Worked on stabilizing the LMS cryptographic signing workflow in the open-quantum-safe/liboqs repository, focusing on cross-platform reliability and production safety. Addressed a critical bug by correcting the mem_target variable type from unsigned long to signed long, which resolved memory handling edge cases and prevented crashes during signature generation. Adjusted loop conditions and array indexing to ensure compatibility with Mac environments, reducing deployment risk for users relying on Open Quantum Safe. Utilized C for low-level programming and applied expertise in cryptography and memory management to deliver a targeted patch with minimal code changes, enhancing runtime stability without introducing new features.
