The objective of Certbot, Let's Encrypt, and the ACME (Automated Certificate Management Environment) protocol is to make it possible to set up an HTTPS server and have it automatically obtain a browser-trusted certificate, without any human intervention. This is accomplished by running a certificate management agent on the web server.

This agent is used to:

- Automatically prove to the Let's Encrypt CA that you control the website - Obtain a browser-trusted certificate and set it up on your web server - Keep track of when your certificate is going to expire, and renew it - Help you revoke the certificate if that ever becomes necessary.

This package contains the main application, including the standalone and the manual authenticators.
