Developed and contributed a vector-length agnostic Poly1305 implementation for AArch64 using SVE2 to the openssl/openssl repository, targeting improved cryptographic performance on ARM servers. The solution dynamically detects SVE2 support at runtime and selects the optimal execution path for vector lengths of 256, 512, 1024, or 2048 bits, ensuring efficient utilization of available hardware. Implemented in C and assembly, the work focused on low-level programming, cryptography, and performance optimization. Collaboration with OpenSSL maintainers ensured thorough code review and integration. This enhancement strengthened TLS throughput and optimized Poly1305 workloads across diverse ARM architectures, demonstrating depth in SVE2 vectorization.
