Set a TLS Client Certificate from a PEM

Demonstrates Socket.SetSslClientCertPem, which loads and configures a TLS client certificate and private key from PEM data or a PEM file.

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. Supply the PEM password when the private key is encrypted, and configure the client certificate before connecting. Use client certificates only for mutual TLS.

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 PEM password should come from a secure source rather than being hard-coded.
var pemPassword = "myPemPassword";

//  Load and configure the TLS client certificate and private key from a PEM file.  Configure the
//  client certificate before connecting.
success = socket.SetSslClientCertPem("qa_data/client.pem",pemPassword);
if (success == false) {
    console.log(socket.LastErrorText);
    return;

console.log("Connected with mutual TLS.");
