The single round-trip initial Diffie-Hellman key exchange is susceptible to MITM attack, as has been demonstrated to me by a fan of the project. I'll be changing it to XX key exchange from libhydrogen. Either directly, or I'll use libsodium primitives to reimplement the same thing.

See if you can use this library instead of libsodium, as it'll probably work on your raspi zero: https://github.com/jedisct1/libhydrogen (Node bindings: https://github.com/trampi/node-libhydrogen-binding)

NIST's lightweight cryptography contest is still in progress. When it finishes I'd definitely change to whatever wins. In the iterim you might want to look into the candidates. I happen to like gimli, see libhydrogen for a good library that uses it.
