-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.

-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.

-# ***NOTE*** Calibre and K4PC must be installed on the same windows machine

-#
-# To create a Calibre plugin, rename this file so that the filename

-# 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.

-
-This plugin is meant to Kindle for PC azw ebooks that are protected
-with Amazon's Mobi based encryption. It is meant to function without having to install any dependencies... other than having both Calibre installed and Kindle for PC on the same machine, of course. 
-
-Installation:
-
-Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file  (K4PCDeDRM_X.XX_plugin.zip) and click the 'Add' button. you're done.

-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.

-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.

-This work is based on the current mobidedrm.py code.
-
-This plugin is meant to Mobipocket and Kindle ebooks that are protected
-with Amazon's Mobi based encryption. It is meant to function without having to install any dependencies... other than having both Calibre installed.  You must know the PID orf the device you are using or the book specific PID to use this plugin.
-
-Installation:
-
-Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file  (MobiDeDRM_X.XX_plugin.zip) and click the 'Add' button.

-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.

-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.

-# ineptepub_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 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.

+# Overview
+## What's this repository all about?
+Providing free open source tools to remove DRM from your ebooks.
+
+## What's DRM?
+DRM ("Digital Rights Management") is a way of using encryption to tie the books you've bought to a specific device or to a particular piece of software.
+
+## Why would I want to remove DRM from my ebooks?
+When your ebooks have DRM you are unable to convert the ebook from one format to another (e.g. Kindle KF8 to Kobo ePub), so you are restricted in the range of ebook stores you can use. DRM also allows publishers to restrict what you can do with the ebook you've bought, e.g. preventing the use of text-to-speech software. Longer term, you can never be sure that you'll be able to come back and re-read your ebooks if they have DRM, even if you save back-up copies.
+
+## So how can I remove DRM from my ebooks?
+Just download and use these tools, that's all! Uh, almost. There are a few, uh, provisos, a, a couple of quid pro quos. 
+
+* The tools don't work on all ebooks. For example, they don't work on any ebooks from Apple's iBooks store.
+* You must own the ebook - the tools won't work on library ebooks or rented ebooks or books from a friend.
+* You must not use these tools to give your ebooks to a hundred of your closest friends. Or to a million strangers. Authors need to sell books to be able to write more books. Don't be mean to the authors.
+* Do NOT use Adobe Digital Editions 3.0 or later to download your ePubs. ADE 3.0 and later might use a new encryption scheme that the tools can't handle. While major ebook stores aren't using the new scheme yet, using ADE 2.0.1 will ensure that your ebooks are downloaded using the old scheme. Once a book has been downloaded with the new scheme, it's IMPOSSIBLE to re-download using the old scheme (without buying it again).
+
+But otherwise, if your ebook is from Amazon, Kobo, Barnes & Noble or any of the ebook stores selling ebooks compatible with Adobe Digital Editions 2.0.1, you should be able to remove the DRM that's been applied to your ebooks.
+
+### A Recent Change to Kindle for PC/Kindle for Mac
+Starting with version 1.19, Kindle for PC/Mac uses Amazon's new KFX format which these tools can't handle. There are two options to get the older formats that the tools can decrypt. Either stick with version 1.17 or earlier, or modify the executable by changing a file name.
+
+Version 1.17 of Kindle is are no longer available directly from Amazon, so you will need to search for the proper file name and find it on a third party site. The name is "KindleForPC-installer-1.17.44170.exe" for PC and "KindleForMac-44182.dmg" for Mac.
+Verify the one of the following cryptographic hash values, using software of your choice, before installing the downloaded file in order to avoid viruses. If the hash does not match, delete the downloaded file and try again from another site.
+Kindle for PC:
+MD-5: 53F793B562F4823721AA47D7DE099869
+SHA-1: 73C404D719F0DD8D4AE1C2C96612B095D6C86255
+SHA-256: 14E0F0053F1276C0C7C446892DC170344F707FBFE99B695176 2C120144163200
+Kindle for Mac:
+MD-5: E7E36D5369E1F3CF1D28E5D9115DF15F
+SHA-1: 7AB9A86B954CB23D622BD79E3257F8E2182D791C
+SHA-256: 28DC21246A9C7CDEDD2D6F0F4082E6BF7EF9DB9CE9D485548E 8A9E1D19EAE2AC. 
+
+You will need to go to the preferences and uncheck the auto update checkbox. Then download and install 1.17 over the top of the 1.19 installation. You'll also need to delete the KFX folders from your My Kindle Content folder.
+
+A second possible solution is to use 1.19 or later, but disable KFX by renaming or disabling a necessary component of the application. This may or may not work on versions after 1.20. In a command window, enter the following commands when Kindle for PC/Mac is not running:
