* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* ------------------------------------------------------------------------------------------------------
* Note: This example creates a CAdES (CMS) signature (.p7s) that contains the PDF.
* It is different than signing a PDF.  To sign a PDF where the resulting PDF contains the CMS signature,
* see this example:  Sign PDF for ICP-Brasil
