(JavaScript) Create CAdES Signature (.p7s) Compliant with ICP-Brazil Digital Signature Standard PA AD RB v2.2

See more CAdES Examples

For more information, see https://validar.iti.gov.br/

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

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

// Note: This example creates a 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
