Since the beginning of this year, Let’s Encrypt rolled out a new shortlived profile for certificates that make them valid for only 160 hours. The intention, as they say, is to encourage automation and reduce the window of certificate compromise (because revocation is somewhat a flakey thing).
Yet, I haven’t seen a lot of news about it since then. Hence the question: is this shorter cert thingy something you considered and deployed for your homelab?
As for me I’ve set up lego-acme with profile: "shortlived" on my rig. Lego runs on a bihourly cronjob, but only renews when a cert has >=3 days to expiry. It’s been pretty much a set-and-forget experience, although some more monitoring would be nice.
Everyone in here taking about an the automations they’ve done for certs and I just use Caddy. It handles all that for me.
Caddy is a good piece of software.
I’ve been using Nginx for 20 years and don’t really have a reason to switch, so I’m still using it. I use certbot, so it’s just one command to create the certificate initially, and then it auto-renews automatically via a systemd timer.
