Tor Hidden Service Rendezvous Protocol

This simulator renders the mechanism that lets a Tor .onion service stay reachable without ever revealing its IP address: standing circuits to redundant introduction points, a client-chosen rendezvous point that splices two independent 3‑hop circuits together, and the self-certifying v3 address format derived from the service's own public key. Seize introduction points to watch reachability degrade and recover, rotate the rendezvous point to see session unlinkability in action, and regenerate the identity key to see the address change with it — all while live readouts confirm that no single relay in the session ever learns both real IP addresses.
