(JavaScript) Create CAdES-BES .p7m using Smart Card or USB Token

Demonstrates how to create a CAdES BES invoice.xml.p7m using a certificate stored on a smart card or USB token.

Note: This example requires Chilkat v9.5.0.77 and at the time of this writing is restricted to the Windows operating system.

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.

var success = false;

// Note: Requires Chilkat v9.5.0.77 or greater.

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

var crypt = new CkCrypt2();

// Use a certificate on a smartcard or USB token.
var cert = new CkCert();
// Load the certificate on the smartcard currently in the reader (or on the USB token).
// Pass an empty string to allow Chilkat to automatically choose the CSP (Cryptographi Service Provider).
// See Load Certificate on Smartcard for information about explicitly selecting a particular CSP.
success = cert.LoadFromSmartcard("");
if (success !== true) {
    console.log(cert.LastErrorText);
    return;
}

// Provide the smartcard PIN.
// If the PIN is not explicitly provided here, the Windows OS should
// display a dialog for the PIN.
cert.SmartCardPin = "000000";

// Provide the certificate for signing.
success = crypt.SetSigningCert(cert);
if (success !== true) {
    console.log(crypt.LastErrorText);
    return;
}

// Indicate that SHA-256 should be used.
crypt.HashAlgorithm = "sha256";

// Specify the signed attributes to be included.
// (This is what makes it CAdES-BES compliant.)
var jsonSignedAttrs = new CkJsonObject();
jsonSignedAttrs.UpdateInt("contentType",1);
jsonSignedAttrs.UpdateInt("signingTime",1);
