    Remarks

    This feature is for use with the Professional Edition license only. An evaluation message is rendered when used with the Standard Edition license.

    Note: This feature can not be used if a report is exported into a password-protected PDF document.

    In the code example above, replace the path and filename and password of the Certificate with your certificate information, and replace the time stamping authority (TSA) URL with that of your TSA.

    Note: You must purchase a volume-based registration at an actual TSA for your applications.
