@deftypefun {int} {gnutls_openpgp_privkey_get_fingerprint} (gnutls_openpgp_privkey_t @var{key}, void * @var{fpr}, size_t * @var{fprlen})
@var{key}: the raw data that contains the OpenPGP secret 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 the fingerprint of the OpenPGP key. Depends on the
algorithm, the fingerprint can be 16 or 20 bytes.

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

@strong{Since:} 2.4.0
