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).

RETURNS

Zero or a negative error code on error.
