An Ed25519 private key consists of a 32 byte seed (from which you can
cheaply derive the 32 byte private scalar and the 32 byte hash prefix) and
the 32 byte public key.
This is actually what I tried, but I think I need to look at the
implementations to make it work. I can likely figure the golang out if I
need to, or probably there's a more direct approach to the whole shebang.
Maybe I'll come up with a high latency message to send to your offline
system =)
