HAIP 1.0 OID4VP Verifier — conformance self-test results

Independent evidence that the CodeB EU Wallet Verifier passes the OpenID Foundation OID4VP-1.0-FINAL + HAIP-1.0-FINAL Verifier certification profile (alpha), executed by the OIDF-hosted conformance harness on 2026-07-19.

Self-test result on the OIDF alpha profile, not the OpenID Certified™ mark. Results generated by the OpenID Foundation conformance suite hosted at certification.openid.net. The OID4VP-1.0-FINAL + HAIP-1.0-FINAL Verifier profile is currently in alpha self-certification. Formal listing on the OpenID certified deployments page follows the OIDF submission process; this page attests that the exact EU Wallet Verifier shipped inside every CodeB tenant deployment passes the alpha suite end-to-end without failures or warnings. Formal submission is on the roadmap.

Summary

Area	What it verifies	Result
Happy path	End-to-end DCQL query, JAR, wallet response, JWE decrypt, SD-JWT VC parse, KB-JWT verify, claim mapping	Pass
Minimal `cnf.jwk`	Accepts holder-binding JWKs that carry only required fields (kty/crv/x/y), no optional metadata	Pass
Issuer signature integrity	Rejects VP whose SD-JWT issuer JWS signature has been tampered with	Pass
Key Binding JWT signature	Rejects VP whose KB-JWT signature fails to verify against the credential’s `cnf` key	Pass
Selective-disclosure integrity	Rejects VP where the KB-JWT’s `sd_hash` does not match the presented SD-JWT bytes	Pass
KB-JWT nonce binding	Rejects VP where KB-JWT `nonce` does not match the authorization-request nonce	Pass
KB-JWT audience binding	Rejects VP where KB-JWT `aud` does not match the verifier client identifier	Pass
KB-JWT time skew (past)	Rejects VP whose KB-JWT `iat` is outside the acceptable freshness window (1 year in the past)	Pass
KB-JWT time skew (future)	Rejects VP whose KB-JWT `iat` is outside the acceptable freshness window (1 year in the future)	Pass

How to reproduce

Sign up for a free account at certification.openid.net, create a plan of type “OID4VP-1.0-FINAL + HAIP-1.0-FINAL Verifier” (alpha) with variant credential_format=sd_jwt_vc and response_mode=direct_post.jwt.
Configure the plan’s server section with your CodeB tenant verifier metadata: the authorization endpoint URL, your per-tenant X.509 leaf public key, and your chosen client_id_prefix (both x509_hash and x509_san_dns are supported).
Run all 10 sub-tests. The verifier drives each end-to-end from wallet selection through decrypted-response claim delivery; no manual interaction is needed.
Download the certification package ZIP from your plan-detail page and compare per-test results arrays against the JSON bundle linked above.

Roadmap to the OpenID Certified™ mark

Passing the alpha conformance suite is step one. The full path to being listed on the OpenID Foundation certified-implementations page is:

Done — OID4VP-1.0-FINAL + HAIP-1.0-FINAL Verifier alpha suite, sd_jwt_vc + direct_post.jwt variant, zero-failure zero-warning run on the OIDF harness.
Next — run the same suite against the additional variants the profile allows (request_uri_method=post, mDL credential format) once the OIDF harness advances beyond alpha, and archive each plan.
Then — submit the plan IDs + OIDF certification fee to the OpenID Foundation using the process at openid.net/certification/instructions/. Listing typically appears within one to two weeks of submission.
Also on the plan — OpenID4VCI 1.0 Issuer certification for the credential-issuance side (tracked separately once OIDF publishes the corresponding Issuer conformance profile).
