nodejs code to create end-to-end encrypted chat application

const crypto = require('crypto');
const net = require('net');

// Generate the key pair
const { publicKey, privateKey } = crypto.generateKeyPairSync('rsa', {
  modulusLength: 4096,
  publicKeyEncoding: {
    type: 'pkcs1',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs1',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'your-passphrase'
  }
});

// Create a server
const server = net.createServer((socket) => {
  console.log('New client connected');

  // Encrypt the data using the public key
  const encrypt = crypto.publicEncrypt(publicKey, Buffer.from('Hello, World!'));

  // Send the encrypted data
  socket.write(encrypt);

  // Decrypt the data using the private key
  const decrypt = crypto.privateDecrypt(
    { key: privateKey, passphrase: 'your-passphrase' },
    encrypt
  );

  // Log the decrypted message
  console.log(decrypt.toString());
});

server.listen(3000, () => {
  console.log('Server started on port 3000');
