I'm looking for up-to-date information on Tor encryption standards, and I can't seem to find anything newer than 2013.
Everything I've been able to find links back to a proposal to move to Ed25519 keys: https://lists.torproject.org/pipermail/tor-dev/2013-August/005259.html
Poking around in my own Tor relay, I found a master public and master secret ed25519 key, along with a signing cert and signing secret key. However, there's also a secret_id_key and a couple of secret_onion* keys that are RSA private keys.
Does Tor 2.7 use Ed25519, or 1024-bit RSA? Why are there 2 kinds of keys? How secure is Ed25519 compared to 1024-bit or 2048-bit RSA?
Thanks in advance,