+
+#### Windows
+ren %localappdata%\Amazon\Kindle\application\renderer-test.exe renderer-test.xxx
+
+PC Note: The renderer-test program may be in a different location in some Kindle for PC installations. If the rename command fails look in other folders, such as C:\Program Files\Amazon\Kindle.
+
+#### Macintosh
+chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test
+
+Mac Note: If the chmod command fails with a permission error try again using sudo before chmod - sudo chmod [...]
+
+After restarting the Kindle program any books previously downloaded in KFX format will no longer open. You will need to remove them from your device and re-download them. All future downloads will use the older Kindle formats instead of KFX although they will continue to be placed in one individual subdirectory per book.
+
+#### Another Note on KFX
+It now possible, but not easy, to convert books from KFX to other formats in calibre by installing the optional KFX Input plugin. The lack of automatic DRM removal makes this process difficult so it is not recommended unless there is no other alternative, such as for Indic language books only available in KFX. There is a windows-only KFX DRM rmeoval program in the repository, but not yet integrated into the tools.
+
+#### Thanks
+Thanks to jhowell for his investigations into KFX format and workarounds. Some of these instructions are from [his thread on the subject](https://www.mobileread.com/forums/showthread.php?t=283371) at MobileRead.
+
+## Where can I get the latest version of these free DRM removal tools?
+Right here at github. Just go to the [releases page](https://github.com/apprenticeharper/DeDRM_tools/releases) and download the latest zip archive of the tools, named DeDRM\_tools\_X.X.X.zip, where X.X.X is the version number. You do not need to download the source code archive.
+
+## I've downloaded the tools archive. Now what?
+First, unzip the archive. You should now have a DeDRM folder containing several other folders and a ReadMe\_First.txt file. Please read the ReadMe\_First file! That will explain what the folders are, and you'll be able to work out which of the tools you need.
+
+## That's a big complicated ReadMe file! Isn't there a quick guide?
+Install calibre. Install the DeDRM\_plugin in calibre. Install the Obok\_plugin in calibre. Restart calibre. In the DeDRM_plugin customisation dialog add in any E-Ink Kindle serial numbers and your B&N account email address and password. Remember that the plugin only tries to remove DRM when ebooks are imported.
+
+# Installing the Tools
+## The calibre plugin
+### I am trying to install the calibre plugin, but calibre says "ERROR: Unhandled exception: InvalidPlugin: The plugin in u’[path]DeDRM\_tools\_6.5.3.zip’ is invalid. It does not contain a top-level \_\_init\_\_.py file"
+You are trying to add the tools archive (e.g. DeDRM\_tools\_6.5.3.zip) instead of the plugin. The tools archive is not the plugin. It is a collection of DRM removal tools which includes the plugin. You must unzip the archive, and install the calibre plugin (DeDRM\_plugin.zip) from a folder called “DeDRM\_calibre_plugin” in the unzipped archive.
+
+### I’ve unzipped the tools archive, but I can’t find the calibre plugin when I try to add them to calibre. I use Windows.
+You should select the zip file that is in the “DeDRM\_calibre\_plugin” folder, not any files inside the plugin’s zip archive. Make sure you are selecting from the folder that you created when you unzipped the tools archive and not selecting a file inside the still-zipped tools archive.
+
+(The problem is that Windows will allow apps to browse inside zip archives without needing to unzip them first. If there are zip archives inside the main zip archives, Windows will show them as unzipped as well. So what happens is people will unzip the DeDRM\_tools\_X.X.X.zip to a folder, but when using calibre they will actually navigate to the still zipped file by mistake and cannot tell they have done so because they do not have file extensions showing. So to the unwary Windows user, it appears that the zip archive was unzipped and that everything inside it was unzipped as well so there is no way to install the plugins.
+
+We strongly recommend renaming the DeDRM\_tools\_X.X.X.zip archive (after extracting its contents) to DeDRM\_tools\_X.X.X_archive.zip. If you do that, you are less likely to navigate to the wrong location from inside calibre.)
+
+## The Windows Application
+### I've installed ActiveState Python and PyCrypto, but the Windows application won't run. What have I done wrong?
+Nothing. There's a bug in the some older ActiveState Python Windows installers that puts the Tcl code in the wrong place. See [this comment of mine at ActiveState community](https://community.activestate.com/node/19090). Just move the Tcl code to the correct place manually and the Windows app should run.
+
+## The Macintosh Application
+### I can't open the Macintosh Application. Some message about it not being signed or something.
