They say that the last Tor node presents all the information in clear.

If I want to send some sensitive information by Tor, could you encrypt it, and in this way be encrypted by both the Tor nodes, and by my encryption?

Is this possible?

    Setup an onion-pi and connect over the it. You are done.

  • I did not know about the existence of that device, but my question was about the last TOR node, that is, if I send a message only with the encryption that TOR gives me, then this message can be seen on the last node, but and If I send the same message, but with my own encryption, when I leave the 3 node it will no longer be "clear", because there is still an encryption layer, mine. Is this possible?

  • It is advisable to encrypt (an encryption other than TOR, so that it is not clear on the 3 node) the messages when I connect to TOR?

    If you send encrypted data into Tor, it will leave the final Tor node (the exit node) encrypted. The benefits of using HTTPS encryption with Tor has been discussed here.

    Think TOR as a proxy. It forwards what it gets. Encrypted data enters outputs as encrypted. Who the hell is going to break AES-256 while traveling on the TOR network?

They say that the last Tor node presents all the information in clear.

Whoever "They" are they are wrong or you did understand them wrong. The data are not necessarily in clear in the exit node but the additional encryption offered by Tor is removed.

Thus, if you send plain (unencrypted) data (like plain HTTP) then it will come out of the exit node as plain again. If you put encrypted data (like HTTPS) then it will come as encrypted out of the exit node. Of course, the endpoint you ultimately access needs to understand the additional protection you've added on top of Tor. Note that this is not only true for Tor but for other VPN too.

  • That "they" are people on the web who stress that the last node makes everything clear, but I understand, it's like a mirror, it returns you as is the object you give it. thanks man.
