certbot

Certbot is an open-source command line tool developed by the Electronic Frontier Foundation (EFF) that automates the process of obtaining and renewing SSL/TLS certificates. It simplifies the task of setting up HTTPS encryption for websites by providing an easy-to-use interface. Certbot supports several web servers, including Apache and Nginx, making it a versatile tool across different platforms.

The tool interacts with the Let's Encrypt certificate authority, which provides free SSL certificates to enhance website security and enable HTTPS. Certbot automates the domain validation, certificate issuance, and installation process, eliminating the need for manual steps. It also handles the renewal of certificates, ensuring that websites maintain secure connections. Certbot offers different authentication methods, such as HTTP-01 and DNS-01 challenges, to verify domain ownership during certificate issuance.

Certbot includes a wide range of options and features like automatic redirection from HTTP to HTTPS, support for multiple domains and subdomains, and the ability to configure advanced SSL/TLS settings. It provides detailed logs and error messages to troubleshoot any issues that may arise during certificate installation or renewal. Certbot can also be integrated with other tools or scripts for custom automation workflows.

Certbot is actively maintained and has a vibrant community contributing to its development. It is available for various operating systems and has detailed documentation, making it accessible for users with different levels of technical expertise. The tool focuses on providing a user-friendly experience while ensuring that websites have secure and encrypted connections via SSL/TLS certificates.
