NAME
EVP_sha3_224, EVP_sha3_256, EVP_sha3_384, EVP_sha3_512 - Secure Hash
Algorithm 3 for EVP
SYNOPSIS
#include <openssl/evp.h>
const EVP_MD *
EVP_sha3_224(void);

DESCRIPTION
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_224(), EVP_sha3_256(), EVP_sha3_384(), and EVP_sha3_512()
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.
RETURN VALUES
These functions return pointers to static EVP_MD objects implementing the
hash functions.
