SHA-3 is a family of cryptographic hash functions, a successor to SHA-2.

SHA-3 is a family of cryptographic hash functions, intended to replace and .

SHA-3 was chosen by NIST in a competition started in November 2007. The winner was declared to be the Keccak family in October 2012. The other finalists in the competition were BLAKE, Grøstl, JH and Skein .

As of October 2012, SHA-3 has not yet been formally codified. It is intended that the next version of FIPS PUB 180 will specify Keccak functions with digest sizes 224, 256, 384, 512.
