gnutls_crypto_register_digest — API function


#include <gnutls/crypto.h>

int gnutls_crypto_register_digest(gnutls_digest_algorithm_t algorithm, int priority, gnutls_digest_init_func init, gnutls_digest_hash_func hash, gnutls_digest_output_func output, gnutls_digest_deinit_func deinit, gnutls_digest_fast_func hash_fast);


gnutls_digest_algorithm_t algorithm

is the gnutls digest identifier

int priority

is the priority of the algorithm

gnutls_digest_init_func init

A function which initializes the digest

gnutls_digest_hash_func hash

Perform the hash operation

gnutls_digest_output_func output

Provide the output of the digest

gnutls_digest_deinit_func deinit

A function which deinitializes the digest

gnutls_digest_fast_func hash_fast

Perform the digest operation in one go


This function will register a digest 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 code.
