Self hosted SSH key repository? (lemmy.chiisana.net)

I have too many machines floating around, some virtual, some physical, and they're getting added and removed semi-frequently as I play around with different tools/try out ideas. One recurring pain point is I have no easy way to manage SSH keys around them, and it's a pain to deal with adding/removing/cycling keys. I know I can use AuthorizedKeysCommand on sshd_config to make the system fetch a remote key for validation, I know I could theoretically publish my pub key to github or alike, but I'm wondering if there's something more flexible/powerful where I can manage multiple users (essentially roles) such that each machine can be assigned a role and automatically allow access accordingly?

I've seen Keyper before, but the container haven't been updated for years, and the support discord owner actively kicks everyone from the server, even after asking questions.

Is there any other solution out there that would streamline this process a bit?

It's such an underrated feature. It baffles me how people immediately turn to overly complicated solutions solving a problem they don't really have to solve, just because everyone assumes the only way is the default commonly known way. Like OP, people immediately jump to the conclusion you need extra software to manage the keys, rather than using another authentication method natively supported, and keep filling their known_hosts file with junk, making the whole validation process useless because everyone just accepts whatever key the host presents.

It's amazing how simple it is. Developer needs temporary access to debug a web server? Sure, here's your 2h valid cert to log in as the web user on the server, don't even need to actually log into the server to put their key in and then remove it. I mint a cert and it's ready to go on whichever users and servers I specified in the cert. Can't even gain persistence because regular authorized_keys is disabled and we have limited session durations.

I regularly leave people baffled at work because I come up with a clever and built-in super simple solution to something they expected to just slap more scripts and software to work around the only way they know to use the software. Read your manpages in full folks, it'll save you so much work. Know what your software is capable of.

That's a long rant, but your on point with it. I have a colleague who refuses to try new things cuz they don't understand that it makes life easier, I do tend to find the solutions that are simpler and easier to work
