Certbot

Certbot is a command-line client designed to automate the lifecycle of digital security certificates. By implementing the ACME protocol, it manages the communication between a local server and a certificate authority to verify domain ownership and issue transport layer security certificates without manual intervention.

The tool distinguishes itself through a modular plugin architecture that allows it to interact directly with various web server configurations and DNS providers. This framework enables the software to perform automated domain validation, modify server settings, and configure virtual hosts to establish encrypted connections.

Beyond initial issuance, the software provides automated renewal and persistent tracking of certificate lifecycles, private keys, and configuration history. It functions as a comprehensive utility for web server security hardening and the management of public key infrastructure across distributed environments.
