What if I let some identification information (like a page with my real name) leak in a plain http connection and the exit node captures this? Until when it be able to identify me? Till I change the circuit? Will it be able to identify me if I use it again another day? Will I have to generate another public key? (or does tor does this every time I start it?
Also, will the exit node be able to associate my identity with relay (does Tor uses different keys for my relay/hidden services?)
