugin and click the "Customize plugin" button.
 Upgrading from old keys
 If you are upgrading from an earlier version of this plugin and have provided your name(s) and credit card number(s) as part of the old plugin's customization string, you will be prompted to migrate this data to the plugin's new, more secure, key storage method when you open the customization dialog for the first time. If you choose NOT to migrate that data, you will be prompted to save that data as a text file in a location of your choosing. Either way, this plugin will no longer be storing names and credit card numbers in plain sight (or anywhere for that matter) on your computer or in calibre. If you don't choose to migrate OR save the data, that data will be lost. You have been warned!!
 Upon configuring for the first time, you may also be asked if you wish to import your existing *.b64 keyfiles (if you use them) to the plugin's new key storage method. The new plugin no longer looks for keyfiles in calibre's configuration directory, so it's highly recommended that you import any existing keyfiles when prompted ... but you always have the ability to import existing keyfiles anytime you might need/want to.
 If you have upgraded from an earlier version of the plugin, the above instructions may be all you need to do to get the new plugin up and running. Continue reading for new-key generation and existing-key management instructions.
 Creating New Keys:
 On the right-hand side of the plugin's customization dialog, you will see a button with an icon that looks like a green plus sign (+). Clicking this button will open a new dialog for entering the necessary data to generate a new key.
 * Unique Key Name: this is a unique name you choose to help you identify the key after it's created. This name will show in the list of configured keys. Choose something that will help you remember the data (name, cc#) it was created with.
 * Your Name: Your name as set in your Barnes & Noble account, My Account page, directly under PERSONAL INFORMATION. It is usually just your first name and last name separated by a space. This name will not be stored anywhere on your computer or in calibre. It will only be used in the creation of the one-way hash/key that's stored in the preferences.
 * Credit Card number: this is the credit card number that was set as default with Barnes & Noble at the time of download. Nothing fancy here; no dashes or spaces ... just the 16 (15?) digits. Again... this number will not be stored anywhere on your computer or in calibre. It will only be used in the creation of the one-way hash/key that's stored in the preferences.
 Click the 'OK" button to create and store the generated key. Or Cancel if you didn't want to create a key.
 Deleting Keys:
 On the right-hand side of the plugin's customization dialog, you will see a button with an icon that looks like a red "X". Clicking this button will delete the highlighted key in the list. You will be prompted once to be sure that's what you truly mean to do. Once gone, it's permanently gone.
 Exporting Keys:
 On the right-hand side of the plugin's customization dialog, you will see a button with an icon that looks like a computer's hard-drive. Use this button to export the highlighted key to a file (*.b64). Used for backup purposes or to migrate key data to other computers/calibre installations. The dialog will prompt you for a place to save the file.
 Importing Existing Keyfiles:
 At the bottom-left of the plugin's customization dialog, you will see a button labeled "Import Existing Keyfiles". Use this button to import existing *.b64 keyfiles. Used for migrating keyfiles from older versions of the plugin (or keys generated with the original I <3 Cabbages script), or moving keyfiles from computer to computer, or restoring a backup. Some very basic validation is done to try to avoid overwriting already configured keys with incoming, imported keyfiles with the same base file name, but I'm sure that could be broken if someone tried hard. Just take care when importing.
 Once done creating/importing/exporting/deleting decryption keys; click "OK" to exit the customization dialogue (the cancel button will actually work the same way here ... at this point all data/changes are committed already, so take your pick).
 Troubleshooting
 ---------------
 If you find that it's not working for you (imported ebooks still have DRM), you can save a lot of time and trouble by first deleting the DRMed ebook from calibre and then trying to add the ebook 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. ;)
 On Macintosh only you must first run calibre, open Preferences, open Miscellaneous, and click on the “Install command line tools” button. (On Windows and Linux the command line tools are installed automatically.)
 On Windows, open a terminal/command window. (Start/Run… and then type 'cmd' (without the 's) as the program to run).
 On Macintosh, open the Terminal application (in your Utilities folder).
 On Linux open a command window. Hopefully all Linux users know how to do this, as I do not.
 You should now have a text-based command-line window open. Also have open the folder containing the ebook to be imported. Make sure that book isn’t already in calibre, and that calibre isn’t running.
 Now type in "calibredb add " (without the " but don’t miss that final space) and now drag the book to be imported onto the window. The full path to the book should be inserted into the command line. Now press the return/enter key. The import routines will run and produce some logging information.
 Now copy the output from the terminal window.
 On Windows, you must use the window menu (little icon at left of window bar) to select all the text and then to copy it.
 On Macintosh and Linux, just use the normal text select and copy commands.

