gnutls_fingerprint - calculate the fingerprint of the given data
int gnutls_fingerprint(gnutls_digest_algorithm_t algo, const
gnutls_datum_t * data, void * result, size_t * result_size);
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.
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.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code
