NAME

gnutls_crypto_register_mac − API function

SYNOPSIS

#include <gnutls/crypto.h>

int gnutls_crypto_register_mac(gnutls_mac_algorithm_t

algorithm

, int

priority

, gnutls_mac_init_func

init

, gnutls_mac_setkey_func

setkey

, gnutls_mac_setnonce_func

setnonce

, gnutls_mac_hash_func

hash

, gnutls_mac_output_func

output

, gnutls_mac_deinit_func

);

ARGUMENTS

gnutls_mac_algorithm_t algorithm is the gnutls MAC identifier

int priority is the priority of the algorithm

gnutls_mac_init_func init A function which initializes the MAC

gnutls_mac_setkey_func setkey A function which sets the key of the MAC

gnutls_mac_setnonce_func setnonce A function which sets the nonce for the mac (may be NULL

for common MAC algorithms)

gnutls_mac_hash_func hash Perform the hash operation

gnutls_mac_output_func output Provide the output of the MAC

gnutls_mac_deinit_func deinit A function which deinitializes the MAC

gnutls_mac_fast_func hash_fast Perform the MAC operation in one go

DESCRIPTION

This function will register a MAC algorithm to be used by gnutls. Any algorithm registered will override the included algorithms and by convention kernel implemented algorithms have priority of 90 and CPU−assisted of 80. The algorithm with the lowest priority will be used by gnutls.

DEPRECATED

since 3.7.0 it is no longer possible to override cipher implementation

RETURNS

GNUTLS_E_SUCCESS

on success, otherwise a negative error code.

SINCE

3.4.0
