Message Digest hash
Returns the MD5 (Message-Digest algorithm 5) of string
MD5 is a widely used, Internet standard (RFC 1321), hash function that computes a 128-bit hash, commonly used to check the integrity of files. It is not recommended for serious cryptographic protection, for which strong hashes should be used.
