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);

const EVP_MD *
EVP_sha3_256(void);

const EVP_MD *
EVP_sha3_384(void);

const EVP_MD *
EVP_sha3_512(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.
