That's what Rich said: "X25519 is a key-exchange-only algorithm". The
shared secret that drops out of the x25519 key exchange is used to key
AES128/GCM (some hand waiving).

This is a different application. ed25519 is signing, not key exchange.
I'm not sure how to do it because I've never needed it. But keep in
mind Rich said: "OpenSSL doesn’t fully support Ed25519".
