How to generate the private key and public certificate?

Private key: Open notepad and copy paste the following key:

Now save the file as private-key.pem

Public certificate: Open notepad and copy paste the following key:

Now save the file as public-cert.pem

Example 1: Filename: index.js

JavaScript

// Node.js program to demonstrate the // http2session.setTimeout() method  const http2 = require('http2'); const fs = require('fs');   // Private key and public certificate for access const options = {   key: fs.readFileSync('private-key.pem'),   cert: fs.readFileSync('public-cert.pem'), };   // Creating and initializing server // by using http2.createServer() method const server = http2.createServer(options);   server.on('stream', (stream, requestHeaders) => {    // Getting session object   // by using session method   const http2session = stream.session;     // Haulting session for 3 secs   // by using setTimeout method   http2session.setTimeout(3000, () => {       console.log("Executed after 3 seconds");   })     // Stopping the server   // by using the close() method   server.close(()=>{     console.log("server destroyed");   }) });  server.listen(8000);    // Creating and initializing client // by using tls.connect() method const client = http2.connect('http://localhost:8000');   const req = client.request(   { ':method': 'GET', ':path': '/' });   req.on('data', (data) => {   console.log('Received: %s ',   data.toString().replace(/(\n)/gm, "")); });   req.on('end', () => {   client.close(() => {     console.log("client destroyed");   }) });

Run the index.js file using the following command:

node index.js

Output:

Executed after 3 seconds server destroyed

Example 2: Filename: index.js

JavaScript

// Node.js program to demonstrate the // http2session.setTimeout() API  const http2 = require('http2'); const fs = require('fs');  // Private key and public certificate for access const options = {   key: fs.readFileSync('private-key.pem'),   cert: fs.readFileSync('public-cert.pem'), };  // Creating and initializing server // by using http2.createServer() method const server = http2.createServer(options);  server.on('stream', (stream, requestHeaders) => {    // Getting session object   // by using session method   const http2session = stream.session;    // Haulting session for 1 secs   // by using setTimeout method   http2session.setTimeout(1000, () => {      console.log("Response after 1 second");   })    // Stopping the server   // by using the close() method   server.close(() => {     console.log("server destroyed");   }) });  server.listen(8000);  // Creating and initializing client // by using tls.connect() method const client = http2.connect('http://localhost:8000');  const req = client.request(   { ':method': 'GET', ':path': '/' });

Run the index.js file using the following command:

node index.js

Output:

Response after 1 second server destroyed
