Why would anyone ever use self signed certs? Buy a cheap ass domain, and use LetsEncrypt to get a free cert.

If it is for internal only, self signed is a lot easier.

Also probably no sysadmin uses it, but the Gemini protocol requires the use of a self signed cert

Hard disagree. As long as you have any machine with internet access it’s trivial, even more so if you can use DNS challenge.

You're absolutely correct. For self hosting at home I use cloudflare for DNS challenges.

Caddy is also amazing at making things even simpler.

So is using "pass" as the password to all of your sensitive systems. Still not best, or even good practice.

Are you conflating self-signed and untrusted?

Self-signed is fine if you have a trusted root deployed across your environment.

[–] [email protected] 4 points 1 year ago

Correct. If using actual pki with a trusted root and private CA, you're just fine.

I took the statement to mean ad-hoc self-signed certs, signed by the server that they are deployed on. That works for EiT but defeats any MitM protection, etc.
