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.
EVP_sha3_512()
The SHA-3 SHA-3-224, SHA-3-256, SHA-3-384, and SHA-3-512 algorithms respectively. They produce 224, 256, 384 and 512 bits of output from a given input.
EVP_shake256()
The SHAKE-128 and SHAKE-256 Extendable Output Functions (XOF) that can generate a variable hash length.
Specifically, EVP_shake128 provides an overall security of 128 bits, while EVP_shake256 provides that of 256 bits.
These functions return a EVP_MD structure that contains the implementation of the symmetric cipher. See EVP_MD_meth_new(3) for details of the EVP_MD structure.
