Hi, I was looking at private CAs since I don’t want to pay for a domain to use in my homelab.

What is everyone using for their private CA? I’ve been looking at plain OpenSSL with some automation scripts but would like more ideas. Also, if you have multiple reverse-proxy instances, how do you distribute domain-specific signed certificates to them? I’m not planning to use a wildcard, and would like to rotate certificates often.

Thanks!

Edit: thank you for everyone who commented! I would like to say that I recognise the technical difficulty in getting such a setup working compared to a simple certbot setup to Let’s Encrypt, but it’s a personal choice that I have made.

    I do realise the security problem in keeping the private key safe. I plan to use a VM with encrypted storage underneath. Do you think that’s OK for a homelab, or should I invest time into integrating HSM modules from Nitrokey?

        I would not like to use a public domain for my internal network. By extension, I do not want any public CA to know the domains and subdomains I use in my lab and home network
