During October 2025, Li Rui focused on improving the open-quantum-safe/liboqs project by addressing a critical issue in its performance benchmarking suite. He resolved a bug that caused incorrect signature length measurements in speed tests by passing the signature length as a pointer and ensuring correct dereferencing within the OQS_SIG_verify call. This C programming work enhanced the accuracy and reliability of benchmarking results, directly supporting better optimization decisions. Li Rui’s efforts in performance optimization and testing improved the credibility of speed-test data and strengthened the overall code health of liboqs, demonstrating careful attention to instrumentation and measurement precision in C.
