SHA-3 (Secure Hash Algorithm 3) is a family of cryptographic hash functions standardized in NIST FIPS 202, first published in 2015. It is based on the Keccak algorithm.

(), (), (), and () implement the SHA3-224, SHA3-256, SHA3-384, and SHA3-512 algorithms and produce 224, 256, 384 and 512 bits of output from a given input, respectively.

These functions return pointers to static EVP_MD objects implementing the hash functions.
