Additional important notes:

This program is rather dirty because of the hurry in which I had to write it. I might need to beautify it eventually. See the improvements section in wiki for more details.

Warning:

Do NOT to use any non standard cryptographic algorithm for anything serious. 99% of the algorithms out there are unsafe to use.
