From eb31018b8946c150ea5c372ea4c35c160ccf6be3 Mon Sep 17 00:00:00 2001 From: Adam Burdett Date: Thu, 5 Mar 2026 10:17:31 -0700 Subject: [PATCH 01/31] feat(oid4vc): add mDOC (ISO 18013-5) credential issuance and verification Implements OID4VCI mso_mdoc credential issuance and OID4VP mDOC presentation verification using the isomdl-uniffi Rust library. Key changes: - Rewrite mso_mdoc credential processor with isomdl-uniffi bindings - Add mDOC issuer (mdoc/issuer.py) and verifier (mdoc/verifier.py) - Add MSO issuer/verifier (consolidated from mso/ into mdoc/) - Add key generation routes for mDOC signing keys - Add storage layer: trust anchors, certificates, keys, config - Add x.509 cert chain handling and PEM splitting utilities - Add trust anchor guard (fail-closed) and cert expiry validation - Remove superseded mso/ package and x509.py (merged into mdoc/) - Update Docker/CI to install isomdl-uniffi platform wheel - Add OID4VC conformance tests GitHub Actions workflow - Fix ConnectError retry in integration test credo_client fixture Signed-off-by: Adam Burdett --- .../workflows/oid4vc-conformance-tests.yaml | 149 +++ .../workflows/pr-linting-and-unit-tests.yaml | 2 - oid4vc/docker/Dockerfile | 124 ++- oid4vc/docker/dev-verifier.yml | 8 +- oid4vc/integration/tests/conftest.py | 13 +- oid4vc/mso_mdoc/DEEP_REVIEW.md | 478 +++++++++ oid4vc/mso_mdoc/README.md | 219 ++++- oid4vc/mso_mdoc/__init__.py | 163 +++- oid4vc/mso_mdoc/cred_processor.py | 780 ++++++++++++++- oid4vc/mso_mdoc/key_generation.py | 481 +++++++++ oid4vc/mso_mdoc/key_routes.py | 460 +++++++++ oid4vc/mso_mdoc/mdoc/__init__.py | 19 +- oid4vc/mso_mdoc/mdoc/exceptions.py | 25 - oid4vc/mso_mdoc/mdoc/issuer.py | 325 ++++--- oid4vc/mso_mdoc/mdoc/utils.py | 99 ++ oid4vc/mso_mdoc/mdoc/verifier.py | 917 ++++++++++++++++-- oid4vc/mso_mdoc/mso/__init__.py | 6 - oid4vc/mso_mdoc/mso/issuer.py | 120 --- oid4vc/mso_mdoc/mso/verifier.py | 60 -- oid4vc/mso_mdoc/routes.py | 235 ++++- oid4vc/mso_mdoc/storage/README.md | 50 + oid4vc/mso_mdoc/storage/__init__.py | 374 +++++++ oid4vc/mso_mdoc/storage/base.py | 52 + oid4vc/mso_mdoc/storage/certificates.py | 151 +++ oid4vc/mso_mdoc/storage/config.py | 57 ++ oid4vc/mso_mdoc/storage/keys.py | 167 ++++ oid4vc/mso_mdoc/storage/trust_anchors.py | 208 ++++ oid4vc/mso_mdoc/x509.py | 32 - 28 files changed, 5183 insertions(+), 591 deletions(-) create mode 100644 .github/workflows/oid4vc-conformance-tests.yaml create mode 100644 oid4vc/mso_mdoc/DEEP_REVIEW.md create mode 100644 oid4vc/mso_mdoc/key_generation.py create mode 100644 oid4vc/mso_mdoc/key_routes.py delete mode 100644 oid4vc/mso_mdoc/mdoc/exceptions.py create mode 100644 oid4vc/mso_mdoc/mdoc/utils.py delete mode 100644 oid4vc/mso_mdoc/mso/__init__.py delete mode 100644 oid4vc/mso_mdoc/mso/issuer.py delete mode 100644 oid4vc/mso_mdoc/mso/verifier.py create mode 100644 oid4vc/mso_mdoc/storage/README.md create mode 100644 oid4vc/mso_mdoc/storage/__init__.py create mode 100644 oid4vc/mso_mdoc/storage/base.py create mode 100644 oid4vc/mso_mdoc/storage/certificates.py create mode 100644 oid4vc/mso_mdoc/storage/config.py create mode 100644 oid4vc/mso_mdoc/storage/keys.py create mode 100644 oid4vc/mso_mdoc/storage/trust_anchors.py delete mode 100644 oid4vc/mso_mdoc/x509.py diff --git a/.github/workflows/oid4vc-conformance-tests.yaml b/.github/workflows/oid4vc-conformance-tests.yaml new file mode 100644 index 000000000..5fbfdb0b3 --- /dev/null +++ b/.github/workflows/oid4vc-conformance-tests.yaml @@ -0,0 +1,149 @@ +name: OID4VC Conformance Tests +# Runs the OIDF HAIP conformance suite against ACA-Py OID4VCI issuer and +# OID4VP verifier.

