Comment (by nickm): The signature length IMO _needs_ to be unauthenticated, or we'll never be able to support another signature method with variable-length keys. Imagine if we were doing this with RSA instead of Ed25519: If we had to authenticate the signature length, we couldn't actually sign anything reliably, since we wouldn't know the signature length for sure until we had made the signature. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/20991#comment:5> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online _______________________________________________ tor-bugs mailing list tor-bugs@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-bugs
