[quote="madster":1deybvsy]MD5 is NOT an encryption algorithm. It's a hash.[/quote:1deybvsy]
Very true..I was going to post the same.
You actually can encrypt with SHA-1 or MD5 if you use an HMAC...but it is not straightforward:http://en.wikipedia.org/wiki/HMAC...although
I wouldn't recommend using MD5 due to hash collisions.
So in summary.. use S or Python.
