Certbot is a fully featured, easy-to-use and extensible client for Let's Encrypt CA. Let’s Encrypt is an open certificate authority founded by EFF, Mozilla and others. Browsers can then use this certificate to verify the identity of web servers and ensure secure communication across the web. Creating and managing a certificate is usually a lot of effort, but with Certbot and Let’s Encrypt it is automated. With just a few commands you can enable and manage HTTPS. The Certbot works directly on the web server. Please ask your hosting provider if Certbot can be used.
