# Copyright © 2009-2022 i♥cabbages, Apprentice Harper et al.
# Released under the terms of the GNU General Public Licence, version 3
# <http://www.gnu.org/licenses/>
# 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 - Series of changes by joblack (and others?) --
# 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
# 5 - Clean up and improve 4.x changes;
# Clean up and merge OS X support by unknown
# 5.1 - add support for using OpenSSL on Windows in place of PyCrypto
# 5.2 - added support for output of key to a particular file
# 5.3 - On Windows try PyCrypto first, OpenSSL next
# 5.4 - Modify interface to allow use of import
# 5.5 - Fix for potential problem with PyCrypto
# 5.6 - Revised to allow use in Plugins to eliminate need for duplicate code
# 5.7 - Unicode support added, renamed adobekey from ineptkey
# 5.8 - Added getkey interface for Windows DeDRM application
# 5.9 - moved unicode_argv call inside main for Windows DeDRM compatibility
# 6.0 - Work if TkInter is missing
# 7.0 - Python 3 for calibre 5
# 7.1 - Fix "failed to decrypt user key key" error (read username from registry)
# 7.2 - Fix decryption error on Python2 if there's unicode in the username
# 7.3 - Fix OpenSSL in Wine
# 7.4 - Remove OpenSSL support to only support PyCryptodome
