Authentication & identity tools

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... Workflows you can run end-to-end and decode at every step: Issuance (OpenID4VCI) • In-time https://docs.igrant.io/docs/open... • Deferred https://docs.igrant.io/docs/open... • Dynamic https://docs.igrant.io/docs/open... Holding & presentation • Receive & store https://docs.igrant.io/docs/open... • Receive & present https://docs.igrant.io/docs/open... • Send & verify https://docs.igrant.io/docs/open... EU Business Wallet & payments • Owner ID https://docs.igrant.io/docs/euro... • Payment wallet attestation https://docs.igrant.io/docs/open... • Payment data confirmation https://docs.igrant.io/docs/open... • Passwordless login https://docs.igrant.io/docs/eudi... DCQL queries • Trusted authority https://docs.igrant.io/docs/dcql... • Age verification https://docs.igrant.io/docs/dcql... • ID alternatives https://docs.igrant.io/docs/dcql... • KYC https://docs.igrant.io/docs/dcql... • Transport pass https://docs.igrant.io/docs/dcql... • Loan / bank statements https://docs.igrant.io/docs/dcql... • Delivery / postal codes https://docs.igrant.io/docs/dcql...

What does an SD-JWT VC actually look like? A walkthrough with real disclosures

SD-JWT VC adds a lot of moving parts on top of plain JWT disclosures, key-binding JWTs, salt, and an issuer key resolution chain (x5c, jwk, did:key, did:jwk).

If you've never picked one apart byte-by-byte, paste any sample into the JWT/SD-JWT decoder we built and watch each piece light up:

https://docs.igrant.io/docs/devt...

It auto-derives the issuer key, parses every disclosure inline, and gives you one-click signature verification.

DCQL queries in production: 7 real verifier scenarios

DCQL (Digital Credentials Query Language) is the part of OpenID4VP that decides "what does the verifier ask for, and how flexibly?" The spec examples are great but skinny what does it look like when you wire it to real use cases?

We documented seven we run end-to-end:

Basic query with trusted authority https://docs.igrant.io/docs/dcql...

Age verification (claim set) https://docs.igrant.io/docs/dcql...

How are you debugging mdoc/CBOR credentials during ETSI Plugtests?

The ETSI EAA Plugtests are running through 1 June 2026 with focus on SD-JWT VC and ISO 18013-5. Curious what tooling everyone is reaching for when an IssuerSigned structure or COSE_Sign1 envelope doesn't decode cleanly.

Our team got tired of pasting CBOR into half-broken local scripts (or worse, online decoders that upload to a server), so we built a browser-only one:

https://docs.igrant.io/docs/devt...

It surfaces the IssuerSigned tree, COSE_Sign1 protected/unprotected headers, the Mobile Security Object, every namespace, and the issuer x5chain.
