@deftypefun {int} {gnutls_certificate_set_openpgp_key_file} (gnutls_certificate_credentials_t      @var{res}, const char * @var{certfile}, const char * @var{keyfile}, gnutls_openpgp_crt_fmt_t @var{format})
@var{res}: the destination context to save the data.

@var{certfile}: the file that contains the public key.

@var{keyfile}: the file that contains the secret key.

@var{format}: the format of the keys

This funtion is used to load OpenPGP keys into the GnuTLS
credentials structure. The file should contain at least one valid non encrypted subkey.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