 Inept Epub DeDRM - ineptepub_v02.0_plugin.zip
 =============================================
 All credit given to i♥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
 ------------
 Do **NOT** select "Get plugins to enhance calibre" as this is reserved for "official" calibre plugins, instead select "Change calibre behavior" to go to Calibre's Preferences page.  Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file (ineptepub_v02.0_plugin.zip) and click the 'Add' button. Click 'Yes' in the the "Are you sure?" dialog. Click OK in the "Success" dialog.
 Customization
 -------------
 When first run, the plugin will attempt to find your Adobe Digital Editions installation (on Windows and Mac OS). If successful, it will create 'calibre-adeptkey[number].der' file(s) and save them in Calibre's configuration directory. It will use those files and any other '*.der' files in any decryption attempts. If there is already at least one 'calibre-adept*.der' file in the directory, the plugin won't attempt to find the Adobe Digital Editions installation keys again.
 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♥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 ebooks still have DRM), you can save a lot of time and trouble by first deleting the DRMed ebook from calibre and then trying to add the ebook to calibre with the command line tools.

 Linux and Adobe Digital Editions ePubs
 --------------------------------------
 Here are the instructions for using the tools with ePub books and Adobe Digital Editions on Linux under Wine. (Thank you mclien!)
 1. download the most recent version of wine from winehq.org (1.3.29 in my case)
 For debian users:
 to get a recent version of wine I decited to use aptosid (2011-02, xfce)
 (because I’m used to debian)
 install aptosid and upgrade it (see aptosid site for detaild instructions)
 2. properly install Wine (see the Wine site for details)
 For debian users:
 cd to this dir and install the packages as root:
 ‘dpkg -i *.deb’
 you will get some error messages, which can be ignored.
 again as root use
 ‘apt-get -f install’ to correct this errors
 3. python 2.7 should already be installed on your system but you may need the following additional python package
 'apt-get install python-tk’
 4. all programms need to be installed as normal user. All these programm are installed the same way:
 ‘wine ‘
 we need:
 a) Adobe Digital Edition 1.7.2(from: http://kb2.adobe.com/cps/403/kb403051.html)
 (there is a “can’t install ADE” site, where the setup.exe hides)
 b) ActivePython-2.7.2.5-win32-x86.msi (from: http://www.activestate.com/activepython/downloads)
 c) Win32OpenSSL_Light-0_9_8r.exe (from: http://www.slproweb.com/)
 d) pycrypto-2.3.win32-py2.7.msi (from: http://www.voidspace.org.uk/python/modules.shtml)
 5. now get and unpack the very latest tools_vX.X (from Apprentice Alf) in the users drive_c of wine
 (~/.wine/drive_c/)
 6. start ADE with:
 ‘wine digitaleditions.exe’ or from the start menue wine-adobe-digital..
 7. register this instance of ADE with your adobeID and close it
 change to the tools_vX.X dir:
 cd ~/.wine/drive_c/tools_vX.X/Other_Tools/
 8. create the adeptkey.der with:
 ‘wine python ineptkey.py’ (only need once!)
 (key will be here: ~/.wine/drive_c/tools_vX.X/Other_Tools/adeptkey.der)
 9. Use ADE running under Wine to dowload all of your purchased ePub ebooks
 10. install the ineptepub and ineptpdf plugins from the tools as discribed in the readmes.
 11. copy the adeptkey.der into the config dir of calibre (~/.config/calibre in debian). Your ADE books imported to calibre will automatically be freed from DRM.

