String hash to int

WebHash Functions MD5 Hash functions map binary strings of an arbitrary length to small binary strings of a fixed length. The MD5 algorithm is a widely used hash function producing a 128-bit hash value (16 Bytes, 32 Hexdecimal characters). The ComputeHash method of the System.Security.Cryptography.MD5 class returns the hash as an array of 16 bytes.
