  //TLS along with SSL is used for cryptographic protocols to secure communication over the web.
  //TLS uses public-key cryptography to encrypt messages.
  //In public-key cryptography, each client and each server has two keys: public key and private key.
  //Public key is shared by everyone while private key is secured.

  //require the tls module
  const tls = require("tls");
  
  //Properties and methods
  // 1. connect() - Returns a socket object
  let connect = tls.connect();
  
  // 2. createSecureContext() - Creates an object containing security details
  let css = tls.createSecureContext();
  
  // 3. createServer() - Creates a server object
  let create = tls.createServer();
  
  // 4. getCiphers() - Returns an array containing the supported SSL ciphers.
  let cipher=tls.getCiphers();
  console.log("Supported SSL ciphers",cipher);
