@deftypefun {int} {gnutls_x509_privkey_import_openssl} (gnutls_x509_privkey_t @var{key}, const gnutls_datum_t * @var{data}, const char * @var{password})
@var{key}: The data to store the parsed key

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

@var{password}: the password to decrypt the key (if it is encrypted).

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

The  @code{password} should be in ASCII. If the password is not provided
or wrong then @code{GNUTLS_E_DECRYPTION_FAILED}  will be returned.

If the Certificate is PEM encoded it should have a header of
"PRIVATE KEY" and the "DEK-Info" header. 

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