-Adobe Adept ePub and PDF, .epub, .pdf
-
-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.
-
-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.
-
-
-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:

+Ignoble Epub DeDRM - ignobleepub_v02.2_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:
+
+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_v02.2_plugin.zip) and click the 'Add' button. Click 'Yes' in the the "Are you sure?" dialog. Click OK in the "Success" dialog.
+
+
+Configuration:
+
+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.
+
+Paste the information into a comment at my blog, describing your problem.

+Inept Epub DeDRM - ineptepub_v01.9_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:
+
+Go to Calibre's Preferences page. Do **NOT** select "Get plugins to enhance calibre" as this is reserved for "official" calibre plugins, instead select "Cahnge calibre behavior". Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file (ineptepub_v01.9_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). 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.

+K4MobiDeDRM_v04.6_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.
+
+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 those types of books.
+
+
+Installation:
+
+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 (K4MobiDeDRM_v04.6_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.
+
+
+Configuration:
+
+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") 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.

+#
+# 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 are for DOC compressed
+#         files, but they are not for HUFF/CDIC compress files!
+#  0.30 - Modified interface slightly to work better with new calibre plugin style
+#  0.31 - The multibyte encrytion info is true for version 7 files too.
+#  0.32 - Added support for "Print Replica" Kindle ebooks
+#  0.33 - Performance improvements for large files (concatenation)
+#  0.34 - Performance improvements in decryption (libalfcrypto)
+#  0.35 - add interface to get mobi_version
+#  0.36 - fixed problem with TEXtREAd and getBookTitle interface
+#  0.37 - Fixed double announcement for stand-alone operation

-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.

-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:

-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.

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.

Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file  (eReaderPDB2PML_v07_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:
+
+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.
+
+Paste the information into a comment at my blog, describing your problem.

-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!!)
-
-Troubleshooting:
-If you find that it's not working for you (imported pdb's are not converted to pmlz format), you can save a lot of time and trouble by trying to add the pdb 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.pdb". Don't type the quotes and obviously change the 'your_ebook.pdb' 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.

+<h1>Ignoble Epub DeDRM Plugin</h1>
+<h3>(version 0.2.3)</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 &lt;3 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>

-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.

-
-# ignobleepub_v01_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.
-#

-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.

-"""Hashing algorithms
-
-Hash functions take arbitrary strings as input, and produce an output
-of fixed size that is dependent on the input; it should never be
-possible to derive the input data given only the hash function's
-output.  Hash functions can be used simply as a checksum, or, in
-association with a public-key algorithm, can be used to implement
-digital signatures.
-
-The hashing modules here all support the interface described in PEP
-247, "API for Cryptographic Hash Functions".
-
-Submodules:
-Crypto.Hash.HMAC          RFC 2104: Keyed-Hashing for Message Authentication
-Crypto.Hash.MD2
-Crypto.Hash.MD4
-Crypto.Hash.MD5
-Crypto.Hash.RIPEMD160
