Decode & inspect SPIFFE SVIDs

Paste an X.509-SVID (PEM certificate) or a JWT-SVID — the type is auto-detected. See the SPIFFE ID, trust domain, validity, and key, then a spec-cited grade of every structural check. 100% in your browser: no network, no server, nothing stored. SVIDs can carry sensitive identity, so they are decoded in this tab only. The signature is not verified — no trust bundle is provided.