It will use those files and any other '*.der' files in any decryption attempts. If there is already at least one 'calibre-adept*.der' file in the directory, the plugin won't attempt to find the Adobe Digital Editions installation keys again.
 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♥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 PDF plugin.
 Troubleshooting
 ---------------
 If you find that it's not working for you (imported ebooks still have DRM), you can save a lot of time and trouble by first deleting the DRMed ebook from calibre and then trying to add the ebook 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. ;)
 On Macintosh only you must first run calibre, open Preferences, open Miscellaneous, and click on the “Install command line tools” button. (On Windows and Linux the command line tools are installed automatically.)
 On Windows, open a terminal/command window. (Start/Run… and then type ‘cmd’ (without the ‘s) as the program to run).
 On Macintosh, open the Terminal application (in your Utilities folder).
 On Linux open a command window. Hopefully all Linux users know how to do this, as I do not.
 You should now have a text-based command-line window open. Also have open the folder containing the ebook to be imported. Make sure that book isn’t already in calibre, and that calibre isn’t running.
 Now type in "calibredb add " (without the " but don’t miss that final space) and now drag the book to be imported onto the window. The full path to the book should be inserted into the command line. Now press the return/enter key. The import routines will run and produce some logging information.
 Now copy the output from the terminal window.
 On Windows, you must use the window menu (little icon at left of window bar) to select all the text and then to copy it.
 On Macintosh and Linux, just use the normal text select and copy commands.

 Linux and Adobe Digital Editions PDFs
 --------------------------------------
 Here are the instructions for using the tools with ePub books and Adobe Digital Editions on Linux under Wine. (Thank you mclien!)
 1. download the most recent version of wine from winehq.org (1.3.29 in my case)
 For debian users:
 to get a recent version of wine I decited to use aptosid (2011-02, xfce)
 (because I’m used to debian)
 install aptosid and upgrade it (see aptosid site for detaild instructions)
 2. properly install Wine (see the Wine site for details)
 For debian users:
 cd to this dir and install the packages as root:
 ‘dpkg -i *.deb’
 you will get some error messages, which can be ignored.
 again as root use
 ‘apt-get -f install’ to correct this errors
 3. python 2.7 should already be installed on your system but you may need the following additional python package
 'apt-get install python-tk’
 4. all programms need to be installed as normal user. All these programm are installed the same way:
 ‘wine ‘
 we need:
 a) Adobe Digital Edition 1.7.2(from: http://kb2.adobe.com/cps/403/kb403051.html)
 (there is a “can’t install ADE” site, where the setup.exe hides)
 b) ActivePython-2.7.2.5-win32-x86.msi (from: http://www.activestate.com/activepython/downloads)
 c) Win32OpenSSL_Light-0_9_8r.exe (from: http://www.slproweb.com/)
 d) pycrypto-2.3.win32-py2.7.msi (from: http://www.voidspace.org.uk/python/modules.shtml)
 5. now get and unpack the very latest tools_vX.X (from Apprentice Alf) in the users drive_c of wine
 (~/.wine/drive_c/)
 6. start ADE with:
 ‘wine digitaleditions.exe’ or from the start menue wine-adobe-digital..
 7. register this instance of ADE with your adobeID and close it
 change to the tools_vX.X dir:
 cd ~/.wine/drive_c/tools_vX.X/Other_Tools/
 8. create the adeptkey.der with:
 ‘wine python ineptkey.py’ (only need once!)
 (key will be here: ~/.wine/drive_c/tools_vX.X/Other_Tools/adeptkey.der)
 9. Use ADE running under Wine to dowload all of your purchased ePub ebooks
 10. install the ineptepub and ineptpdf plugins from the tools as discribed in the readmes.
 11. copy the adeptkey.der into the config dir of calibre (~/.config/calibre in debian). Your ADE books imported to calibre will automatically be freed from DRM.

