not sure what you mean. Tor uses encryption to provide anonymity for TCP streams over a 3+ hop Tor circuit with authentication and privacy between each relay (onion layer).
I mean the data part. If you are sending email, the actual email content or if it is voice, the actual voice stream. Can we have an option where we can leave it to the end user to take care of its encryption. Since, we are using Onion routing we may not want the processor's spending encrypting and decrypting it 3+ times this user specific data. The TCP header maybe encrypted if it can somehow can violate anonymity but I am referring to its payload/data here. Or am I mistaken. Does Tor nodes not encrypt the payload? Thank you, Sarad

correct. Tor only encrypts from itself as client out to exit node. you must encrypt from client application to destination (end-to-end). best regards,
I think there was an article last year showing that by monitoring a lot of exit nodes, it was possible in many cases to determine who had sent the traffic. Meanwhile, a lot of users weren't encrypting, under the assumption that TOR was encrypting the last hop. As a result someone (I forget who) was able to see Embassy and other quite sensitive communications. Actually, since https is readily available, forcing TOR to encrypt that last hop would actually slow things down, possibly noticeably.
