Since you are a Programmer, maybe this helps:

<https://crypto.stackexchange.com/questions/54353/why-are-nacl-secret-keys-64-bytes-for-signing-but-32-bytes-for-box>

Quote:

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 =)
