Certbot is a free automated client that obtains SSL/TLS certificates from Let's Encrypt, an open certificate authority, and deploys them to web servers. It simplifies the process of enabling HTTPS encryption for websites by automating certificate fetching and installation. Developed by the Electronic Frontier Foundation, Certbot supports most major web server platforms.
