SHA (Secure Hash Algorithm) A set of cryptographic hash designed by United State National Security Agency in 1995. This hash function takes an input and output a cryptographic hash block. One- way hash that can produce a message to produce a condensed representation called a message digest or hash. Once the process through the hash function, any changes in a message or downloaded results in a different digest or hash. Therefore, these algorithms can be used to validate the integrity of the message.
