NAME
gnutls_fingerprint - This function calculates the fingerprint of the
given data
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 is
not just a hash and cannot be calculated with this function.
Returns a negative value in case of an error.
