High-speed SHA-3 IP core provides versatile support of all variants of the SHA-3 hash function and related extendable-output function SHAKE as well as the SHA-3 derived function cSHAKE and its variants KMAC, TupleHash and ParallelHash (including their arbitrary-length output variants). SHA-3 and SHAKE are defined in the NIST (National Institute of Standards and Technology) standard FIPS PUB 202 and cSHAKE, KMAC, TupleHash and ParallelHash are specified in NIST Special Publication 800-185..
