+From Apprentice Alf's Blog
+
+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:
+
+http://pastebin.com/kuKMXXsC
+
+It is not included in the tools archive.

+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_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
+as well get used to it. ;)
+
+Open a command prompt (terminal) and change to the directory where the ebook you're trying to import resides. Then type the command "calibredb add your_ebook.epub". Don't type the quotes and obviously change the 'your_ebook.epub' to whatever the filename of your book is. Copy the resulting output and paste it into any online help request you make.
+
+** Note: the Mac version of Calibre doesn't install the command line tools by default. If you go to the 'Preferences' page and click on the miscellaneous button, you'll see the option to install the command line tools.

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

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

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

+Kindle_4_Mac_Tools version 1.2
+
+Kindle_4_Mac_Tools_v1.2.zip
+http://www.mediafire.com/?8nz9rkg6p9nq23r
+
+
+New in this release:
+ - support to identify Topaz Books and print their PID
+ so that standard Topaz_Tools can be used later if
+ desired (only works with Kindle Version 1.2.0)
+
+Prerequisites:
+
+ - Kindle for Mac.app Version 1.0.0 Beta 1 (27214)
+ (this is the original version)
+
+ or
+
+ Kindle.app Version 1.2.0 (30689)
+ (this is the current version at Amazon)
+
+
+ - XCode Developer Tools **must** be Installed
+ (see your latest Mac OS X Install Disk for the installer)
+
+
+The directions for use are:
+
+1. double-click to unzip the Kindle_4_Mac_Tools_v1.2.zip
+
+2. open the Kindle_4_Mac_Tools folder
+
+3. double-click on K4Munswindle.pyw
+
+In the window that opens:
+
+– hit the first '...' button to locate your Kindle Application
+ if it is not in /Applications
+
+– hit the second '...' button to select an output directory
+ (defaults to your Desktop)
+
+– hit the 'Start' button
+
+After a short delay, your Kindle application should open up automagically
+
+In Kindle for Mac:
+
+ - hit the “Home” button to go home.
+
+ - double-click on ONE of your books.
+ This should open the book.
+
+Once the book you want is open
+
+- hit the “Home” button and then exit the Kindle for Mac application
+
+Once you have exited the Kindle for Mac application you should see one of the following:
+
+ - If the book you selected was a Topaz Book:
+
+ A Warning message will appear in the Conversion Log indicating
+ that the book you opened was Topaz, along with the 8 digit PID
+ needed to convert it using Topaz_Tools
+
+ - If the book you selected was a Mobi book:
+
+ MobiDeDRM will be automagically started in the Conversion Log
+ window and if successful you should find your decoded book in
+ the output directory.

+#!/usr/bin/python
+#
+# This is a python script. You need a Python interpreter to run it.
+# For example, ActiveState Python, which exists for windows.
+#
+# It can run standalone to convert files, or it can be installed as a
+# plugin for Calibre (http://calibre-ebook.com/about) so that
+# importing files with DRM 'Just Works'.
+#
+# To create a Calibre plugin, rename this file so that the filename
+# ends in '_plugin.py', put it into a ZIP file and import that Calibre
+# using its plugin configuration GUI.
+#
+# Changelog
+# 0.01 - Initial version
+# 0.02 - Huffdic compressed books were not properly decrypted
+# 0.03 - Wasn't checking MOBI header length
+# 0.04 - Wasn't sanity checking size of data record
+# 0.05 - It seems that the extra data flags take two bytes not four
+# 0.06 - And that low bit does mean something after all :-)
+# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
+# 0.08 - ...and also not in Mobi header version < 6
+# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
+# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
+# import filter it works when importing unencrypted files.
+# Also now handles encrypted files that don't need a specific PID.
+# 0.11 - use autoflushed stdout and proper return values
+# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
+# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
+# and extra blank lines, converted CR/LF pairs at ends of each line,
+# and other cosmetic fixes.
+# 0.14 - Working out when the extra data flags are present has been problematic
+# Versions 7 through 9 have tried to tweak the conditions, but have been
+# only partially successful. Closer examination of lots of sample
+# files reveals that a confusin has arisen because trailing data entries
+# are not encrypted, but it turns out that the multibyte entries
+# in utf8 file are encrypted. (Although neither kind gets compressed.)
+# This knowledge leads to a simplification of the test for the
+# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
+# 0.15 - Now outputs 'hearbeat', and is also quicker for long files.
+# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.

