(JavaScript) SSL Client Certificate

Demonstrates how to connect to an SSL server using a client-side certificate, send a simple message, receive a simple response, and disconnect.

Note: This example requires Chilkat v10.1.2 or greater.

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 socket = new CkSocket();

// Create an instance of a certificate store object, load a PFX file,
// locate the certificate we need, and use it for signing.
// (a PFX file may contain more than one certificate.)
var certStore = new CkCertStore();
// The 1st argument is the filename, the 2nd arg is the 
// PFX file's password:
success = certStore.LoadPfxFile("chilkat_secret.pfx","secret");
if (success !== true) {
    console.log(certStore.LastErrorText);
    return;
}

// Find the certificate by the subject common name:
var jsonCN = new CkJsonObject();
jsonCN.UpdateString("CN","cert common name");

var cert = new CkCert();
success = certStore.FindCert(jsonCN,cert);
if (success == false) {
    console.log(certStore.LastErrorText);
    return;
}

success = socket.SetSslClientCert(cert);

var ssl = true;
var maxWaitMillisec = 20000;

// The SSL server hostname may be an IP address, a domain name,
// or "localhost".  You'll need to change this:
var sslServerHost;
sslServerHost = "123.123.88.88";
var sslServerPort = 8123;

// Connect to the SSL server:
success = socket.Connect(sslServerHost,sslServerPort,ssl,maxWaitMillisec);
if (success !== true) {
    console.log(socket.LastErrorText);
    return;
}

// Set maximum timeouts for reading an writing (in millisec)
socket.MaxReadIdleMs = 20000;
socket.MaxSendIdleMs = 20000;

// Send a "Hello Server! -EOM-" message:
success = socket.SendString("Hello Server! -EOM-");
if (success !== true) {
    console.log(socket.LastErrorText);
    return;
}

// The server (in this example) is going to send a "Hello Client! -EOM-" 
// message.  Read it:
var receivedMsg = socket.ReceiveUntilMatch("-EOM-");
if (socket.LastMethodSuccess !== true) {
    console.log(socket.LastErrorText);
    return;
}

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
success = socket.Close(20000);

console.log(receivedMsg);
