How to use:
$key = "PaSsWoRd";
$toencrypt = "Encrypt me!";
$crypt = new MD5Crypt;
$en $crypt->Encrypt($toencrypt,$key);
//encrypts but if i show you output, and you do the same exact words its probally going to be 

differnt.
$de = $crypt->Decrypt($en,$key);
makes the value of $toencrypt

If you need any help with this just email me @ axilant07@yahoo.com or im me on AIM @ axilant
