private KeyStore newEmptyKeyStore(char[] password) throws GeneralSecurityException {
 try {
  KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
  InputStream in = null; // By convention, 'null' creates an empty key store.
  keyStore.load(in, password);
  return keyStore;
 } catch (IOException e) {
  throw new AssertionError(e);
 }
}
