NAME¶

gnutls_hmac_fast - API function

SYNOPSIS¶

#include <gnutls/crypto.h>

int gnutls_hmac_fast(gnutls_mac_algorithm_t algorithm, const void * key, size_t keylen, const void * ptext, size_t ptext_len, void * digest);

ARGUMENTS¶

gnutls_mac_algorithm_t algorithm

the hash algorithm to use

const void * key

the key to use

size_t keylen

the length of the key

const void * ptext

the data to hash

size_t ptext_len

the length of data to hash

void * digest

is the output value of the hash

DESCRIPTION¶

This convenience function will hash the given data and return output on a single call. Note, this call will not work for MAC algorithms that require nonce (like UMAC or GMAC).
