                    SHA-3 in C and x86 assembly

[ intro

If you're searching for a highly optimized implementation of SHA-3, the 
source code included here is not suitable since it has been written with 
instructions which cannot be executed in parallel on x86 CPU. 

The design of how blocks are processed also slows down computation so I 
would advise you look at an alternative library.

What this code does do is reduce the amount of space required but of 
course, it could be improved further. Since SHA-3 will be around for
many years to come, I will definitely work on improving the code to
reduce *size*

The code is public domain, feel free to do with as you wish.
