The cryptographic function known as Keccak (pronounced “ketchak”) was created by Guido Bertoni, Joan Daemen, Michal Peeters, and Gilles Van Assche. Keccak is primarily recognized as a hash function that offers higher degrees of security in comparison to more traditional hash algorithms like SHA-1 and SHA-2, even if they may be used for other things.
The US National Institute of Standards and Technology published a collection of cryptographic hash algorithms known as SHA, or Secure Hash Algorithm (NIST). The US National Security Agency (NSA), which created both SHA-1 and SHA-2, shared similar design philosophy.
Keccak’s operating system is very different from SHA-2’s, despite the fact that both programs allow the same output size (hash lengths).
