SD-JWT inspector

Decode an SD-JWT or SD-JWT VC, resolve its disclosures, check its claims and Key Binding JWT, and verify its signatures. RFC 9901, with or without Key Binding

Everything stays in your browser. All parsing and checks run on this page, and nothing you paste, drop or check is sent to a server. The page only makes a request when you fetch a URL or check a signer against the EU List of Trusted Lists, and your browser sends it straight to that URL. A link to a result holds the input after the #, which browsers do not send to a server.

Verification

A JWK, a JWK Set, or certificates as PEM. Without it, the signature is verified with the x5c of the header; give the certificate of a trust anchor to check the x5c chain as well. The Key Binding JWT is verified with the key in cnf.
