Create .p7s Compliant with ICP-Brazil Digital Signature Standard

See more CAdES Examples

Demonstrates how to create a .p7s signature that contains a data file, which in this case is a PDF. The .p7s will be compliant with the ICP-Brazil Digital Signature Standard.

Important: This example requires Chilkat v9.5.0.92 or later.
