Enabling HTTPS in your Java server using a free certificate

Using HTTPS connections in web application client-server communication has grown to be more and more common nowadays. In fact, for some types of applications, it’s become a requirement. For example, if you want to use Geolocation API in a web app running in Chrome, you need to have HTTPS enabled. All big browser vendors require HTTPS if you want to use HTTP/2. Even your search rank in Google is higher, if you provide a secure connection. Besides, web app users today are expecting to see that green secure connection indicator in the URL bar. So how does one enable it? Luckily for you as a web app developer, making the web more secure means only a few easy steps, and it’s completely free when using a service called Let’s Encrypt.
