# 2 - Add OS X support by using OpenSSL when available (taken/modified from ineptepub v5)
# 2.1 - Allow Windows versions of libcrypto to be found
# 2.2 - On Windows try PyCrypto first and then OpenSSL next
# 2.3 - Modify interface to allow use of import
# 2.4 - Improvements to UI and now works in plugins
# 2.5 - Additional improvement for unicode and plugin support
# 2.6 - moved unicode_argv call inside main for Windows DeDRM compatibility
# 2.7 - Work if TkInter is missing
# 2.8 - Fix bug in stand-alone use (import tkFileDialog)
# 3.0 - Added Python 3 compatibility for calibre 5.0
# 3.1 - Remove OpenSSL support, only PyCryptodome is supported now
