@deftypefun {int} {gnutls_openpgp_crt_get_fingerprint} (gnutls_openpgp_crt_t @var{key}, void * @var{fpr}, size_t * @var{fprlen})
@var{key}: the raw data that contains the OpenPGP public key.

@var{fpr}: the buffer to save the fingerprint, must hold at least 20 bytes.

@var{fprlen}: the integer to save the length of the fingerprint.

Get key fingerprint.  Depending on the algorithm, the fingerprint
can be 16 or 20 bytes.

@strong{Returns:} On success, 0 is returned.  Otherwise, an error code.
