@deftypefun {int} {gnutls_x509_privkey_import} (gnutls_x509_privkey_t @var{key}, const gnutls_datum_t * @var{data}, gnutls_x509_crt_fmt_t @var{format})
@var{key}: The data to store the parsed key

@var{data}: The DER or PEM encoded certificate.

@var{format}: One of DER or PEM

This function will convert the given DER or PEM encoded key to the
native @code{gnutls_x509_privkey_t}  format. The output will be stored in
 @code{key} .

If the key is PEM encoded it should have a header that contains "PRIVATE
KEY". Note that this function falls back to PKCS @code{8}  decoding without
password, if the default format fails to import.

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