SHA-3 is a subset of the broader cryptographic primitive family Keccak (/ ˈ k ɛ tʃ æ k / or / ˈ k ɛ tʃ ɑː k /), [8] [9] designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, building upon RadioGatún.
Cryptographic weaknesses were discovered in SHA-1, and the standard was no longer approved for most cryptographic uses after 2010. SHA-2: A family of two similar hash functions, with different block sizes, known as SHA-256 and SHA-512. They differ in the word size; SHA-256 uses 32-bit words where SHA-512 uses 64-bit words.
SHA-3 is a subset of the broader cryptographic primitive family Keccak. The Keccak algorithm is the work of Guido Bertoni, Joan Daemen, Michael Peeters, and Gilles Van Assche. Keccak is based on a sponge construction, which can also be used to build other cryptographic primitives such as a stream cipher.

[2] The competition ended on October 2, 2012, when NIST announced that Keccak would be the new SHA-3 hash algorithm. [3] The winning hash function has been published as NIST FIPS 202 the "SHA-3 Standard", to complement FIPS 180-4, the Secure Hash Standard. The NIST competition has inspired other competitions such as the Password Hashing ...
The sponge construction can also be used to build practical cryptographic primitives. For example, Keccak cryptographic sponge with a 1600-bit state has been selected by NIST as the winner in the SHA-3 competition. The strength of Keccak derives from the intricate, multi-round permutation f that its authors developed. [5]
