Key-pair generator for Ed448 (RFC 8032). Only the SecureRandom from the supplied KeyGenerationParameters is used; the 57-byte seed is drawn directly from it.

Generate a fresh Ed448 key pair.

public virtual void Init(KeyGenerationParameters parameters)

Capture the SecureRandom that will source the seed.
