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:

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, as well as to fix some minor bugs/
There are 2 scripts:
The first is ignoblekeygen_vX.X.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_vX.X.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.
