Using the I can now choose which implementation of algorithm we can use for a specific task and how efficient are the optimization provided
The official keccak gives a list of several implementation (they can be found here https://keccak.team/software.html) The aim of this article is to evaluate them, try to optimize them and choose the fastest one.
The code can be found here https://sourceforge.net/projects/fehashmac/ .
Includes 39 encryption algorithms. Code looks clear, well written and efficient. So if you want to understand
