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.
If you’re a developer for an important open source project, they might.
Attacking the xz project wasn’t done because the attacker cared about anything that the xz maintainer had. It was because he was trusted and the software he maintained had been given a fair bit of trust by certain maintainers and could be compromised and used as a vector into other systems that indirectly relied on that open-source project.
