SSL for hardware devices that can't run certbot. (alien.top)

I realize that this topic has been beaten to death, but I've yet to come across a solution that will work for me.

I'm familiar with Let's Encrypt, which obviously works super well for it's intended use, but what about for services where you can't run certbot? eg: iDRAC, routers, switches, etc.?

I currently have a LE wildcard for my domain, which I use only locally (for now), but having to manually update the certs every 90 days for devices that can't run cerbot is a hard pass.

Is my only solution to this scenario to set up my own CA and go about it that way? If so, is there anything out there that will help assist the management of certificates and deployment of root certificates to clients? I know that this can be done via GPO, but I don't have a Windows computer on my home network.

I suppose another option would be to use a reverse proxy, but I would prefer to not have to go that route in this specific case if there are other options available.

Anyway, interested in what others are doing to address this.

You automate the sh*t out of it ... or at least as much as reasonably feasible.

E.g. I've often done script/programs that will easily and automagically install certs across many servers/devices of lots of different types and configurations, with just a single command. If you can do it manually from CLI, you can automate it.

I've also very well automated obtaining certs - again, simple quick command.

Combine those things and some reasonable checks/monitors/reminders or whatever else, and you've got something that's fully automated to do it all ... or at least pretty darn close.

yeah, I had not really played much with racadm and so I didn't even consider the possibility of being able to update certs using it.. as soon as I made that discovery, my life has changed. lol
