MD5 is a cryptographic one-way hashing algorithm first described in RFC 1321 back in 1992.
MD5 is no longer recommended for use, following a presentation at the 2004 Crypto Conference that revealed hash collision problems with the algorithm. One replacement perhaps is SHA256.
This MD5 sum is infamous:

What is it? An empty file.
Salted MD5 passwords broken
With off the shelf hardware.. see {http://securityledger.com/new-25-gpu-monster-devours-passwords-in-seconds/ here] it's probably wise to use another cipher, perhaps bcrypt based on many rounds of blowfish.