+Try right-clicking and select open. That might give you the option to open it anyway. Otherwise you'll need to change your security settings to allow unsigned applications to run. You can probably change these back after running it for the first time.
+
+### I can't open the Macintosh Application at all. I get 'The aplication "DeDRM" can't be opened'
+Some unzip applications do not respect the execution bit setting. Try unzipping the main tools archive using the built-in Mac unzip utility.
+
+### I can't open the Macintosh Application at all. I get 'spawn_via_launchd() failed, errno=111'
+There seems to be a bug in Apple's launch services. Try using the free [Maintenance utility](https://www.titanium-software.fr/en/maintenance.html) from Titanium Software to clear the launch cache and database.
+
+# Using the Tools
+## I can’t get the tools to work on my rented or library ebooks.
+The tools are not designed to remove DRM from rented or library ebooks.
+
+## I've unzipped the tools, but what are all the different files, and how do I use them?
+Read the ReadMe_First.txt file and then the ReadMe files included in the tools folder(s) you're interested in. That's what they're for.
+
+## I have installed the calibre plugin, but my books still have DRM. When I try to view or convert my books, calibre says they have DRM.
+DRM only gets removed when an ebook is imported into calibre. Also, if the book is already in calibre, by default calibre will discard the newly imported file. You can change this in calibre's Adding books preferences page (Automerge..../Overwrite....), so that newly imported files overwrite existing ebook formats. Then just re-import your books and the DRM-free versions will overwrite the DRMed versions while retaining your books' metadata.
+
+## I have installed the calibre plugin or I am trying to use one of the other tools, but I don’t know where my ebooks are stored.
+Your ebooks are stored on your computer or on your ebook reader. You need to find them to be able to remove the DRM. If they are on your reader, you should be able to locate them easily. On your computer it’s not so obvious. Here are the default locations.
+
+### Macintosh
+Navigating from your home folder,
+
+Kindle for Mac ebooks are in either Library/Application Support/Kindle/My Kindle Content or Documents/My Kindle Content or Library/Containers/com.amazon.Kindle/Data/Library/Application Support/Kindle/My Kindle Content, depending on your version of Kindle for Mac.
+
+Adobe Digital Editions ebooks are in Documents/Digital Editions
+
+### Windows
+Navigating from your "Documents" folder ("My Documents" folder, pre-Windows 7)
+
+Kindle for PC ebooks are in My Kindle Content
+
+Adobe Digital Editions ebooks are in My Digital Editions
+
+
+## I have installed the calibre plugin, and the book is not already in calibre, but the DRM does not get removed.
+You must use the exact file that is used by your ebook reading software or hardware. See the previous question on where to find your ebook files. Do not use an old copy you have that you can no longer read.
+If you cannot read the ebook on your current device or installed software, the tools will certainly not be able to remove the DRM. Download a fresh copy that does work with your current device or installed software.
+
+## I have installed the calibre plugin, and the book is not already in calibre, but the DRM does not get removed. It is a Kindle book.
+If you are on Windows 8 and using the Windows 8 AppStore Kindle app, you must download and install the Kindle for PC application directly from the Amazon website. The tools do not work with the Windows 8 AppStore Kindle app.
+
+If this book is from an eInk Kindle (e.g. Paperwhite), you must enter the serial number into the configuration dialog. The serial number is sixteen characters long, and is case-sensitive.
+
+If this book is from Kindle for Mac or Kindle for PC, you must have the Kindle Software installed on the same computer and user account as your copy of calibre.
+
+If this book is from Kindle for Mac or Kindle for PC, you must be using version 1.17 or below, see note at top of this file.
+
+If the book is from Kindle for PC or Kindle for Mac and you think you are doing everything right, and you are getting this message, it is possible that the files containing the encryption key aren’t quite in the format the tools expect. To try to fix this:
+
+1. Deregister Kindle for PC(Mac) from your Amazon account.
+1. Uninstall Kindle for PC(Mac)
+1. Delete the Kindle for PC(Mac) preferences
+    * PC: Delete the directory [home folder]\AppData\Local\Amazon (it might be hidden) and [home folder]\My Documents\My Kindle Content
+    * Mac: Delete the directory [home folder]/Library/Application Support/Kindle/and/or [home folder]/Library/Containers/com.amazon.Kindle/Data/Library/Application Support/Kindle/ (one or both may be present and should be deleted)
+1. Reinstall Kindle for PC(Mac) version 1.17 or earlier (see above for download links).
+1. Re-register Kindle for PC(Mac) with your Amazon account
+1. Download the ebook again. Do not use the files you have downloaded previously.
+
+## Some of my books had their DRM removed, but some still say that they have DRM and will not convert.
+There are several possible reasons why only some books get their DRM removed.
