example of node.js ssl server

node-ssl-server.js

// You can generate the privatekey.pem and certificate.pem files using the following commands:
//
// openssl genrsa -out privatekey.pem 1024 
// openssl req -new -key privatekey.pem -out certrequest.csr 
// openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem

const crypto = require('crypto'),
      fs = require("fs"),
      http = require("http");

var privateKey = fs.readFileSync('privatekey.pem');
var certificate = fs.readFileSync('certificate.pem');

var credentials = crypto.createCredentials({key: privateKey.toString(), cert: certificate.toString()});

var handler = function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
};

var server = http.createServer();
server.setSecure(credentials);
server.addListener("request", handler);
server.listen(8000);
