# libressl-EVP\_sha3\_224(3)

Secure Hash Algorithm 3 for EVP

## NAME

**EVP\_sha3\_224**, **EVP\_sha3\_256**, **EVP\_sha3\_384**, **EVP\_sha3\_512** – Secure Hash Algorithm 3 for EVP

## SYNOPSIS

Crypto Library (libcrypto, -lcrypto)

**#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.
