(JavaScript) Italian FatturaPA (e-Invoice) Signed XML (CADES-BES P7M) using USB SmartCard Reader

Demonstrates Italian e-Invoice (FatturaPA) signing by using a private key stored on a USB smartcard reader.

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