I am doing a School project based on the in depth security of tor and i can't find the up-to-date security protocols the tor uses. i have found an old thread saying it uses RSA1024 for encryption but in another thread i found that tor wanted to mitigate to Ed25519-SHA-512 but i havent found more on that please could someone explain to me what protocols tor uses and what is the up-to-date encryption used?
i have found this https://gitweb.torproject.org/torspec.git/tree/tor-spec.txt but seems to be old?
