TLS client & server in NodeJS

1. Overview

This is an example of using module tls in NodeJS to create a client securely connecting to a TLS server.

It is a modified version from documentation about TLS, in which:

  • The server is a simple echo one. Clients connect to it, get the same thing back if they send anything to the server.
  • The server is a TLS-based server.
  • Clients somehow get the server's public key and use it to work securely with the server

2. Preparation
