-#
-# Changelog
-# 0.01 - Initial version
-# 0.02 - Huffdic compressed books were not properly decrypted
-# 0.03 - Wasn't checking MOBI header length
-# 0.04 - Wasn't sanity checking size of data record
-# 0.05 - It seems that the extra data flags take two bytes not four
-# 0.06 - And that low bit does mean something after all :-)
-# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
-# 0.08 - ...and also not in Mobi header version < 6
-# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
-# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
-# import filter it works when importing unencrypted files.
-# Also now handles encrypted files that don't need a specific PID.
-# 0.11 - use autoflushed stdout and proper return values
-# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
-# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
-# and extra blank lines, converted CR/LF pairs at ends of each line,
-# and other cosmetic fixes.
-# 0.14 - Working out when the extra data flags are present has been problematic
-# Versions 7 through 9 have tried to tweak the conditions, but have been
-# only partially successful. Closer examination of lots of sample
-# files reveals that a confusion has arisen because trailing data entries
-# are not encrypted, but it turns out that the multibyte entries
-# in utf8 file are encrypted. (Although neither kind gets compressed.)
-# This knowledge leads to a simplification of the test for the
-# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
-# 0.15 - Now outputs 'heartbeat', and is also quicker for long files.
-# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
-# 0.17 - added modifications to support its use as an imported python module
-# both inside calibre and also in other places (ie K4DeDRM tools)
-# 0.17a- disabled the standalone plugin feature since a plugin can not import
-# a plugin
-# 0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
-# Removed the disabled Calibre plug-in code
-# Permit use of 8-digit PIDs
-# 0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
-# 0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
-# 0.21 - Added support for multiple pids
-# 0.22 - revised structure to hold MobiBook as a class to allow an extended interface
-# 0.23 - fixed problem with older files with no EXTH section
-# 0.24 - add support for type 1 encryption and 'TEXtREAd' books as well
-# 0.25 - Fixed support for 'BOOKMOBI' type 1 encryption
-# 0.26 - Now enables Text-To-Speech flag and sets clipping limit to 100%
-# 0.27 - Correct pid metadata token generation to match that used by skindle (Thank You Bart!)
-# 0.28 - slight additional changes to metadata token generation (None -> '')
-# 0.29 - It seems that the ideas about when multibyte trailing characters were
-# included in the encryption were wrong. They are for DOC compressed
-# files, but they are not for HUFF/CDIC compress files!
-# 0.30 - Modified interface slightly to work better with new calibre plugin style
-# 0.31 - The multibyte encrytion info is true for version 7 files too.
-# 0.32 - Added support for "Print Replica" Kindle ebooks
-# 0.33 - Performance improvements for large files (concatenation)
-# 0.34 - Performance improvements in decryption (libalfcrypto)
-# 0.35 - add interface to get mobi_version
-# 0.36 - fixed problem with TEXtREAd and getBookTitle interface
-# 0.37 - Fixed double announcement for stand-alone operation

<p>This plugin is meant to decrypt Barnes & Noble ePubs that are protected with Adobe's Adept encryption. It is meant to function without having to install any dependencies... other than having calibre installed, of course. It will still work if you have Python and PyCrypto already installed, but they aren't necessary.</p>
0.2.1 - an updated/modified zipfix.py and included zipfilerugged.py
0.2.2 - added in potential fixes from 0.1.7 that had been missed.
0.2.3 - fixed possible output/unicode problem
+ 0.2.4 - ditched nearly hopeless caselessStrCmp method in favor of uStrCmp.
+ - added ability to rename existing keys.

Since “Me”‘s old method for getting PIDs from Kindle for Android is outdated and no longer works with newer versions of the app, I decided I’d take a stab at bringing it up to date. It took a little fiddling to get everything working, considering how much has changed since the last patch, but I managed to do it. The process is pretty much identical to “Me”‘s original instructions, with a few minor changes.
And here’s a screenshot of the updated menu: http://imgur.com/BbFVF (sorry for the Japanese, I was too lazy to change my phone’s language).

+keytool -genkey -v -keystore kindle.keystore -alias kindle -keyalg RSA -keysize 2048 -validity 10000
+As well as location of prc’s on android being (with sdcard):
+/mnt/sdcard/Android/data/com.amazon.kindle/files/
+"s" also reported success with using the patch on version 3.7.1.8, although I recommend using the 3.7.0.108 version just in case.

+This ReadMe_First.txt is meant to give users a quick overview of what is available and how to get started. This document is part of the Tools v5.4.1 archive.
The is archive includes tools to remove DRM from:
- Adobe Digital Editions PDFs
- Mobipocket ebooks
- eReader PDB books
+ - Scuolabooks (Windows only solution by Hex)
These tools do NOT work with Apple's iBooks FairPlay DRM (see end of this file.)
The original mobidedrm and erdr2pml scripts were by The Dark Reverser
The original topaz DRM removal script was by CMBDTC
The original topaz format conversion scripts were by some_updates, clarknova and Bart Simpson
+The Scuolabooks tool is by Hex
The calibre plugin conversions were originally by DiapDealer
The DeDRM AppleScript application was by Apprentice Alf

Definitely only for the adventurous, this folder contains information on how to modify the Kindel for Android app to b able to get a PID for use with the other Kindle tools (DeDRM apps and calibre plugin).
+B&N_Download_Helper
+-------------------
+A Javascript to enable a download button at the B&N website for ebooks that normally won't download to your PC. Another one only for the adventurous.
-Other_Tools
------------
-There are a number of other python based tools that have graphical user interfaces to make them easy to use. To use any of these tools, you need to have Python 2.5, 2.6, or 2.7 for 32 bits installed on your machine as well as a matching PyCrypto or OpenSSL for some tools.

Some additional useful tools **unrelated to DRM** are also provided in the "Additional_Tools" folder inside the "Other_Tools" folder. There are tools for working with finding Topaz ebooks, unpacking Kindle/Mobipocket ebooks (without DRM) to get to the Mobipocket markup language inside, tools to strip source archive from Kindlegen generated mobis, tools to work with Kindle for iPhone/iPad, etc, and tools to dump the contents of mobi headers to see all EXTH (metadata) and related values.

-echo deadbeef > .windows-serial
+echo deadbeef > .windows-serial
Replace "deadbeef" with whatever hex value you want but I would stay away from the default setting of "ffffffff" which does not seem to work. BTW: deadbeef is itself a valid possible hex value if you want to use it

1. download the most recent version of wine from winehq.org (1.3.29 in my case)
-For debian users:
+For debian users:
to get a recent version of wine I decited to use aptosid (2011-02, xfce)
(because I’m used to debian)
For debian users:
cd to this dir and install the packages as root:
-‘dpkg -i *.deb’
+‘dpkg -i *.deb’
you will get some error messages, which can be ignored.
again as root use
‘apt-get -f install’ to correct this errors

+1) Make sure you can read all PDF files on Scuolabook Reader.
+2) Run Scuolabook DRM Remover.
+3) Get your free books from the directory where you started the program.
+
+Note:
+It is recommended to use Scuolabook version 2.0.1 and refuse all updates
