Creating Self-Signed Certificates

In addition, the provided answer describes the steps involved in generating a self-signed certificate.

Creating HTTPS Servers with Express

Here's a commented code snippet adapted from the Node.js HTTPS documentation:

var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');

// Define SSL options using the provided key and certificate.
var options = {
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.cert')
};

// Create an Express application (a callback function).
var app = express();

// Create an HTTP service.
http.createServer(app).listen(80);
// Create an HTTPS service identical to the HTTP service.
https.createServer(options, app).listen(443);

This code creates both HTTP and HTTPS services using the provided SSL key and certificate, allowing secure communication over HTTPS.
