Configure a Socket for Server-Side TLS

Demonstrates Socket.InitSslServer, which configures the object for server-side TLS using a server certificate that has access to its private key, then listens for and accepts a TLS connection.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Background. A TLS listener presents the configured server certificate during the handshake. When client certificates are required, acceptable CA distinguished names are added before InitSslServer.

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.

JavaScript

var success = false;

var socket = new CkSocket();

//  The file path is relative to the application's current working directory.  An absolute path
//  may also be used.  Supply the path appropriate to your own environment.
//  The PFX password should come from a secure source rather than being hard-coded.
var pfxPassword = "myPfxPassword";
var cert = new CkCert();
success = cert.LoadPfxFile("qa_data/server.pfx",pfxPassword);
if (success == false) {
    console.log(cert.LastErrorText);
    return;
}

//  Configure this object for server-side TLS using the certificate.  The certificate must have
//  access to its corresponding private key.
success = socket.InitSslServer(cert);
if (success == false) {
    console.log(socket.LastErrorText);
    return;
}

//  Listen for connections.  Accepted connections will use TLS.
success = socket.BindAndListen(5000,25);
if (success == false) {
    console.log(socket.LastErrorText);
    return;
}

var connectedSock = new CkSocket();
success = socket.AcceptNext(20000,connectedSock);
if (success == false) {
    console.log(socket.LastErrorText);

console.log("Accepted a TLS client connection.");
