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. Rust

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

// Use your smart card user PIN for signing.
cert.set_smart_card_pin("0000");

    println!("{}", cert.last_error_text());
    return;

    return;
}

// The CadesEnabled property applies to all methods that create PKCS7 signatures. 
// To create a CAdES-BES signature, set this property equal to true.