 Kindle and Mobipocket Plugin - K4MobiDeDRM_v04.10_plugin.zip
 ============================================================
 Credit given to The Dark Reverser for the original standalone script. Credit also to the many people who have updated and expanded that script since then.
 Plugin for K4PC, K4Mac, eInk Kindles and Mobipocket.
 This plugin supersedes MobiDeDRM, K4DeDRM, and K4PCDeDRM and K4X plugins. If you install this plugin, those plugins should be removed, as should any earlier versions of this plugin.
 This plugin is meant to remove the DRM from .prc, .mobi, .azw, .azw1, .azw3, .azw4 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 books from those programs.
 Installation
 ------------
 Do **NOT** select "Get plugins to enhance calibre" as this is reserved for "official" calibre plugins, instead select "Change calibre behavior" to go to Calibre's Preferences page.  Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file (K4MobiDeDRM_v04.10_plugin.zip) and click the 'Add' button. Click 'Yes' in the the "Are you sure?" dialog. Click OK in the "Success" dialog.
 Make sure that you delete any old versions of the plugin. They might interfere with the operation of the new one.
 Customization
 -------------
 Highlight the plugin (K4MobiDeDRM under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page.
 If you have an eInk Kindle enter the 16 character serial number (these all begin a "B" or a "9") in the serial numbers field. The easiest way to make sure that you have the serial number right is to copy it from your Amazon account pages (the "Manage Your Devices" page). If you have more than one eInk Kindle, you can enter multiple serial numbers separated by commas.
 If you have Mobipocket books, enter your 8 or 10 digit PID in the Mobipocket PIDs field. If you have more than one PID, separate them with commas.
 These configuration steps are not needed if you only want to decode "Kindle for PC" or "Kindle for Mac" books.

 Linux Systems Only
 -----------------
 If you install Kindle for PC in Wine, the plugin should be able to decode files from that Kindle for PC installation under Wine. You might need to enter a Wine Prefix if it's not already set in your Environment variables. You will need to install Python and PyCrypto under Wine as detailed below. In addition, some people who have successfully used the plugin in this way have commented as follows:
 Here are the instructions for using Kindle for PC on Linux under Wine. (Thank you Eyeless and Pete)
 1. upgrade to very recent versions of Wine; This has been tested with Wine 1.3.15 – 1.3.2X. It may work with earlier versions but no promises. It does not work with wine 1.2.X versions.
 If you have not already installed Kindle for PC under wine, follow steps 2 and 3 otherwise jump to step 4
 2. Some versions of winecfg have a bug in setting the volume serial number, so create a .windows-serial file at root of drive_c to set a proper windows volume serial number (8 digit hex value for unsigned integer).
 cd ~
 cd .wine
 cd drive_c
 echo deadbeef > .windows-serial
 Replace "deadbeef" with whatever hex value you want but I would stay away from the default setting of "ffffffff" which does not seem to work. BTW: deadbeef is itself a valid possible hex value if you want to use it
 3. Only ***after*** setting the volume serial number properly – download and install under wine K4PC version for Windows. Register it and download from your Archive one of your Kindle ebooks. Versions known to work are K4PC 1.7.1 and earlier. Later version may work but no promises.
 FIRST user
 ----------
 Hi everyone, I struggled to get this working on Ubuntu 12.04. Here are the secrets for everyone:
 1. Make sure your Wine installation is set up to be 32 bit. 64 bit is not going to work! To do this, remove your .wine directory (or use a different wineprefix). Then use WINEARCH=win32 winecfg
 2. But wait, you can’t install Kindle yet. It won’t work. You need to do: winetricks -q vcrun2008 or else you’ll get an error: unimplemented function msvcp90.dll .
 3. Now download and install Kindle for PC and download your content as normal.
 4. Now download and install Python 2.7 32 bit for Windows from python.org, 32 bit, install it the usual way, and you can now run the Kindle DRM tools.
 SECOND USER
 -----------
 It took a while to figure out that I needed wine 32 bit, plus Python 27 32 bit, plus the winetricks, to get all this working together but once it’s done, it’s great and I can read my Kindle content on my Nook Color running Cyanogenmod!!!
 Linux Systems Only:
 For all of the following wine installs, use WINEARCH=win32 if you are on x86_64. Also remember that in order to execute a *.msi file, you have to run ‘WINEARCH=win32 wine msiexec /i xxxxx.msi’.
 1. Install Kindle for PC with wine.
 2. Install ActivePython 2.7.x (Windows x86) with wine from here: http://www.activestate.com/activepython/downloads
 3. Install the pycrypto (Windows 32 bit for Python 2.7) module with wine from here: http://www.voidspace.org.uk/python/modules.shtml#pycrypto
 4. Install the K4MobiDeDRM plugin into your _Linux_ Calibre installation
 Now all Kindle books downloaded from Kindle for PC in Wine will be automatically de-DRM’d when they are added to your _Linux_ Calibre. As always, you can troubleshoot problems by adding a book from the terminal using ‘calibredb add xxxx’.
 Or something like that! Hope that helps someone out.
 Installing Python on Windows
 ----------------------------
 I strongly recommend fully installing ActiveState’s Active Python, free Community Edition for Windows (x86) 32 bits. This is a free, full version of the Python.  It comes with some important additional modules that are not included in the bare-bones version from www.python.org unless you choose to install everything.
 1. Download ActivePython 2.7.X for Windows (x86) (or later 2.7 version for Windows (x86) ) from http://www.activestate.com/activepython/downloads. Do not download the ActivePython 2.7.X for Windows (64-bit, x64) verson, even if you are running 64-bit Windows.
 2. When it has finished downloading, run the installer. Accept the default options.
 Installing PyCrypto on Windows
 ------------------------------
 PyCrypto is a set of encryption/decryption routines that work with Python. The sources are freely available, and compiled versions are available from several sources. You must install a version that is for 32-bit Windows and Python 2.7. I recommend the installer linked from Michael Foord’s blog.
 1. Download PyCrypto 2.1 for 32bit Windows and Python 2.7 from http://www.voidspace.org.uk/python/modules.shtml#pycrypto
 2. When it has finished downloading, unzip it. This will produce a file “pycrypto-2.1.0.win32-py2.7.exe”.
 3. Double-click “pycrypto-2.1.0.win32-py2.7.exe” to run it. Accept the default options.

