# ineptkey.pyw, version 4.4
# ineptkeyv44
# To run this program install Python 2.6 from http://www.python.org/download/
# and PyCrypto from http://www.voidspace.org.uk/python/modules.shtml#pycrypto
# (make sure to install the version for Python 2.6). Save this script file as
# ineptkey.pyw and double-click on it to run it. It will create a file named
# adeptkey.der in the same directory. These are your ADEPT user keys.
# Revision history:
# 1 - Initial release, for Adobe Digital Editions 1.7
# 2 - Better algorithm for finding pLK; improved error handling
# 3 - Rename to INEPT
# 4.1 - quick beta fix for ADE 1.7.2 (anon)
# 4.2 - added old 1.7.1 processing
# 4.3 - better key search
# 4.4 - Make it working on 64-bit Python