+* You still don’t have the DRM removal tools working correctly, but some of your books didn’t have DRM in the first place.
+* Kindle only: It is a Topaz format book and contains some coding that the tools do not understand. You will need to get a log of the DeDRM attempt, and then create a [new issue at Apprentice Harper's github repository](https://github.com/apprenticeharper/DeDRM_tools/issues/), attaching the book and the log, so that the tools can be updated.
+
+If you are still having problems with particular books, you will need to create a log of the DRM removal attempt for one of the problem books, and post that in a comment at Apprentice Alf's blog or in a new issue at Apprentice Harper's github repository.
+
+## My Kindle book has imported and the DRM has been removed, but all the pictures are gone.
+Most likely, this is a book downloaded from Amazon directly to an eInk Kindle (e.g. Paperwhite). Unfortunately, the pictures are probably in a .azw6 file that the tools don't understand. You must download the book manually from Amazon's web site "For transfer via USB" to your Kindle. When you download the eboook in this manner, Amazon will package the pictures in the with text in a single file that the tools will be able to import successfully.
+
+## My Kindle book has imported, but it's showing up as an AZW4 format. Conversions take a long time and/or are very poor.
+You have found a Print Replica Kindle ebook. This is a PDF in a Kindle wrapper. Now the DRM has been removed, you can extract the PDF from the wrapper using the KindleUnpack plugin. Conversion of PDFs rarely gives good results.
+
+## The tools can't see an ebook that was downloaded directly to my eInk kindle, although it's definitely there, and I can read it on the Kindle. I can't even try to import it.
+Mostly likely, this is a book downloaded from Amazon directly to one of the newer eInk Kindles (e.g. Paperwhite). Unfortunately, it is probably in a new multi-file KFX format that the tools don't understand. You must download the book manually from Amazon's web site "For transfer via USB" to your Kindle. When you download the ebook in this manner, Amazon will send a single KF8-format file that the tools will be able to import successfully.
+
+## Do the tools work on books from Kobo?
+If you use the Kobo desktop application for Mac or PC, install the obok plugin. This will import and remove the DRM from your Kobo books, and is the easiest method for Kobo ebooks.
+
+## I registered Adobe Digital Editions 3.0 or later with an Adobe ID before downloading, but my epub or PDF still has DRM.
+Adobe introduced a new DRM scheme with ADE 3.0 and later. Install ADE 2.0.1 and register with the same Adobe ID. If you can't open your book in ADE 2.01, then you have a book with the new DRM scheme. These tools can't help. You can avoid the new DRM scheme by always downloading your ebooks with ADE 2.0.1. Some retailers will require ADE 3.0 or later, in which case you won't be able to download with ADE 2.0.1.
+
+## The DRM wasn't removed and the log says "Failed to decrypt with error: Cannot decode library or rented ebooks." What now?
+You're trying to remove the DRM from an ebook that's only on loan to you. No help will be given to remove DRM from such ebooks. If you think that you have received this message for a book you own, please create an issue at github, or comment at the blog.
+
+## I cannot solve my problem with the DeDRM plugin, and now I need to ‘post a log’. How do I do that?
+Remove the DRMed book from calibre. Click the Preferences drop-down menu and choose 'Restart in debug mode'. Once calibre has re-started, import the problem ebook. Now close calibre. A log will appear that you can copy and paste into a comment at Apprentice Alf's blog, or into a new issue at Apprentice Harper's github repository.
+
+## I cannot solve my problem with the Macintosh DeDRM application, and now I need to ‘post a log’. How do I do that?
+The Macintosh DeDRM application creates a log file on your desktop every time it is run. After unsuccessfully removing DRM from one ebook, copy the contents of the log file (it is a simple text file) and paste it into your comment at Apprentice Alf's blog or in a new issue at Apprentice Harper's github repository.
+
+## I cannot solve my problem with the Windows DeDRM application, and now I need to ‘post a log’. How do I do that?
+The Windows DeDRM application creates a log file in your home directory (C:\Users\[username]) every time it is run. After unsuccessfully removing DRM from one ebook, copy the contents of the log file (it is a simple text file) and paste it into your comment at Apprentice Alf's blog or in a new issue at Apprentice Harper's github repository.
+
+
+# General Questions
+
+## Once the DRM has been removed, is there any trace of my personal identity left in the ebook?
+The tools only remove the DRM. No attempt is made to remove any personally identifying information.
+
+## What do some of my Kindle ebooks import as HTMLZ format in calibre?