 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

 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.

 eReader PDB2PML - eReaderPDB2PML_v08_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
 ------------
 Do **NOT** select "Get plugins to enhance calibre" as this is reserved for "official" calibre plugins, instead select "Change calibre behavior" to go to Calibre's Preferences page.  Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file  (eReaderPDB2PML_v08_plugin.zip) and click the 'Add' button.  Click 'Yes' in the the "Are you sure?" dialog. Click OK in the "Success" dialog.
 Customization
 -------------
 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
 Troubleshooting
 ---------------
 If you find that it's not working for you (imported ebooks still have DRM), you can save a lot of time and trouble by first deleting the DRMed ebook from calibre and then trying to add the ebook 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. ;)
 On Macintosh only you must first run calibre, open Preferences, open Miscellaneous, and click on the “Install command line tools” button. (On Windows and Linux the command line tools are installed automatically.)
 On Windows, open a terminal/command window. (Start/Run… and then type ‘cmd’ (without the ‘s) as the program to run).
 On Macintosh, open the Terminal application (in your Utilities folder).
 On Linux open a command window. Hopefully all Linux users know how to do this, as I do not.
 You should now have a text-based command-line window open. Also have open the folder containing the ebook to be imported. Make sure that book isn’t already in calibre, and that calibre isn’t running.
 Now type in "calibredb add " (without the " but don’t miss that final space) and now drag the book to be imported onto the window. The full path to the book should be inserted into the command line. Now press the return/enter key. The import routines will run and produce some logging information.
 Now copy the output from the terminal window.
 On Windows, you must use the window menu (little icon at left of window bar) to select all the text and then to copy it.
 On Macintosh and Linux, just use the normal text select and copy commands.

 # Released under the terms of the GNU General Public Licence, version 3 or

 #
 # All credit given to The Dark Reverser for the original standalone script.
 # I had the much easier job of converting it to Calibre a 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) and click the
 # "Customize Plugin" button on Calibre's Preferences->Plugins page.
 # Enter your name and the 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!!
 #
 # Revision history:
 #   0.0.1 - Initial release
 #   0.0.2 - updated to distinguish it from earlier non-openssl version

