I note two issues on how things are named in this draft:

1. The algorithm is named eddsa-sha256 (presumably by analogy to RSA), but
the primary key here is the curve size, not the hash, so it should be named
"eddsa25519" or "ed25519", as the keys themselves are not self-describing
except by looking at the length, which is ungood.

2. For the same reason, the key label in the DNS should probably be
"eddsa25519" or "ed25519".