+Most Amazon Kindle ebooks are Mobipocket format ebooks, or the new KF8 format. However, some are in a format known as Topaz. The Topaz format is only used by Amazon. A Topaz ebook is a collections of glyphs and their positions on each page tagged with some additional information from that page including OCRed text (Optical Character Recognition generated Text) to allow searching, and some additional layout information. Each page of a Topaz ebook is effectively a description of an image of that page. To convert a Topaz ebook to another format is not easy as there is not a one-to-one mapping between glyphs and characters/fonts. To account for this, two different formats are generated by the DRM removal software. The first is an html description built from the OCRtext and images stored in the Topaz file (HTMLZ). This format is easily reflowed but may suffer from typical OCRtext errors including typos, garbled text, missing italics, missing bolds, etc. The second format uses the glyph and position information to create an accurate scalable vector graphics (SVG) image of each page of the book that can be viewed in web browsers that support svg images (Safari, Firefox 4 or later, etc). Additional conversion software can be used to convert these SVG images to an image only PDF file. The DeDRM calibre plugin only imports the HTMLZ versions of the Topaz ebook. The html version can be manually cleaned up and spell checked and then converted using Sigil/calibre to epubs, mobi ebooks, and etc.
+
+## Are the tools open source? How can I be sure they are safe and not a trojan horse?
+All the DRM removal tools hosted here are almost entirely scripts of one kind or another: Python, Applescript or Windows Batch files. So they are inherently open source, and open to inspection by everyone who downloads them.
+
+There are some optional shared libraries (`*.dll`, `*.dylib`, and `*.so`) included for performance. The source for any compiled pieces are provided within `alfcrypto_src.zip`. If this is a concern either delete the binary files or manually rebuild them.
+
+## What ebooks do these tools work on?
+The tools linked from this blog remove DRM from PDF, ePub, kePub (Kobo), eReader, Kindle (Mobipocket, KF8, Print Replica and Topaz) format ebooks using Adobe Adept, Barnes & Noble, Amazon, Kobo and eReader DRM schemes.
+
+Note these tools do NOT ‘crack’ the DRM. They simply allow the book’s owner to use the encryption key information already stored someplace on their computer or device to decrypt the ebook in the same manner the official ebook reading software uses.
+
+## Why don’t the tools work with Kindle Fire ebooks?
+Because no-one's found out how to remove the DRM from ebooks from Kindle Fire devices yet. The workaround is to install Kindle for PC or Kindle for Mac and use books from there instead.
+
+## Why don't the tools work with Kindle for iOS ebooks?
+Amazon changed the way the key was generated for Kindle for iOS books, and the tools can no longer find the key. The workaround is to install Kindle for PC or Kindle for Mac and use books from there instead.
+
+## Why don't the tools work with Kindle for Android ebooks?
+Amazon turned off backup for Kindle for Android, so the tools can no longer find the key. The workaround is to install Kindle for PC or Kindle for Mac and use books from there instead.
+
+## Why don't the tools work on books from the Apple iBooks Store?
+Apple regularly change the details of their DRM and so the tools in the main tools archive will not work with these ebooks. Apple’s Fairplay DRM scheme can be removed using Requiem if the appropriate version of iTunes can still be installed and used. See the post Apple and ebooks: iBookstore DRM and how to remove it at Apprentice Alf's blog for more details.
+
+## I’ve got the tools archive and I’ve read all the FAQs but I still can’t install the tools and/or the DRM removal doesn’t work
+* Read the ReadMe_First.txt file in the top level of the tools archive
+* Read the ReadMe file in the folder of the tools you want to use.
+* If you still can’t remove the DRM, ask in the comments section of Apprentice Alf's blog or create a new issue at Apprentice Harper's github repository, reporting the error as precisely as you can, what platform you use, what tool you have tried, what errors you get, and what versions you are using. If the problem happens when running one of the tools, post a log (see previous questions on how to do this).
+
+## Who wrote these scripts?
+The authors tend to identify themselves only by pseudonyms:
+* The Adobe Adept and Barnes & Noble scripts were created by i♥cabbages
+* The Amazon Mobipocket and eReader scripts were created by The Dark Reverser
+* The Amazon K4PC DRM/format was further decoded by Bart Simpson aka Skindle
+* The Amazon K4 Mobi tool was created by by some_updates, mdlnx and others
+* The Amazon Topaz DRM removal script was created by CMBDTC
+* The Amazon Topaz format conversion was created by some_updates, clarknova, and Bart Simpson
+* The DeDRM all-in-one AppleScript application was created by Apprentice Alf
+* The DeDRM all-in-one Python application was created by some_updates
+* The DeDRM all-in-one calibre plugins was created by Apprentice Alf
+* The Scuolabooks tool was created by Hex
+* The Microsoft code was created by drs
+* The Apple DRM removal tool was created by Brahms
+
+Since the original versions of the scripts and programs were released, various people have helped to maintain and improve them.