 <h1>Ignoble Epub DeDRM Plugin</h1>
 <h3>(version 0.2.4)</h3>
 <h3> For additional help read the <a href="http://apprenticealf.wordpress.com/2011/01/17/frequently-asked-questions-about-the-drm-removal-tools/" target="_blank">FAQ</a> on <a href="http://apprenticealf.wordpress.com" target="_blank">Apprentice Alf's Blog</a> and ask questions in the comments section of the <a href="http://apprenticealf.wordpress.com/2012/09/10/drm-removal-tools-for-ebooks/" target="_blank">first post</a>.</h3>
 <p>All credit given to I ♥ Cabbages for the original standalone scripts (I had the much easier job of converting them to a calibre plugin).</p>
 <p>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.</p>
 <p>This help file is always available from within the plugin's customization dialog in calibre (when installed, of course). The "Plugin Help" link can be found in the upper-right portion of the customization dialog.</p> 
 <h3>Installation:</h3>
 <p>Go to calibre's Preferences page.  Do **NOT** select "Get plugins to enhance calibre" as this is reserved for "official" calibre plugins, instead select "Change calibre behavior". Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file  (ignobleepub_v02.3_plugin.zip) and click the 'Add' button. Click 'Yes' in the the "Are you sure?" dialog. Click OK in the "Success" dialog. <b><u>Now restart calibre</u></b>.</p>
 <h3>Configuration:</h3>
 <p>Upon first installing the plugin (or upgrading from a version earlier than 0.2.0), the plugin will be unconfigured. Until you create at least one B&amp;N key&mdash;or migrate your existing key(s)/data from an earlier version of the plugin&mdash;the plugin will not function. When unconfigured (no saved keys)... an error message will occur whenever ePubs are imported to calibre. To eliminate the error message, open the plugin's customization dialog and create/import/migrate a key (or disable/uninstall the plugin). You can get to the plugin's customization dialog by opening calibre's Preferences dialog, and clicking Plugins (under the Advanced section). Once in the Plugin Preferences, expand the "File type plugins" section and look for the "Ignoble Epub DeDRM" plugin. Highlight that plugin and click the "Customize plugin" button.</p>
 <p>If you are upgrading from an earlier version of this plugin and have provided your name(s) and credit card number(s) as part of the old plugin's customization string, you will be prompted to migrate this data to the plugin's new, more secure, key storage method when you open the customization dialog for the first time. If you choose NOT to migrate that data, you will be prompted to save that data as a text file in a location of your choosing. Either way, this plugin will no longer be storing names and credit card numbers in plain sight (or anywhere for that matter) on your computer or in calibre. If you don't choose to migrate OR save the data, that data will be lost. You have been warned!!</p>
 <p>Upon configuring for the first time, you may also be asked if you wish to import your existing *.b64 keyfiles (if you use them) to the plugin's new key storage method. The new plugin no longer looks for keyfiles in calibre's configuration directory, so it's highly recommended that you import any existing keyfiles when prompted ... but you <i>always</i> have the ability to import existing keyfiles anytime you might need/want to.</p>
 <p>If you have upgraded from an earlier version of the plugin, the above instructions may be all you need to do to get the new plugin up and running. Continue reading for new-key generation and existing-key management instructions.</p>
 <h4 style="margin-left: 1.0em;"><u>Creating New Keys:</u></h4>
 <p style="margin-left: 1.0em">On the right-hand side of the plugin's customization dialog, you will see a button with an icon that looks like a green plus sign (+). Clicking this button will open a new dialog for entering the necessary data to generate a new key.</p>
 <ul style="margin-left: 2.0em;">
 <li><b>Unique Key Name:</b> this is a unique name you choose to help you identify the key after it's created. This name will show in the list of configured keys. Choose something that will help you remember the data (name, cc#) it was created with.</i>
 <li style="margin-top: 0.5em;"><b>Your Name:</b> Your name as set in your Barnes & Noble account, My Account page, directly under PERSONAL INFORMATION. It is usually just your first name and last name separated by a space. This name will not be stored anywhere on your computer or in calibre. It will only be used in the creation of the one-way hash/key that's stored in the preferences.</i>
 <li style="margin-top: 0.5em;"><b>Credit Card#:</b> this is the default credit card number that was on file with Barnes & Noble at the time of download of the ebook to be de-DRMed. Nothing fancy here; no dashes or spaces ... just the 16 (15 for American Express) digits. Again... this number will not be stored anywhere on your computer or in calibre. It will only be used in the creation of the one-way hash/key that's stored in the preferences.</i> 
 </ul> 
 <p style="margin-left: 1.0em;">Click the 'OK" button to create and store the generated key. Or Cancel if you didn't want to create a key.</p>
 <h4 style="margin-left: 1.0em;"><u>Deleting Keys:</u></h4>
 <p style="margin-left: 1.0em;">On the right-hand side of the plugin's customization dialog, you will see a button with an icon that looks like a red "X". Clicking this button will delete the highlighted key in the list. You will be prompted once to be sure that's what you truly mean to do. Once gone, it's permanently gone.</p>
 <h4 style="margin-left: 1.0em;"><u>Exporting Keys:</u></h4>
 <p style="margin-left: 1.0em;">On the right-hand side of the plugin's customization dialog, you will see a button with an icon that looks like a computer's hard-drive. Use this button to export the highlighted key to a file (*.b64). Used for backup purposes or to migrate key data to other computers/calibre installations. The dialog will prompt you for a place to save the file.</p>
 <h4 style="margin-left: 1.0em;"><u>Importing Existing Keyfiles:</u></h4>
 <p style="margin-left: 1.0em;">At the bottom-left of the plugin's customization dialog, you will see a button labeled "Import Existing Keyfiles". Use this button to import existing *.b64 keyfiles. Used for migrating keyfiles from older versions of the plugin (or keys generated with the original I &lt;3 Cabbages script), or moving keyfiles from computer to computer, or restoring a backup. Some very basic validation is done to try to avoid overwriting already configured keys with incoming, imported keyfiles with the same base file name, but I'm sure that could be broken if someone tried hard. Just take care when importing.</p>
 <p>Once done creating/importing/exporting/deleting decryption keys; click "OK" to exit the customization dialogue (the cancel button will actually work the same way here ... at this point all data/changes are committed already, so take your pick).</p>
 <h3>Troubleshooting:</h3>
 <p style="margin-top: 0.5em;">If you find that it's not working for you (imported Barnes & Noble 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. ;)</p>
 <p>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.</p>
 <p>Another way to debug (perhaps easier if you're not all that comfortable with command-line stuff) is to launch calibre in debug mode. Open a command prompt (terminal) and type "calibre-debug -g" (again without the quotes). Calibre will launch, and you can can add the problem book(s) using the normal gui method. The debug info will be output to the original command prompt (terminal window). Copy the resulting output and paste it into any online help request you make.</p>
 <p>&nbsp;</p>
 <p>** 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.</p>

