(JavaScript) Use Installed Cert on Windows for TLS Client Authentication

Demonstrates how to use a certificate that has already been installed on a Windows PC for TLS client authentication.

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;

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

var http = new CkHttp();

// On Windows, a pre-installed certificate can be loaded in a number of different ways.
// This example loads by the common name:
var cert = new CkCert();
success = cert.LoadByCommonName("My ECA Medium Assurance Identity Certificate");
if (success !== true) {
    console.log(cert.LastErrorText);
    return;
}

// Make sure this certificate has a private key available.  
// It should be a private key such that when the certificate was installed, it was marked as "exportable"
// so that authorized programs are able to access the private key.
if (cert.HasPrivateKey() !== true) {
    console.log("A private key is needed for TLS client authentication.");
    console.log("This certificate has no private key.");
    return;
}

// Set the certificate to be used for mutual TLS authentication
// (i.e. sets the client-side certificate for two-way TLS authentication)
success = http.SetSslClientCert(cert);
if (success !== true) {
    console.log(http.LastErrorText);
    return;
}

// At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS
// connection will automatically use it if the server demands a client-side cert.
