EVP_blake2b512, EVP_blake2s256 - BLAKE2 For EVP
const EVP_MD *EVP_blake2b512(void);
const EVP_MD *EVP_blake2s256(void);
BLAKE2 is an improved version of BLAKE, which was submitted to the NIST SHA-3
algorithm competition. The BLAKE2s and BLAKE2b algorithms are described in RFC
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.
While the BLAKE2b and BLAKE2s algorithms supports a variable length digest, this
implementation outputs a digest of a fixed length (the maximum length
supported), which is 512-bits for BLAKE2b and 256-bits for BLAKE2s.
