easy-rsa VS ubios-cert

Easy-rsa to the rescue. Been using it for a while, works great and makes life easier :)

Link: https://github.com/OpenVPN/easy-rsa

Summary from that page:

easy-rsa is a CLI utility to build and manage a PKI CA. In laymen's terms, this means to create a root certificate authority, and request and sign certificates, including intermediate CAs and certificate revocation lists (CRL).

No, OpenVPN relies on the CA trust model. Anyone signed by the CA has access, unless they have been revoked (CRL): https://github.com/OpenVPN/easy-rsa/blob/master/doc/EasyRSA-Renew-and-Revoke.md

Then make do with the CLI. There might be some tooling to help you, e.g. https://github.com/OpenVPN/easy-rsa

Hey folks. I'm one of the authors for Mastering OpenVPN, the author of Troubleshooting OpenVPN, and the maintainer of EasyRSA. In light of Apollo and other 3rd party apps going dark on the 30th, I figured I'd "turn in my notice" on Reddit and do the normal sysadmin data dump/brown bag before I'm gone. I've really enjoyed this group and hope things get sorted in the long run.

Correct. That applies to OpenVPN. There's a tool that OpenRSA maintains that help with creating those certificates, EasyRSA: https://github.com/OpenVPN/easy-rsa

Regarding the keys, csr and certificates it's pretty easy to manage them with easy-rsa (https://github.com/OpenVPN/easy-rsa)

$ git clone https://github.com/OpenVPN/easy-rsa.git

Depending on your use case, either https://github.com/FiloSottile/mkcert or https://github.com/OpenVPN/easy-rsa

If you can add CAs to the hosts that will access this server, you can be your own certificate authority. mkcert is good, as mentioned elsewhere, or you can go all out: https://github.com/OpenVPN/easy-rsa

Firstly, I used the tool ubios-cert and the installation instructions they provide to do the majority of this process. For a good number of DNS API providers, these instructions alone are sufficient (e.g. GoDaddy, Cloudflare, etc.).

ubios-cert got a major rewrite to get rid of firmware V1.x requirements (like podman) and now runs on the bare metal firmware V2.x+ for UniFi consoles.

And I wouldn't recommend waiting for it. In the meantime, you could try out or contribute to https://github.com/alxwolf/ubios-cert.

Highly recommend using alxwolf’s script if you already have a domain name. This runs locally on the UDM and automatically renews the certificate with letsencrypt or others. Works very well and is compatible with UnifiOS v2+.

You should check out one of the other projects linked in the Unifi-utilities repo, https://github.com/alxwolf/ubios-cert. I just used this one of my updated UDM Pro without a problem.

This is the one I was talking about. https://github.com/alxwolf/ubios-cert
