Note : Just keep in mind that the entire connection between the nodes and John’s onion proxy uses TLS and a session key alongwith a checksum for integrity checks that is negotiated between the OR’s and OP.the browser and the first node through which the traffic has to be relayed.The nodes are nothing but random routers or servers that relay the traffic by encrypting and decrypting the traffic going through them.All the data is sent in fixed size cells of 512 bytes across the onion routers , each cell contains some header and a payload that is encrypted when it goes from john’s Tor browser to the first node.īut before sending this uniquely crafted packet a circuit has to be established between the Tor client and the first onion node.

Let’s s say john has opened up his Tor browser and tries to access deep web, in that case first a circuit is setup between the onion proxy i.e. In the entire onion routing process that is implemented within Tor, there are few things that should be clear.When a user tries to use tor browser or onion proxy then a circuit is formed between the various relays or onion routers and the tor client(browser).It will be explained in more detail below.
