(JavaScript) Socket TLS Mutual Authentication (Client-Side Certificate)

This example demonstrates how to provide a client-side certificate, also known as "two-way authentication" or "mutual authentication" for servers that require a client certificate.

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

var sock = new CkSocket();

// Set the certificate to be used for mutual TLS authentication
// (i.e. sets the client-side certificate for two-way TLS authentication)
success = sock.SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx","pfxPassword");
if (success !== true) {
    console.log(sock.LastErrorText);
    return;
}

// Note: The certificate used for the client-side of TLS mutual authentication
// must have the associated private key available. (.pfx/.p12 files typically store both
// the certificate and associated private key.)

// Establish the connection using the socket object (with client certificate authentication).
var bTls = true;
var port = 443;
var maxWaitMs = 5000;
success = sock.Connect("www.example.com",port,bTls,maxWaitMs);
if (success !== true) {
    console.log("Connect Failure Error Code: " + sock.ConnectFailReason);
    console.log(sock.LastErrorText);
    return;
}

// At this point, the Socket object is connected and authenticated using the client-side cert
