Monoalphabetic Substitution Cipher

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.

DOM translated Asynchronous XHTML lets you communicate with your server via AJAX, and recieve plain XHTML + scripts that are then translated to your DOM for easy insertion/substitution. What does this mean?: AJAX with no innerHTML and no cryptic XML!

Ganza is a cryptanalysis tool for classical ciphers (mono and polyalphabetic) that lets the user define almost completely arbitrary cipher and plain alphabets, allowing for the proper cryptanalysis of cryptograms obtained from non-English texts.
