gnutls_crypto_register_mac(3)

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 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.

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
