Create CAdES Signature (.p7s) Compliant with ICP-Brazil Digital Signature Standard

See more CAdES Examples

Demonstrates how to create a CMS signature w/ policy ID that is compliant with the ICP-Brazil Digital Signature Standard. Swift

func chilkatTest() {
    var success: Bool = false

    // 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
    // ------------------------------------------------------------------------------------------------------
