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.

Personal Opinion
Includes 39 encryption algorithms. Code looks clear, well written and efficient. So if you want to understand
