May 2025: Implemented NanoTDF Policy Embedding Flexibility in opentdf/java-sdk. Added support for plaintext embedded policies alongside existing encrypted policies, with configurability to select policy type and updated encryption/decryption workflows to handle both formats. This improves interoperability and deployment flexibility for users integrating NanoTDF policies in Java-based workflows. No major bugs reported this month. Key impacts include faster onboarding for customers, broader policy deployment options, and a more robust, adaptable security policy layer.

March 2025 — Delivered EC-based key wrapping capabilities across opentdf/java-sdk and opentdf/otdfctl, enabling hybrid EC encryption schemes and configurable algorithms. Implementations introduced functional options for wrapping key algorithms and session key types, plus new CLI flags to specify EC curves. Updated documentation and end-to-end tests to validate EC-wrapping flows. Result: enhanced security, interoperability, and flexibility for customers deploying EC-based key management; aligned SDK and CLI behavior for consistent encryption workflows.

January 2025 (2025-01) monthly summary for opentdf/web-sdk. This period focused on modernizing TDF hashing/verification and improving manifest traceability by aligning with newer TDF specifications. The changes tighten integrity checks during encryption/decryption by leveraging binary data paths and removing hex encoding for segment hashes. A manifest update now includes the TDF spec version to improve cross-version compatibility and auditability. The work reduces risk of incompatibilities with downstream systems and simplifies integration with newer TDF-compliant deployments.

Monthly summary for 2024-11: Delivered CLI-based assertions support for opentdf/java-sdk, enabling runtime enforcement of conditions in TDF operations via JSON-configured assertions. Changes to Command.java added JSON parsing for assertion configurations, tying CLI input to runtime checks. No major bugs fixed this period. This work improves data integrity, reduces misconfig risk, and accelerates safe production rollout.

October 2024: Implemented configurable assertion verification in opentdf/java-sdk to provide deployment flexibility and potential performance relief. Added a disableAssertionVerification flag to TDFReaderConfig; updated loadTDF to honor the flag; introduced a dedicated test (testWithAssertionVerificationDisabled) to validate behavior. This work resolves issue #205 and was committed as 78d7b66e40bb52340e604ab645830287c91ba534. The change improves integration with external systems, reduces unnecessary verification overhead in trusted environments, and enhances overall test coverage.