-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.

-# 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.

-LZskindle4PCv1_1    The Lazy skindle program for those who are typing impared
-
-To setup:
-
-1.  Create a new folder:   example C:\skindle
-
-2.  Place LZskindle4PCv1_1.exe and skindle.exe in this folder.
-
-3.  Create 2 subfolders:    C:\skindle\input 
-    and                     C:\skindle\output
-
-
-To run:
-
-1.  Copy the book(s) you wish to remove DRM from into the input directory 
-(leave the originals in my kindle folder).
-
-2.  Double click on LZskindle4PCv1_0.exe
-
-3.  A DOS window will open and will show skindle being called for 
-each book in the input directory.
-
-4.  The books with the DRM removed will now be in the output directory.
-
-Rev1_1
-
-fixed program to allow any file extension.  My testing indicates that 
-skindle does not care what file extension a file has.  If it is a file type
-that it can convert it will.  If the file is not compatible it will close
-and give an unknown file type message.
-
-Rev1_0
-
-If the program is run with no files in the input directory you will get a 
-<EFBFBD>File not Found<6E> error and the program will terminate.
-
-PLEASE USE ONLY FOR YOUR PERSONAL USE <20> ON BOOKS YOU PAID FOR!!
-
-This program is provided to allow you to archive your library in a format that 
-will outlast the kindle.  Technology moves on and you should not have to reinvest 
-in an entire new library when the Kindle is obsolete.  Please do not use this program 
-for piracy.

