gnutls_crypto_register_mac − API function


, int int gnutls_crypto_register_mac(gnutls_mac_algorithm_t

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.

GNUTLS_E_SUCCESS on success, otherwise a negative error
