gnutls_crypto_register_mac(3) gnutls 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.
