easy-rsa VS Pomerium

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 Anyone signed by the CA has access, unless they have been revoked (CRL): https://github.com/OpenVPN/easy-rsa/blob/master/doc/EasyRSA-Renew-and-Revoke.md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

Option 3: Pomerium might be an alternative as well.

That is not how you do Zero Trust. You want to use an Identity Aware Proxy. There are lots of ways you can implement this with Google as your core auth. For example Pomerium or oauth2-proxy.

I’m really surprised this sub has no love for Pomerium. I feel like it’s as simple as Caddy with all the security benefits of Traefik.

I am not sure if I understand how Pomerium works (or any identity-aware proxy).

Pomerium sidecar.

Just want to drop https://www.pomerium.com/ here. We use it at our company with ~1500 people with many apps behind the proxy. It also supports JWT for the backend, so you can integrate your apps easily without having to worry about the OAuth flow and also your apps are protected from random internet attacks.

You’ve got to protect. Anonymity is not going to work. Pomerium is another option in addition to those already suggested. https://github.com/pomerium/pomerium

I am currently looking at Wireguard/Tailscale (Wireguard based) options - early days for me so far. Also planning to look at something like Pomerium for a zero trust approach. https://www.pomerium.com/