 # This plugin is meant to decrypt Barnes & Noble Epubs that are protected

 # 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:
 # Check out the plugin's configuration settings by clicking the "Customize plugin"
 # button when you have the "BnN ePub DeDRM" plugin highlighted (under Preferences->
 # Plugins->File type plugins). Once you have the configuration dialog open, you'll
 # see a Help link on the top right-hand side.

 #!/usr/bin/env python
 # ignobleepub_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 Calibre a 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.
 #
 # 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. 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.
 #
 #
 # Revision history:
 #   0.1.0 - Initial release
 #   0.1.1 - Allow Windows users to make use of openssl if they have it installed.
 #          - Incorporated SomeUpdates zipfix routine.

 """Secret-key encryption algorithms.
 Secret-key encryption algorithms transform plaintext in some way that
 is dependent on a key, producing ciphertext. This transformation can
 easily be reversed, if (and, hopefully, only if) one knows the key.
 The encryption modules here all support the interface described in PEP
 272, "API for Block Encryption Algorithms".
 If you don't know which algorithm to choose, use AES because it's
 standard and has undergone a fair bit of examination.

 #
 # Requires Calibre version 0.7.55 or higher.
 #
 # All credit given to i♥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 one or more
 # 'calibre-adeptkey<n>.der' files and save them in calibre's configuration directory.
 # It will use those files on subsequent runs. If there is already a 'calibre-adeptkey*.der'
 # file 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♥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. Copy 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.

 # Released under the terms of the GNU General Public Licence, version 3 or

 #
 # 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.
