CertChain: X.509 Permission‑Driven API Auth

Users struggle with cumbersome login flows and mis‑authentications when generating API keys, and need fine‑grained control over who can act on their behalf. CertChain solves this by embedding permissions in X.509 certificate chains, letting developers issue and revoke API credentials without extra login steps while ensuring that only those with all required permissions can act.

Comment on: Disrupting supply chain attacks on NPM and GitHub Actions

I agree that benefits come from fine-grained permissions; however, for the fine permissions of user authentication (and API authentication), I think it would help to use X.509 certificate chains. The certificate can include a extension for specifying the permissions that it grants (a permission will only be granted if all certificates in the chain grant that permission). This avoids needing to login or use 2FA in order to set up new API keys or access tokens, and prevents problems with misauthentication with the wrong server (personal access tokens don't help much compared with passwords, but
