gnutls_fingerprint(3) gnutls gnutls_fingerprint(3)
gnutls_fingerprint - API function
#include <gnutls/gnutls.h>
int gnutls_fingerprint(gnutls_digest_algorithm_t algo, const
gnutls_datum_t * data, void * result, size_t * result_size);
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.
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.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error
code is returned.
