Very similar to a tool I built about a year ago! We've been using it with our 6-person team, and it's been working great. It uses a shared keyring.json to manage public keys, so we don’t have to duplicate the same keys across every repo.

It’s built on top of age for encryption (https://github.com/FiloSottile/age).
