gnutls_crypto_register_mac - API function
#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);
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
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.
since 3.7.0 it is no longer possible to override cipher
implementation
GNUTLS_E_SUCCESS on success, otherwise a negative error code.
3.4.0