02/31] fix(mso_mdoc): replace _patch_mdoc_keys with Mdoc.issuer_signed_b64() The upstream isomdl-uniffi library now exposes issuer_signed_b64() which serialises directly to an IssuerSigned struct that carries the correct serde rename attributes for ISO 18013-5 section 8.3 camelCase keys (issuerAuth, nameSpaces) and array namespace values. This removes the Python-side _patch_mdoc_keys workaround which had to decode CBOR, rename keys by hand, and re-encode. The fix is now in the right layer (Rust serialisation types) rather than a post-processing hack. Change summary: - Remove import base64 (only used by _patch_mdoc_keys) - Remove _patch_mdoc_keys() entirely - Replace stringify() + _patch_mdoc_keys() call with mdoc.issuer_signed_b64() - Add test_mdoc_sign_emits_iso_cbor_keys to verify camelCase keys and array namespace values end-to-end through isomdl_mdoc_sign() Signed-off-by: Adam Burdett --- oid4vc/mso_mdoc/mdoc/issuer.py | 68 ++----------------- .../mso_mdoc/tests/test_mdoc_functionality.py | 57 ++++++++++++++++ 2 files changed, 62 insertions(+), 63 deletions(-) diff --git a/oid4vc/mso_mdoc/mdoc/issuer.py b/oid4vc/mso_mdoc/mdoc/issuer.py index e4e0f8f4f..7e85c9d82 100644 --- a/oid4vc/mso_mdoc/mdoc/issuer.py +++ b/oid4vc/mso_mdoc/mdoc/issuer.py @@ -18,7 +18,6 @@ credential format that follows the ISO 18013-5 mobile document structure.

The Rust layer does not enforce public-only JWK, so the private key becomes embedded in the MSO. - -**Fix:** Apply the same `{kty,crv,x,y}` allowlist stripping unconditionally before any serialisation of the holder key: -```python -def _strip_to_public_jwk(jwk: dict) -> dict: - return {k: jwk[k] for k in ("kty", "crv", "x", "y") if k in jwk} -``` - ---- - -### M-5: Legacy device-auth fallback silently relaxes holder binding - -**File:** `mso_mdoc/mdoc/verifier.py` — `_verify_single_presentation()` (~L490) - -When device authentication fails but issuer authentication succeeds, `verify_oid4vp_response_legacy` is tried silently.

But if the library emits both forms (transition release), `mdoc_map` would gain both keys and verification would pick the wrong one. - -**Fix:** Assert pre-conditions (either both old keys are present, or none are) and log the isomdl-uniffi version at startup: -```python -import isomdl_uniffi -LOGGER.info("isomdl_uniffi version: %s", getattr(isomdl_uniffi, "__version__", "unknown")) -``` -Remove the patch entirely once the minimum required isomdl-uniffi version emits camelCase. - ---- - -### M-9: `handle_proof_of_posession` typo - -**File:** `oid4vc/oid4vc/public_routes/token.py` - -Function name is misspelled (`posession` → `possession`).

Tue, 10 Mar 2026 15:53:23 -0600 Subject: [PATCH 24/31] mso_mdoc: enforce cert-at-key-generation invariant Store a self-signed certificate whenever a new signing key is generated in resolve_signing_key_for_credential (both the default-key path and the verification-method path), so every key always has a certificate on record. Replace the on-demand fallback in issue() and the mdoc_sign route handler with a hard CredProcessorError / ValueError: missing certificates are now a programmer error, not a silent auto-repair. Remove unused imports from routes.py (uuid, datetime, timedelta, generate_self_signed_certificate) that were only needed by the removed fallback block. Add tests: - TestResolveSigningKeyStoresCertOnGeneration: verifies a cert is stored for both generation paths and is NOT stored for pre-existing keys. - TestMissingCertRaisesCredProcessorError: verifies the hard error fires when get_certificate_for_key returns None. - Update TestResolveSigningKeyPersistsDefaultConfig to mock generate_self_signed_certificate alongside generate_ec_key_pair so the fake PEM string does not reach the real certificate builder.

Raise CredProcessorError with a clear message directing the operator to register the key via the key management API before issuing. Update tests: replace test_verification_method_key_generation_stores_certificate (which tested the wrong behaviour) with: - test_unknown_verification_method_raises: asserts CredProcessorError is raised and storage is not touched. - test_known_verification_method_returned_without_cert_write: asserts an existing VM key is returned immediately without writing a certificate.

Previously any run that loaded the env-var key for the first time would silently replace whatever key the operator had registered. Bug 2 - inconsistent storage API: Replace get_key (returns raw JWK only) with get_signing_key (returns the full record, consistent with every other call-site in _resolve_signing_key). Bug 3 - silent failure masked by misleading error: Replace bare except/log with re-raise as CredProcessorError with a message that names the failing file. Previously a bad PEM raised "No default signing key is configured" with no indication of why. Add TestStaticEnvVarKeyLoading with four tests that each expose one of the above bugs (plus the happy-path complement for Bug 1).

Private methods _prepare_payload and _normalize_mdoc_result remain as one-liner delegates to preserve the existing test API. Update 6 test patch paths from mso_mdoc.cred_processor.MdocStorageManager to mso_mdoc.signing_key.MdocStorageManager for tests of the standalone resolve_signing_key_for_credential function; update debug-log capture logger from mso_mdoc.cred_processor to mso_mdoc.payload.

Split into three focused modules: - trust_store.py: TrustStore protocol + WalletTrustStore - cred_verifier.py: MsoMdocCredVerifier + parsing helpers (PreverifiedMdocClaims, _parse_string_credential, _extract_mdoc_claims) - pres_verifier.py: MsoMdocPresVerifier + OID4VP helpers + mdoc_verify (extract_mdoc_item_value, extract_verified_claims, MdocVerifyResult) verifier.py is now a thin re-exporter for backward compatibility. Update all test patch targets to reference the new module paths: - mso_mdoc.mdoc.verifier.isomdl_uniffi -> cred_verifier / pres_verifier - mso_mdoc.mdoc.verifier.Config -> pres_verifier - mso_mdoc.mdoc.verifier.retrieve_or_create_did_jwk -> pres_verifier - mso_mdoc.mdoc.verifier.MdocStorageManager -> trust_store Tests that exercise mdoc_verify() also patch cred_verifier.isomdl_uniffi since _parse_string_credential lives there and holds its own module reference.
