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 re-
quire nonce (like UMAC or GMAC).