+- LZskindle4PC is a front end for running skindle that makes it easier for some people who do not like command lines to use it.
+
+- skindle has completely reverse engineered how the book specific PID is generated for Kindle4PC so it can be very useful when new version of Kindle4PC are released and unswindle has not yet been updated. Unfortunately, skindle has some minor bugs that can actually result in corrupted eBooks. No one has yet tracked them down and fixed them. Until they do, use at your own risk.
+
+- unswindle can be used to find the book specific PID but it needs to be updated for each version of Kindle4PC that Amazon releases (and therefore is also useful for Linux users who have Wine). This program “patches” the Kindle4PC executable and therefore is very release specific.
+Unfortunately unswindle v7 the latest, has not been updated to work with the latest version of Kindle for PC. You will need to find one of the older versions of Kindle4PC and prevent later updates in order to use this tool.

+# Changelog
+# 0.01 - Initial version
+# 0.02 - Huffdic compressed books were not properly decrypted
+# 0.03 - Wasn't checking MOBI header length
+# 0.04 - Wasn't sanity checking size of data record
+# 0.05 - It seems that the extra data flags take two bytes not four
+# 0.06 - And that low bit does mean something after all :-)
+# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
+# 0.08 - ...and also not in Mobi header version < 6
+# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
+# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
+# import filter it works when importing unencrypted files.
+# Also now handles encrypted files that don't need a specific PID.
+# 0.11 - use autoflushed stdout and proper return values
+# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
+# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
+# and extra blank lines, converted CR/LF pairs at ends of each line,
+# and other cosmetic fixes.
+# 0.14 - Working out when the extra data flags are present has been problematic
+# Versions 7 through 9 have tried to tweak the conditions, but have been
+# only partially successful. Closer examination of lots of sample
+# files reveals that a confusin has arisen because trailing data entries
+# are not encrypted, but it turns out that the multibyte entries
+# in utf8 file are encrypted. (Although neither kind gets compressed.)
+# This knowledge leads to a simplification of the test for the
+# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
+# 0.15 - Now outputs 'hearbeat', and is also quicker for long files.
+# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.

+Readme.txt
+
+From Apprentice Alf's Blog:
+
+When Amazon released Kindle for PC, there was a lot of interest in finding the PID used by an installed copy. Unfortunately, it turned out that Amazon had taken the opportunity to increase the complexity of the DRM applied to ebooks downloaded for use with Kindle for PC. In short, every book has its own PID.
+
+The current best method is a script called K4PCDeDRM.py, which takes code from several previous tools and puts them together, giving a one-script solution to removing the DRM that is not dependent on the exact version of the Kindle for PC software.
+
+To use this script requires Python Version 2.X 32 bit version. On Windows, we recommend downloading ActiveState's ActivePython for Windows (Version 2.X NOT 3.X (32bit).
+
+We strongly recommend that at the moment people with Kindle for Windows should use K4PCDeDRM.pyw instead of any of the other methods (skindle, unswindle).
+
+K4PCDeDRM is available in the large archive mentioned in the first post.
+
+To run it simply completely extract the tools archive and open the Kindle_4_PC_Tools. Then double-click on K4PCDeDRM.pyw to run the gui version.
+
+Please note, the tools archive must be on the same machine in the same account as the Kindle for PC application for things to work.
+
+FYI:
+Books downloaded to Kindle for PC are stored in a folder called “My Kindle Content” in the current user’s home folder.
+
+IMPORTANT: There are two kinds of Kindle ebooks. Mobipocket and Topaz. For Topaz books it’s really necessary to use the Topaz specific tools mentioned in this post which not only remove the DRM but also convert the Topaz file into a format that can be converted into other formats.

+Kindle for iPhone, iPod Touch, iPad
+
+
+The Kindle application for iOS (iPhone/iPod Touch/iPad) uses a PID derived from the serial number of the iPhone/iPod Touch/iPad. Kindlepid.py is a python script that turns the serial number into the equivalent PID, which can then be used with the MobiDeDRM script.
+
+So, to remove the DRM from (Mobipocket) Kindle books downloaded to your iPhone/iPodTouch/iPad, you’ll need the latest toolsvx.x.zip archive and
+some way to extract the book files from the backup of your device on your computer. There are several free tools around to do this.
+
+Double-click on KindlePID.pyw to get your device’s PID, then use the extractor to get your book files, then double-click on MobiDeDRM.pyw with the PID and the files to get Drm-free versions of your books.
+
+Kindlefix gives you another way to use the PID generated by kindlepid. Some ebook stores and libraries will accept the PIDs generated by kindlepid (some won’t), and you can then download ebooks from the store or library encrypted to work with your Kindle. Except they don’t. There’s a flag byte set in encrypted Kindle ebooks, and Kindles and the Kindle app won’t read encrypted mobipocket ebooks unless that flag is set. Kindlefix will set that flag for you. If your library have Mobipocket ebooks to lend and will accept your Kindle’s PID, you can now check out library ebooks, run kindlefix on them, and then read them on your Kindle, and when your loan period ends, they’ll automatically become unreadable.
+
+To extract the files from your iPod Touch (not archived Kindle ebooks, but ones actually on your iPod Touch) it’s necessary to first do a back-up of the iPod Touch using iTunes. That creates a backup file on your Mac, and you can then extract the Mobipocket files from that using iPhone/ipod Touch Backup Extractor – free software from here: http://supercrazyawesome.com/
+
+Ok, so that will get your the .azw Kindle Mobipocket files.
+
+Now you need the PID used to encrypt them. To get that you’ll need your iPod Touch UDID number – you can find it in iTunes when your iPod Touch is connected in the Summary page – click on the serial number and it changes to the (40 digit!) UDID.
+
+And then you need to double-click the KindlePID.pyw script and enter your 40 digit UDID in the window and hit "Start".
+
+ and you should get back a response something like:
+
+Mobipocket PID calculator for Amazon Kindle. Copyright (c) 2007, 2009 Igor Skochinsky
+iPhone serial number (UDID) detected
+Mobipocked PID for iPhone serial# FOURTYDIGITUDIDNUMBERGIVENHERE is TENDIGITPID
+
+which gives you the PID to be used with MobiDeDRM to de-drm the files you extracted.
+
+All of these scripts are gui python programs. Python 2.X (32 bit) is already installed in Mac OSX and Linux. We recommend ActiveState's Active Python Version 2.X (32 bit) for Windows users.

