It should get. My 5.

Don't forget MD5 is considered as "broken". Using it for security purposes is a bad idea. See http://en.wikipedia.org/wiki/MD5[^] for more information.

Recommended replacement would be a cryptographic hash function from SHA family, see http://en.wikipedia.org/wiki/SHA-1[^]. On that page you will find a pseudo-code; implementing of the code would be easy enough.
