SD-JWT VC Decoder
Decode Selective Disclosure JWTs (SD-JWT / SD-JWT VC) — the EUDI wallet credential format. Splits issuer JWT, disclosures, and Key Binding JWT; verifies disclosure digests against the _sd arrays and the KB-JWT sd_hash, all in your browser.
Where SD-JWT VC is used
SD-JWT VC is the primary remote-presentation format of the EUDI wallet (PID, IBAN attestations, SCA with dynamic linking via the KB-JWT) and the credential model AP2 agent-payment mandates build on — compare the AP2 Mandate Decoder. The issuer JWT never contains hidden claims, only salted hashes: the holder chooses which disclosures to attach, and the verifier recomputes each digest. Signature verification against issuer trust lists is out of scope for this tool — it decodes and checks structure.
