(Node.js) Load Certificate from Smartcard in Reader (or from USB Token)

Demonstrates how to load the certificate that is on the smartcard currently inserted into the smartcard reader. (Also can load the smartcard on a USB token.)

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOSX, and ARM

var os = require('os');
if (os.platform() == 'win32') {  
    if (os.arch() == 'ia32') {
        var chilkat = require('@chilkat/ck-node21-win-ia32');
    } else {
        var chilkat = require('@chilkat/ck-node21-win64'); 
    }
} else if (os.platform() == 'linux') {
    if (os.arch() == 'arm') {

    }

function chilkatExample() {

    var cert = new chilkat.Cert();

    // If you know the smart card PIN, set it prior to loading from the smartcard/USB token.
    cert.SmartCardPin = "12345678";

    // Pass an empty string to allow Chilkat to discover the smart card or USB token automatically.
    var success = cert.LoadFromSmartcard("");
    if (success == false) {
        console.log(cert.LastErrorText);
        return;
