gnutls_crypto_single_mac_register2(3)

Usage

#include <gnutls/gnutls.h>

int gnutls_crypto_single_mac_register2(gnutls_mac_algorithm_t algorithm, int priority, int version, gnutls_crypto_single_mac_st * s);

Arguments

`gnutls_mac_algorithm_t algorithm`	is the gnutls algorithm identifier
`int priority`	is the priority of the algorithm
`int version`	should be set to `GNUTLS_CRYPTO_API_VERSION`
`gnutls_crypto_single_mac_st * s`	is a structure holding new algorithms's data

Overview

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. The algorithm with the lowest priority will be used by gnutls.

This function should be called before gnutls_global_init().

For simplicity you can use the convenience gnutls_crypto_single_mac_register() macro.

Returns

GNUTLS_E_SUCCESS on success, otherwise an error.
