... avoid an AES implementation. I can see the reason why you do not
want AES, but in you may also use another established cipher which
requires less code size and can make use of already implemented hash
algorithms. Given that the keys to protect are small, what about using
the already implemented X25519 in place of a symmetric cipher?
