Hi Nick,

Suggestion: Add a field to hold the Ed25519 Identity of the relay being

measured.  Say that implementations SHOULD include both RSA fingerprint

and Ed25519 identity, and that implementations SHOULD accept lines that

contain at least one of them.

Suggestion: the ed25519 IDs should be base64 encoded, without a trailing =, because a trailing = makes the format ambiguous.

You're talking about the certificate, right?.
This would change the concept of "line", since the certificate is more
than one "line".

This is how it is defined in dir-list-spec.txt

base64-encoded-ed25519-identity :== "-----BEGIN ED25519 CERT-----" NL
   certificate "-----END ED25519 CERT-----" NL

The certificate is a proof of identity.

But we only need to refer to a relay by its ed25519 public key:

"master-key-ed25519" SP MasterKey NL

[At most once]

Contains the base-64 encoded ed25519 master key as a single
        argument.  If it is present, it MUST match the identity key
        in the identity-ed25519 entry.
