I request the community to review a patch for enhancing CounterMode.crypt() for AES. This patch defines intrinsic for CounterMode.crypt() to leverage the parallel nature of AES in Counter (CTR) Mode.
This is achieved by operating on 6 blocks in parallel to issue independent x86 AES-NI instructions and keep the CPU pipeline full.
Testing on micro-benchmark has shown a speedup of 4x-6x.
