# Windows users: Before running this program, you must first install Python.
|
|
# We recommend ActiveState Python 2.7.X for Windows (x86) from
|
|
# http://www.activestate.com/activepython/downloads.
|
|
# You must also install PyCrypto from
|
|
# http://www.voidspace.org.uk/python/modules.shtml#pycrypto
|
|
# (make certain to install the version for Python 2.7).
|
|
# Then save this script file as ignoblekeygen.pyw and double-click on it to run it.
|
|
#
|
|
# Mac OS X users: Save this script file as ignoblekeygen.pyw. You can run this
|
|
# program from the command line (python ignoblekeygen.pyw) or by double-clicking
|
|
# it when it has been associated with PythonLauncher.
|
|
|
|
# Revision history:
|
|
# 1 - Initial release
|
|
# 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
