Mégsem tudja text-be kikódolni:
"Perfect forward secrecy: In the original Onion Routing design, a single hostile node could record traffic and later compromise successive nodes in the circuit and force them to decrypt it. Rather than using a single multiply encrypted data structure (an onion) to lay each circuit, Tor now uses an incremental or telescoping path-building design, where the initiator negotiates session keys with each successive hop in the circuit. Once these keys are deleted, subsequently compromised nodes cannot decrypt old traffic. As a side benefit, onion replay detection is no longer necessary, and the process of building circuits is more reliable, since the initiator knows when a hop fails and can then try extending to a new node."
Gondoltak arra is, hogy támadások ellen védve legyen a hálózat.
Persze a legutolsónak ki kell tudni kódolnia, mert ő neki már kódolatlanul kell továbbítania.
