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

Overview

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).
