by
Two free, browser-based decoders for EUDI Wallet and EU Business Wallet developers: • mdoc CBOR Decoder (new): Inspect ISO/IEC 18013-5 IssuerSigned structures: COSE_Sign1 issuer authentication, the Mobile Security Object, namespaces, and x5chain certificates. • JWT / SD-JWT Decoder (enhanced): Parse headers, payloads, signatures, SD-JWT disclosures, and key-binding JWTs. Issuer keys auto-derived from x5c, jwk, did:key, or did:jwk for one-click verification.

Hey Product Hunt 👋 I'm George Padayatti from iGrant.io. ETSI EAA Plugtests are live (4 May – 1 June 2026), focused on SD-JWT VC and ISO 18013-5. Debugging credentials meant pasting CBOR into broken scripts or dropping sensitive data into random decoders. So we built our own. Three free, 100% browser-based tools — nothing leaves your machine: • mdoc CBOR Decoder — https://docs.igrant.io/docs/devt... • JWT / SD-JWT Decoder — https://docs.igrant.io/docs/devt... • QR Code Generator — https://docs.igrant.io/docs/devt... They pair with our Organisation Wallet (full issuer/verifier stack for EUDI + EU Business Wallets): https://docs.igrant.io/docs/orga...
