HARD HAT AREA

This repo is just my working notes on trying to implement SHA-3. Ultimately, I would like to come up with something that can get contributed to NSS.

The first iteration was to see how well I could do just from the spec, with just the optimizations that occurred naturally to me. That appears to have gotten performance to about 10x the NSS SHA-2 implementation (in terms of cycles/byte).

The next step is probably to try to improve performance. That will probably involve looking at the optimizations applied by the Keccak authors in their optimized implementation, and perhaps taking some techniques from the NSS SHA-2 implementation.

The measurement bits in speed_test.c are taken from the measurement code included with the C implementation distributed by the Keccak authors.
