Pure Rust implementation of the FAEST digital signature scheme

FAEST is a digital signature algorithm designed to be secure against quantum computers. The security of FAEST is based on standard cryptographic hashes and ciphers, specifically SHA3 and AES, which are believed to remain secure against quantum adversaries.

This crate provides an implementation of FAEST written in Rust.
