July 2026 monthly highlights focusing on business value and core technical achievements across the walt.id identity stack. Key features delivered: - AWS KMS multi-region key management (WAL-1107): Implemented replica creation across multiple regions, cascade delete, and cross-region failover with failover configuration options. Updated crypto operations (signRaw, verifyRaw, getPublicKey) to use region failover and added a FailoverKmsClient wrapper. Added logging observability for KMS operations and updated test/build infrastructure. - OpenID4VP conformance test infrastructure: Built and enhanced conformance test infrastructure, wallet test plans, and runner orchestration for OpenID4VC/VP stacks, including adapter patterns and documentation. Established test profiles for VCI Issuer, VP Verifier, VCI Wallet, and VP Wallet with initial results and blocking issues documented. Major bugs fixed: - Replica creation/deletion reliability: Corrected replication flow to consistently call ReplicateKey from the primary region, expanded retry/backoff for eventual consistency, and ensured deletion handles null deletionDate/state. Result: all multi-region tests pass and AWS integration tests stabilize. - Alias/creation rollback handling: Introduced KeyAlreadyExistsException handling, rollback path for key creation failures, and 409 Conflict mapping for user responses; added serialization fixes for KotlinLogging to avoid persistence errors. - Validation and config safety: Added pre-call validation for multi-region configuration, removed hardcoded region lists, and ensured replica regions do not duplicate the primary region; failoverOrder validation aligned with actual region set. - Test infrastructure polish: Enabled AWS tests via RUN_AWS_TESTS flag, corrected test package paths, and improved test plan creation and reporting in conformance runners. Overall impact and accomplishments: - Strengthened multi-region resilience and data safety for cryptographic keys, reducing risk of single-region outages and enabling faster regional failover. - Accelerated time-to-value for customers requiring compliant, HA OpenID Connect deployments with validated conformance coverage and clear guidance. - Improved developer experience through better logging, error handling, and serialization reliability, plus streamlined CI/test workflows for AWS-backed features. Technologies/skills demonstrated: - AWS KMS, multi-region orchestration, cross-region failover, retry/backoff strategies, and observability (logging) in a distributed crypto scenario. - Kotlin/Java ecosystem, Gradle, KotlinLogging, and AWS SDK integrations. - OpenID Foundation conformance testing, test runners, adapters, and documentation practices. - Defensive programming with configuration validation, robust rollback, and error-handling patterns.
