April 2026: Delivered robust zero-length input support across AES, HMAC, and related primitives with spec-compliant no-deref behavior, added extensive zerolen tests and tooling, improved AVX/architecture detection (including AVX512 type 2 flag) with safe fallbacks, and enhanced Windows build reliability by increasing path length to 512. Implemented security-focused cleanup in AES-GCM state and improved IV handling for zero-length messages under no-check APIs. Result: improved reliability, portability, and performance on AVX-enabled platforms and Windows builds.

March 2026 — intel/intel-ipsec-mb: Delivered AES-CFB decryption performance optimizations by implementing optimized assembly routines that eliminate false store-to-load operations and reduce binary size. This work is captured in commit 037c12a18ad8573b3483f246b27ae33e64ba4ec2 (sse: [AES-CFB] false store to load elimination and reduce binary size), co-authored by Armon Chojnacki. No other major bugs reported this month for this repository. Overall, the changes improve cryptographic throughput and reduce memory footprint on Intel platforms, aligning with performance and footprint targets for IPsec workloads.

February 2026 focused on delivering a high-impact performance optimization in OpenSSL's ML-DSA path by introducing AVX2-accelerated NTT operations with runtime capability checks. Implemented forward/inverse NTT and NTT-domain polynomial multiplication using YMM registers, with Montgomery reduction, and added a robust runtime dispatch that falls back to portable C when AVX2 is not available. Built and integrated the AVX2 path across libcrypto and FIPS provider builds with conditional assembly inclusion to support target architectures. The feature shipped via a single, well-documented commit (3c07701bf542ddfcae2a9d5623fd68b33981fb78) merged March 11, 2026, following thorough reviews. Major bugs fixed for this area were not reported in the provided data; the work emphasizes performance, correctness, and broader platform support.

January 2026: Delivered targeted improvements across two critical codebases, with a focus on maintainability and cryptographic performance. In intel/intel-ipsec-mb, corrected documentation for CPU feature detection (SM4NI), ensuring accurate guidance for feature checks and reducing developer confusion. In openssl/openssl, implemented NTT multiply performance optimizations by refining data shuffling and removing unnecessary operations, with explicit impact across seven of eight levels. These changes collectively enhance cryptographic throughput and reduce future maintenance costs, supporting faster and more reliable secure communications.
