Walkthrough

Adds test support for binding a wallet public JWK and using a signed WLA JWT in delegated V2 biometric authentication. The test utilities resolve JWK and JWT placeholders, and the test configuration includes the key-binding and delegated authentication cases.

Changes

Wallet key binding and delegated authentication

Layer / File(s) Summary
Identity key-binding test setup
api-test/src/main/resources/ida/IdentityKeyBinding/*, api-test/src/main/resources/config/testCaseInterDependency.json, api-test/testNgXmlFiles/authSuite.xml
Adds the identity key-binding request and response templates and test configuration. Registers the test in TestNG and adds its prerequisite mappings.
Wallet JWK and WLA JWT resolution
api-test/src/main/java/io/mosip/testrig/apirig/auth/utils/IdAuthenticationUtil.java, api-test/src/main/java/io/mosip/testrig/apirig/auth/testscripts/BioAuth.java
Adds utility methods to resolve wallet public JWK and WLA JWT placeholders. BioAuth.test calls the JWK resolver before building the identity request and resolves JWT placeholders afterward when present.
Delegated biometric test with WLA JWT
api-test/src/main/resources/ida/BioAuthDelegatedV2/BioAuthDelegatedV2.yml, api-test/src/main/resources/ida/BioAuthDelegatedV2/BioAuthIdentityEncryptWithKBT.hbs
Adds a delegated V2 biometric test that submits a WLA JWT as a key-bound token and expects a successful KYC status. Adds its request template.

Merge Risk: 🟡 Moderate · up to f1e94

The new authentication tests can report a binding failure only in a later scenario, and can send an unresolved key placeholder. They can also log a short-lived signed token. Address these issues before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to f1e94

A newly signed, short-lived authentication token can appear in debug logs before the request is encrypted. The observed exposure is in test execution, not a demonstrated public service endpoint.

Retained concerns

  • Low · security · observed: The delegated test substitutes a signed WLA JWT before BioAuth logs the unencrypted identity request. With debug logging enabled, the test log can receive a usable credential.
Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is a signed credential for a named binding and supplied individual in test-runner logs. The reviewed caller path does not establish public service reachability; access to logs and any wider cache-sharing scope remain unknown.

Security Findings and Attack Paths

  • observed — The retained credential-exposure finding follows the new fixture’s WLA placeholder through JWT resolution to two full-request INFO log calls before encryption. An actor able to read those debug logs could obtain the short-lived signed token.

Trust Boundaries and Controls

  • observed — The binding request receives only the public JWK; signing uses the cached private key. Fresh signing, expiration, and failure on missing material constrain the token path, but request encryption does not protect the earlier log output.

Resilience and Maintainability Implications

  • inferred — Name-based retrieval links the binding certificate and wallet key, but the available implementations do not prove their common ownership, run isolation, or behavior under concurrent or repeated execution. This is an unresolved control question, not an established cross-identity compromise.

Hardening Proposals

  • proposed — Redact key-bound tokens before logging identity requests, including in debug mode.
  • proposed — Verify that the captured certificate and signing key belong to the same binding and that cached material is isolated or cleared between test runs.

- Around line 144-147: In BioAuth, replace both logger.info(identityRequest)
calls with logging that identifies the test case without including
identityRequest, so neither the injected WLA JWT nor its resolved individual ID
is written to logs.

- Around line 741-743: Update the ParseException catch around RSAKey.parse that
builds publicKeyJWK to rethrow the failure after logging, following the
fail-fast behavior of buildWlaJwt; do not allow the placeholder JWK to continue
to the binding request.

In
`@api-test/src/main/resources/ida/IdentityKeyBinding/IdentityKeyBindingResult.hbs`:
- Around line 3-5: Update the IdentityKeyBindingResult template so
identityCertificate is always included and validated as a required, non-empty
field, rather than being omitted when absent. Keep the existing
bindingAuthStatus and optional authToken handling unchanged.

Comment thread api-test/src/main/resources/ida/IdentityKeyBinding/IdentityKeyBindingResult.hbs Outdated
…mments

- BioAuth.java logged the raw identityRequest after the WLA JWT was
  injected into it, leaking a live 5-minute signing credential to logs
  when debug logging is enabled. Replaced both logger.info(identityRequest)
  calls with fixed messages naming the test case only.
- resolveWalletPublicJwk silently swallowed a failed RSAKey.parse, leaving
  publicKeyJWK as the unresolved literal token string and letting the
  binding request go out anyway to fail later with an unrelated server
  error. Now rethrows after logging, matching buildWlaJwt's existing
  fail-fast behavior.
- IdentityKeyBindingResult.hbs's identityCertificate assertion could never
  trigger since the YAML output never populated that key - a missing
  certificate would silently pass TC_IDA_IdentityKeyBinding_01 and only
  surface later as a JWT-build failure in TC_IDA_BioAuthDelegatedV2_48.
  Made it a required field in both the template and the YAML output.
- Trimmed the javadoc/inline comments added for the KBT feature down to a
  single one-liner in IdAuthenticationUtil.java.
