I don't know about LUKS, but for SSH the general consensus is that
key size does not really matter _if_ you use elliptic curves.
That is why I always use `ssh-keygen -t ed25519`. However, for more than
10 years know ed25519 is *still* not supported with Windows, which
means if you rely on your key being usable on Windows, you will
need to use the default RSA and in this case, key size still matters.
