# ineptkey.pyw, version 4

# 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.  This is your ADEPT user key.

# 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 - quick beta fix for ADE 1.7.2 (doesn't work with ADE 1.7.1 anymore) (anon)
