Class

OAuthSignatureMethod_HMAC

A generic signature method implementation that leverages hash_hmac() for increased flexibility.

Code

public function build_signature($request, $consumer, $token) {
  $base_string = $request
    ->get_signature_base_string();
  $request->base_string = $base_string;
  $key_parts = array(
    $consumer->secret,
    $token ? $token->secret : "",
  );
  $key_parts = OAuthUtil::urlencode_rfc3986($key_parts);
  $key = implode('&', $key_parts);
  return base64_encode(hash_hmac($this->algo, $base_string, $key, TRUE));
}
