A government standard hash function developed by the National Institute of Standards and Technology (NIST) and specified in an official government publication. SHA-1 creates a 160-bit hash value output. Members of the SHA-2 family create a range of hash value outputs: 224, 256, 384 or 512. SHA-3 was still in development at the time of this writing, but the Keccak algorithm has been selected for that emerging standard.

The version of the MD algorithm released in 1991. MD5 processes 512-bit blocks of the message, using four distinct rounds of computation to produce a digest of the same length as the MD2 and MD4 algorithms (128 bits). Generally has been replaced by SHA-1 or other, more modern hashing algorithms.
