Socket TLS Mutual Authentication (Client-Side Certificate)

See more Socket/SSL/TLS Examples

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. Node.js

function chilkatExample() {

    var success = false;

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

    var sock = new chilkat.Socket();

    // 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

    // ...
    // ..
