It provides an efficient and secure hashing primitive, which is able to exploit the parallelism of the implementation in a scalable way. It uses tree hashing over a round-reduced version of SHAKE128 as underlying primitive. This document builds up on the definitions of the permutations and of the sponge construction in {[}FIPS 202{]}, and is meant to serve as a stable reference and an implementation guide.}, }
