sha3 2.1.0

A high-performance native binding to the SHA3 (FIPS 202) cryptographic hashing algorithms, based on the XKCP - eXtended Keccak Code Package. This gem provides support for the standard SHA-3 fixed-length functions (224, 256, 384, and 512 bits), as well as the SHAKE128/SHAKE256 extendable-output functions (XOFs) and KMAC (Keccak Message Authentication Code) as specified in NIST SP 800-185.'
