Research direction

The issue names Keccak and raw-SHA3 but does not identify files, tests, or implementation entry points. Begin by locating those implementations and existing SIMD support, then determine the scope for AVX2 and AVX512 and how any change to the project's pseudo-intrinsics would be evaluated.
