Ejemplo 1: Nombre de archivo: index.js 

// Node.js program to demonstrate the
// tlsSocket.disableRenegotiation() method
var tls = require('tls'),
    fs = require('fs'),
 
// Port and host address for server   
PORT = 1337,
HOST = '127.0.0.1',
value =null;
  
// Private key and public certificate for access
var options = {
  key: fs.readFileSync('private-key.pem'),
  cert: fs.readFileSync('public-cert.pem'),
  rejectUnauthorized: false
};
 
// Creating and initializing server
var server = tls.createServer(options, function(socket) {
 
  // Print the data that we received
  socket.on('data', function(data) {
     console.log('\nReceived: %s ',
     data.toString().replace(/(\n)/gm, ""));
  });
 
  // Stopping the server
  // by using the close() method
  server.close(() => {
     console.log("Server closed successfully");
  });
});
 
 
// Start listening on a specific port and address
// by using listen() method
server.listen(PORT, HOST, function() {
   console.log("I'm listening at %s, on port %s", HOST, PORT);
});
 
// Creating and initializing client
var client = tls.connect(PORT, HOST, options, function() {
   
  // Disabling TLS renegotiation for this socket
  // by using tlsSocket.disableRenegotiation() method
  client.disableRenegotiation();
  client.write("TLS renegotiation is disabled");
 
  client.end(() => {
    console.log("Client closed successfully");
  });
});

Ejecute el archivo index.js con el siguiente comando:

node index.js

Producción:

I'm listening at 127.0.0.1, on port 1337
Client closed successfully

Received: TLS renegotiation is disabled
Server closed successfully
