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 deinit, gnutls_mac_fast_func hash_fast);

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.

Returns

GNUTLS_E_SUCCESS on success, otherwise a negative error code.