-Ezskindle4PC.exe 
-
-This executable program makes using skindle easier for people using Windows PC<50>s.
-
-I do not know if it will work under any other operating system, however, I have included 
-the source code should anyone want to port it into other operating systems.
-
-To use this program:
-
-1. Copy the ezskindle4PC.exe into the same directory with the skindle files.
-2. Copy the kindle book into the same directory.
-3. double click the EZskindle4PCv1_0.exe file.
-a. A DOS window will open and you will be asked for the name of the file you want to work with.
-4. Type in the book<6F>s file name.  (it will look something like B000WCTBTA_EBOK.prc)
-5. The program will then check if it is a Topaz file and then create the output file name using the 
-first part of the input file name. It will use <20>tpz<70> file extension for Topaz books and will use <20>azw<7A> 
-for non topaz books.  The files with the <20>azw<7A> format can be converted to other ebook formats using 
-Calibre.  If you want to convert Topaz books to other formats you need to use Topaz tools not skindle.
-6. The program will then create a command line and call the skindle program to process the book and 
-remove the DRM.
-7. The program will pause and allow you to see the result of the skindle process.  
-8. Press any key to close the program.
-
-version 1.1
-Ok
-
-Found a new 32 bit compiler and I think I have worked out the kinks.

-Readme.txt
-
-- 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.

-/*
-  What: KindleForPC DRM removal utility to preserve your fair use rights!
-  Why: Fair use is a well established doctrine, and I am no fan of vendor
-       lockin.
-  How: This utility implements the PID extraction, DRM key generation and
-       decryption algorithms employed by the KindleForPC application. This
-       is a stand alone app that does not require you to determine a PID on
-       your own, and it does not need to run KindleForPC in order to extract
-       any data from memory.
-  
-  Shoutz: The DarkReverser - thanks for mobidedrm!  The last part of this
-       is just a C port of mobidedrm.
-       labba and I<3cabbages for motivating me to do this the right way.
-       You guys shouldn't need to spend all your time responding to all the
-       changes Amazon is going to force you to make in unswindle each time
-       the release a new version.
-       CMBDTC - nice work on the topaz break!
-       Lawrence Lessig - You are my hero. 'Nuff said.
-       Cory Doctorow - A voice of reason in a sea of insanity
-   Thumbs down: Disney, MPAA, RIAA - you guys suck.  Making billions off 
-       of the exploitation of works out of copyright while vigourously
-       pushing copyright extension to prevent others from doing the same
-       is the height of hypocrasy.
-       Congress - you guys suck too.  Why you arrogant pricks think you
-       are smarter than the founding fathers is beyond me.
- */
-
-Rationale:
-Need a tool to enable fair use of purchased ebook content.
-Need a tool that is not dependent on any particular version of
-KindleForPC and that does not need to run KindleForPC in order to
-extract a PID. The tool documents the structure of the kindle.info
-file and the data and algorthims that are used to derive per book
-PID values.
-
-Installing:
-A compiled binary is included.  Though it was built using cygwin, it
-should not require a cygwin installation in order to run it.  To build
-from source, you will need cygwin with gcc and make.  
-This has not been tested with Visual Studio, though you may be able to
-pile all the files into a project and add the Crypt32.lib, Advapi32 and
-zlib1 dependencies to build it.
-
-usage: ./skindle [-d] [-v] -i <ebook file> -o <output file> [-k kindle.info file] [-p pid]
-    -d optional, for topaz files only, produce a decompressed output file
-    -i required name of the input mobi or topaz file
-    -o required name of the output file to generate
-    -k optional kindle.info path
-    -v dump the contents of kindle.info
-    -p additional PID values to attempt (can specifiy multiple times)
-
-You only need to specify a kindle.info path if skindle can't find
-your kindle.info file automatically

-  The code is derived from the text of the RFC, including the test suite

-  The original and principal author of md5.h is L. Peter Deutsch
-  <ghost@aladdin.com>.  Other authors are noted in the change history
-  that follows (in reverse chronological order):
-
-  2002-04-13 lpd Removed support for non-ANSI compilers; removed
-	references to Ghostscript; clarified derivation from RFC 1321;
-	now handles byte order either statically or dynamically.
-  1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
-  1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
-	added conditionalization for C++ compilation from Martin
-	Purschke <purschke@bnl.gov>.
-  1999-05-03 lpd Original version.

-  What: KindleForPC DRM removal utility to preserve your fair use rights!
-  Why: Fair use is a well established doctrine, and I am no fan of vendor
-       lockin.
-  How: This utility implements the PID extraction, DRM key generation and
-       decryption algorithms employed by the KindleForPC application. This
-       is a stand alone app that does not require you to determine a PID on
-       your own, and it does not need to run KindleForPC in order to extract
-       any data from memory.
-  
-  Shoutz: The DarkReverser - thanks for mobidedrm!  The last part of this
-       is just a C port of mobidedrm.
-       labba and I<3cabbages for motivating me to do this the right way.
-       You guys shouldn't need to spend all your time responding to all the
-       changes Amazon is going to force you to make in unswindle each time
-       the release a new version.
-       Lawrence Lessig - You are my hero. 'Nuff said.
-   Thumbs down: Disney, MPAA, RIAA - you guys suck.  Making billions off 
-       of the exploitation of works out of copyright while vigourously
-       pushing copyright extension to prevent others from doing the same
-       is the height of hypocrasy.
-       Congress - you guys suck too.  Why you arrogant pricks think you
-       are smarter than the founding fathers is beyond me.

-# 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.

-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.

-#
-# It can run standalone to convert files, or it can be installed as a

-# 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.
