示例 1: 文件名:index.js

java 描述语言

// Node.js program to demonstrate the
// tlsSocket.getEphemeralKeyInfo() 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 object containing information
  // regarding EphemeralKey by using
  // tlsSocket.getEphemeralKeyInfo() method
  value = client.getEphemeralKeyInfo();

  client.write("EphemeralKey : " + value.name);

  client.end(() => {
    console.log("Client closed successfully");
  });
});

使用以下命令运行 index.js 文件:

node index.js

输出:

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

Received: EphemeralKey : X25519
Server closed successfully

示例 2: 文件名:index.js

// Node.js program to demonstrate the
// tlsSocket.getEphemeralKeyInfo()  API
var tls = require('tls'),
    fs = require('fs'),

// Port and host address for server

// Private key and public certificate for access
var options = {
  key: fs.readFileSync('private-key.pem'),
  cert: fs.readFileSync('public-cert.pem'),

// Creating and initializing server
var server = tls.createServer(options,

  // tlsSocket.getEphemeralKeyInfo() 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")
  });
});

使用以下命令运行 index.js 文件:

node index.js

输出:

I'm listening at 127.0.0.1, on port 1337
client is connected
Received: EphemeralKey : null
client closed successfully
Server closed successfully
