[tor-dev] How do Ed25519 relay IDs look like?

That is because tor drops trailing '=' from base64 encoded values
within descriptors. Some fields indicate this within the spec, others
don't.

Gotcha. The name of 'identity' makes me wonder how this relates to
relay fingerprints, which are the canonical identifier we use.

Regardless, the more we can standardize the terminology we use the
less confusing these fields will be.
