WC_REST_Authentication::check_oauth_timestamp_and_nonce() private WC 1.0

Verify that the timestamp and nonce provided with the request are valid. This prevents replay attacks where an attacker could attempt to re-send an intercepted request at a later time.

  • A timestamp is valid if it is within 15 minutes of now.
  • A nonce is valid if it has not been used within the last 15 minutes.
