[Servercert-wg] Ed25519 certificates

[Q Misell]

Hi all,

At the Tor meeting a few weeks ago I had some discussions with people
asking why Ed25519 certificates are not allowed under the BR (§ 6.1.5). As
far as I can tell there isn't much of a reason not to allow Ed25519 certs
(if a CA wishes to support them ofc) and there were a few scenarios
presented to me where Ed25519 certs would be useful in the context of Tor,
which already makes heavy usage of Ed25519 keys.

Would there be motivation to change the rules to allow Ed25519 certs, or is
there some reason I'm missing as to why they're not allowed?

Thanks,
Q Misell
