@Necrocide: you ever tried to decrypt md5?^^

have a look at e.g. base64_encode and base64_decode (use the function list on http://php.net), maybe this one could be also interesting for you: http://php.net/manua.../ref.mcrypt.php

Decrypting? Not alone, hehe - I was just awaiting his answer before I explain that it is not that easy to decrypt md5. But if he is thinking of encrypt some text in php, he could use, eehh:

<?
$encryptthis = "You never guess this!";
$result = md5($encryptthis);
echo "Decrypted: $encryptthis - Encrypted: $result";
?>
