February 2025 OpenSSL monthly summary focusing on performance optimization: Key feature delivered: AES-GCM performance optimization for ARM Neoverse N3 and V3, via architecture-specific unrolled paths implemented in armcap.c. Enabled unroll8/unroll12 to boost encryption/decryption throughput on affected CPUs. Commit: b6dceb36e8f46c7f74db5882322eda062227ab6e.

Month: 2024-12 — Delivered stabilized testing infrastructure and expanded test coverage for critical cryptographic paths in Mbed-TLS and PSA Crypto. Key features include removal of non-thread-safe TSAN interruptible ECC tests, addition of a test for invalid IOP key type handling, initialization and state tests for interruptible IOP key agreement, and alignment of test code and submodule references with external repositories to enable negative testing. Also fixed a missing abort path at the end of IOP key agreement and updated the PSA framework to support negative testing. These changes reduce race-condition exposure, increase robustness of key agreement flows, and improve release confidence through stronger test automation and framework integration.

November 2024 for Mbed-TLS/mbedtls-framework focused on hardening key agreement workflows: fixed a return-code handling bug, enabled export and validation of the generated key after successful key agreement, regenerated PSA Sim API headers and updated IO enums, and added restartable IOP key agreement support in PSA key exercise. These changes improve reliability, interoperability, and security posture, reduce test failures, and establish a solid foundation for production deployments.
