SYNOPSIS

#include <gnutls/gnutls.h>

int gnutls_fingerprint(gnutls_digest_algorithm_t algo, const gnutls_datum_t * data, void * result, size_t * result_size);

ARGUMENTS

gnutls_digest_algorithm_t algo is a digest algorithm
const gnutls_datum_t * data is the data
void * result is the place where the result will be copied (may be null).
size_t * result_size should hold the size of the result. The actual size of the returned result will also be copied there.

DESCRIPTION

This function will calculate a fingerprint (actually a hash), of the given data. The result is not printable data. You should convert it to hex, or to something else printable.

This is the usual way to calculate a fingerprint of an X.509 DER encoded certificate. Note however that the fingerprint of an OpenPGP certificate is not just a hash and cannot be calculated with this function.

RETURNS

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
