What is SHA?

The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard. SHA-256 and SHA-512 are novel hash functions computed with 32-bit and 64-bit words, respectively.
