Make sure you are connected to a server whose address starts with “ Web content scripts like JavaScript or Adobe flash will give away your anonymity.
If you are not using HTTPS, your traffic is still visible in two segments of the ride: from your computer to the entry node of the Tor network and from the exit node of the Tor network to the target server. Some situations where your anonymity gets compromised See that even if somebody intercepts the packet, a private key is still necessary for knowing the next hop in the Tor network.Ĥ.- Finally the exit node will decrypt the last layer with its private key and will send the data to the target server () The process will be repeated at each node until the packet reaches the exit node of its circuit. This decryption will reveal the next node IP address so the actual node will know where to send the packet forward. This entry node can decrypt the first layer of the onion by using its private key (which is only known by this particular node). It only has been wrapped as an onion to be sent through the wires.ģ.- Now the onion gets moving and arrives at the first node (entry node). At this point the data has not moved through the Tor network at all. The data will be at the centre of the onion and each layer will be one more layer of encryption for each Tor router this data has to go through.Įach layer of encryption is made with the correspondent router public key. The last node of the sequence is an exit node.Ģ.- In order to send a packet of data to an exit Node, the Tor client wraps this data in layers of encryption. The first Node of this sequence is an entry node. What do onions have to do with this? The way the data encryption takes place is comparable to the layers of an onion.ġ.- The Tor client or onion proxy constructs a random sequence of routers that belong to the Tor network.
Each time your browser communicates to facebook, the Tor client will create a different closed circuit. After retrieving the list of nodes, the client will build a closed and encrypted circuit from your browser to let's say. We first need a list of Tor relays or nodes that are retrieved by our Tor client automatically. Let's break down how the communication with a web server is established via TOR. Tor uses advanced cryptography to keep all communications private and the most important thing: It loses track of your identity while the information is passing through from your browser to the final destination (example ). It is a network of routers/relay servers operated by volunteers that allows users to remain anonymous while surfing the Internet. It is not a single router device as its name may suggest. Tor (The Onion Router) would be your best shot to stay anonymous on the Internet nowadays.
