Show HN: Auth intermediary that cannot authorize. By design

2 points

3 months ago

What if your auth system had no admin override?

I built an authorization intermediary that cannot authorize.

How it works: • Hashes requests (opaque, can't see payload) • Forwards to provider (stateless, can't make decisions) • Provider validates everything (exclusive authority)

The intermediary holds no signing keys. The provider holds the only pen. Compromise the intermediary = you get nowhere.

Run it. Fork it. Fuck it up. If you can get it to authorize without provider consent, I'd love to see how.
