Secure online hiscore & PHP cypher functions ( AES MD5 SHA ... )

Hi,

First, TGB is great.

I know it's possible to save hiscore entry. I found a good example.
( ex: http://hiscoreserver.php ? name = ABCD123 & hiscore = 10000 & level = 5 )

But because of cheating, I have to encrypt datas that I sent to my PHP server.
I used to code PHP script with functions MD5 and/or SHA256.

Does TGB support some cypher functions ?
( ex: MD5 SHA AES ... )

Thx for advance.
