Описание (Description)
This function will return the X.509v3 certificate authority's key
identifier. This is obtained by the X.509 Authority Key
identifier extension field (2.5.29.35). Note that this function
only returns the keyIdentifier field of the extension and
GNUTLS_E_X509_UNSUPPORTED_EXTENSION, if the extension contains
the name and serial number of the certificate. In that case
gnutls_x509_crt_get_authority_key_gn_serial() may be used.
Возвращаемое значение (Return value)
On success, GNUTLS_E_SUCCESS (0) is returned,
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not
present, otherwise a negative error value.
