Certbot

Certbot is the tool that most site owners use to obtain and renew free certificates from Let's Encrypt for secure connections. This tag collects guides about keeping RSS and Atom feeds reachable over HTTPS. Articles explain how to serve the full certificate chain, confirm that renewal is scheduled and test it with a dry run. They also cover deploy hooks that reload the web server, challenge paths that must stay open and small scripts that watch the live expiry date. The advice helps site owners avoid silent outages and share every new article on social networks automatically.
