Cryptation algorithm in Actionscript 3

One of my customers ask me to pass some sensible data to server with MD5 algorithm.
So I don’t know what was MD5 algorithm and I start search some news about it… I love wikipedia!

MD5 (Message-Digest algorithm 5) is a cryptation algorithm made by Professor Ronald Rivest in ’90.
In this algorithm you can pass a string to a hash function and it returns a new 128 bit hash value (a new string).

Surfing on web I search how it works to create an AS3 version, but I find some free libraries in riaforge.org that implements
this algorithm and many other!
Very useful if you must pass any important data, so you can take a look at Houser’s AS3 library and Torgemane’s library (I love this one).

For italian developers I also put a little flex example in flex developers UG.

Enjoy!
