Adobe Adept PDF, .pdf
This directory includes modified versions of the I♥CABBAGES Adobe Adept inept scripts for pdfs. These scripts have been modified to work with OpenSSL on Windows as well as Linux and Mac OS X. If a Windows User has OpenSSL installed, these scripts will make use of it in place of PyCrypto.
The wonderful I♥CABBAGES has produced scripts that will remove the DRM from ePubs and PDFs encryped with Adobes DRM. These scripts require installation of the PyCrypto python package *or* the OpenSSL library on Windows. For Mac OS X and Linux boxes, these scripts use the already installed OpenSSL libcrypto so there is no additional requirements for these platforms.
For more info, see the author's blog:
http://i-u2665-cabbages.blogspot.com/2009_02_01_archive.html
There are two scripts:
The first is called ineptkey_vX.X.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.

# This is a simple tool to identify all Amazon Topaz ebooks in a specific directory.
# There always seems to be confusion since Topaz books downloaded to K4PC/Mac can have
# almost any extension (.azw, .azw1, .prc, tpz). While the .azw1 and .tpz extensions
# are fairly easy to indentify, the others are not (without opening the files in an editor).
# To run the tool with the GUI frontend, just double-click on the 'FindTopazFiles.pyw' file
# and select the folder where all of the ebooks in question are located. Then click 'Search'.
# The program will list the file names of the ebooks that are indentified as being Topaz.
# You can then isolate those books and use the Topaz tools to decrypt and convert them.
# You can also run the script from a command line... supplying the folder to search
# as a parameter: python FindTopazEbooks.pyw "C:\My Folder" (change appropriately for
# your particular O.S.)
# ** NOTE: This program does NOT decrypt or modify Topaz files in any way. It simply identifies them.
# PLEASE DO NOT PIRATE EBOOKS!
# We want all authors and publishers, and eBook stores to live
# long and prosperous lives but at the same time we just want to
# be able to read OUR books on whatever device we want and to keep
# readable for a long, long time
# This borrows very heavily from works by CMBDTC, IHeartCabbages, skindle,
# unswindle, DarkReverser, ApprenticeAlf, DiapDealer, some_updates
# and many many others
# Revision history:
# 1 - Initial release.

Welcome to the tools!
The set includes tools to remove DRM from eReader PDB books, Barnes and Noble ePubs, Adobe ePubs, Adobe PDFs, and Kindle/Mobi ebooks (including Topaz).
This ReadMe_First.txt is meant to give users a quick overview of what is available and how to get started.
Calibre Users (Mac OS X, Linux, Windows)
-------------
If you are a calibre user, the quickest and easiest way to remove DRM form your ebooks is to open the Calibre_Plugins folder and install each of the plugins following the instructions and configuration directions provided in each plugins README file.
Once installed and configured, you can simply import a DRM book into Calibre and end up with the DeDRM version in the Calibre database.
These plugins work for Windows, Mac OS X, and Linux
Mac OS X Users (Mac OS X 10.5 and 10.6)
--------------
Drag the DeDRM X.X.app droplet to your Desktop. Double-click on it once and it will guide you through collecting the data it needs to remove the DRM.
To use it simply drag a book onto the droplet, and a DeDRM version will appear. This tools supports dragging and dropping of folders of ebooks as well.
Not a Calibre or a Mac OS X DeDRM User?
----------------------------------------
There are a number of 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.
On Mac OS X (10.5 and 10.6) and Linux (recent versions), your systems already have the proper Python and OpenSSL installed. So nothing need be done, you can already run these tools by double-clicking on the .pyw python scripts.
Users of Mac OS X 10.3 and 10.4, need to download and install the "32-bit Mac Installer disk Image (2.7.X) for OS X 10.3 and later from http://www.python.org/download/releases/2.7.1/
On Windows, you need to install a 32 bit version of Python (even on Windows 64) plus a matching 32 bit version of PyCrypto *OR* OpenSSL. See the end of this document for details.
The scripts are organized by type of ebook you need to remove the DRM from. Choose from among:
"Adobe_ePub_Tools"
"Adobe_PDF_Tools"
"Barnes_and_Noble_ePub_Tools"
"eReader_PDB_Tools"
"KindleBooks_Tools"
by simply opening that folder.
In the "KindleBooks_Tools" folder the primary tool is in the "KindleBooks" folder.
If you are a Windows user, or a Linux platform using Wine, or Mac OS X or have trouble running the KindleBooks tools, there are two other tools provided. These are called "Kindle_4_Mac_Unswindle" and "Kindle_4_PC_Unswindle".
Look for a README inside of the relevant folder to get you started.
Additional Tools
----------------------
Some additional tools are also provided in the "Mobi_Additional_Tools" folder. There are tools for working with "Kindle for iPhone/iPod_Touch/iPad", finding Topaz ebooks, unpacking Mobi ebooks (without DRM) to get to the Mobi markup language inside, and etc.
There is also an "ePub_Fixer" folder that can be used to fix broken DRM epubs that sometimes provided by Adobe and Barnes and Noble that actually violate the zip standard.
Check out their readmes for more info.
Windows and Python Tools
------------------------
We strongly recommend ActiveState's Active Python 2.6 or 2.7 Community Edition for Windows (x86) 32 bits. This can be downloaded for free from:
http://www.activestate.com/activepython/downloads
In addition, Windows Users need one of PyCrypto OR OpenSSL.
For OpenSSL:
Win32 OpenSSL v0.9.8o (8Mb)
http://www.slproweb.com/download/Win32OpenSSL-0_9_8o.exe
(if you get an error message about missing Visual C++
redistributables... cancel the install and install the
below support program from Microsoft, THEN install OpenSSL)
Visual C++ 2008 Redistributables (1.7Mb)
http://www.microsoft.com/downloads/details.aspx?familyid=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF
For PyCrypto:
There are many places to get PyCrypto installers for Windows. One such place is:
http://www.voidspace.org.uk/python/modules.shtml
Please get the latest PyCrypto meant for Windows 32 bit that matches the version of Python you installed (2.7, or 2.6)
Once Windows users have installed Python 2.X for 32 bits, and the matching OpenSSL OR PyCrypto pieces, they too are ready to run the scripts.

ePub_Fixer
ePubs are specially crafted zip archives. Unfortunately, many of te DRM encoded Adobe Adept and Barnes & Noble ePubs are not "proper" zip archives in that the names of some files in the zip central directory do NOT match the local name given in archive itself. This type of zip archive is technically incorrect/corrupted and can not be read by many other programs.