+The Topaz Tools only work for "Kindle for PC" books, and original standalone Kindles that have never been updated to firmware 2.5 or later, Kindle for iPhone/iPad/iPodTouch (where the PID is known) and Kindle for Mac (with the PID provided by the Kindle_4_Mac_Tools).
+
+For Topaz:
+
+1. Make sure you have Python 2.X installed (32 bit) and properly set as part of your SYSTEM PATH environment variable (On Windows I recommend ActivePython. See their web pages for instructions on how to install and how to properly set your PATH). On Mac OSX 10.6 everything you need is already installed.
+
+2. Simply download the latest tools_vX.X.zip file (see the comments after the first post on this blog) and extract the entire archive. Do not move or rename anything after extracting the entire archive.
+
+3. move to tools\Topaz_Tools\
+
+4. If you have an old Kindle (never updated to 2.5 or later) or an iPod, iPhone, or iPad or Kindle for Mac and you know your PID then double-click on the following:
+
+TopazExtract_iPhone_iPad_K4M.pyw
+
+If you have Kindle for PC (and no Kindle for Mac will NOT work here) then instead double-click on the following:
+
+TopazExtract_Kindle4PC.pyw
+
+Hit the first “…” button to select the Topaz book with DRM that you want to convert
+
+Hit the second “…” to select an entirely new directory to extract the many book pieces into
+
+And add info for your PID (or extra PIDs) if needed (should not be needed for Kindle For PC).
+
+Hit the Start button
+
+3. Next double-click on TopazFiles2SVG.pyw
+(use the “…” button to select the new directory you created from the previous step, and hit Start)
+
+4. Finally double-click on TopazFiles2HTML.pyw
+(use the “…” button to slect the new directory you created in step 2, and hit Start)
+
+5. After all of this you should have book.html inside the directory you created with its own image directory and css style sheet. This file is created from the ocr that is done by Amazon and stored in the Topaz file. All errors belong to Amazon.
+
+Inside of that same directory, you should have an svg directory which has an exact image of each page of the book. To see it, simply open the .xhtml page which has the embedded svg image in a good browser (Firefox, Safari, etc)
+
+If you run into any problems – and there can be problems because the format has not been completely reversed engineered, simply copy the entire contents of the Conversion Log window and paste them in a post here or on the Dark Reverser’s New Blog and I will find it and try to help

+From Apprentice Alf's Blog
+
+Barnes & Noble/Fictionwise eReader, .pdb
+
+Barnes & Noble’s .pdb eReader format is one of the survivors from the early days of ebooks. Internally, text is marked up in PML – Palm Markup Language. This makes conversion to other formats more difficult.
+
+Barnes and Noble .pdb ebooks use a form of Social DRM which requires information on your Credit Card Number (last 8 digits only) and the Name on the Credit card to unencrypt the book that was purchased with that credit card.
+
+There are three scripts used to decrypt and convert eReader ebooks.
+
+The first, eReaderPDB2PML.pyw removes the DRM and extracts the PML and images from the ebook into a folder. It’s then possible to use the free DropBook (available for Mac or Windows) to compile the PML back into a DRM-free eReader file.
+
+The second script, Pml2HTML.pyw, converts the PML file extracted by the first script into xhtml, which can then be converted into your preferred ebook format with a variety of tools.
+
+The last script is eReaderPDB2PMLZ.pyw and it removes the DRM and extracts the PML and images from the ebook into a zip archive that can be directly imported into Calibre.
+
+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.
+
+Simply double-click to launch these applications and follow along.
