Ejemplo 1: Nombre de archivo: index.js
// Node.js program to demonstrate the // tlsSocket.getProtocol() 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() { // Getting tsl protocol version // by using tlsSocket.getProtocol() method value = client.getProtocol(); client.write("Protocol : " + value); client.end(() => { console.log("Client closed successfully"); }); });
Producción:
I'm listening at 127.0.0.1, on port 1337 Client closed successfully Received: Protocol : TLSv1.3 Server closed successfully
Ejemplo 2: Nombre de archivo: index.js
// Node.js program to demonstrate the // tlsSocket.getProtocol() method var tls = require('tls'), fs = require('fs'), // Port and host address for server PORT = 1337, HOST = '127.0.0.1'; // 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) { // Getting tsl protocol version // by using tlsSocket.getProtocol() method value = socket.getProtocol(); socket.write("Protocol : " + value); // 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() { console.log("client is connected"); }); client.on("data", function(data) { console.log('Received: %s', data.toString().replace(/(\n)/gm, "")); // Close the connection after receiving the message 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 is connected Received: Protocol : TLSv1.3 client closed successfully Server closed successfully
