WARNING!
Tor has many security issues!

Tor is an acronym for “The Onion Routerâ€. It is so named because it works by wrapping your request in several layers of encryption and then sending this request through an automatically generated chain of nodes. At some point, the request must be unwrapped to be sent to its final destination because most people are trying to communicate with an ordinary online service that doesn’t understand Tor’s methods.

The Tor node that performs the final unwrapping is called an exit node. The exit node decrypts the packet it received from its sibling on the chain of nodes and receives your full, plaintext request, which it submits on your behalf to the intended destination. The exit node waits for the response, encrypts it, and sends the encrypted response back up through the node chain until it reaches you, the dear user and the termination of the chain, where your Tor client decrypts the packet from your chain-sibling and presents your client with a comprehensible piece of data.

There is no way to restrict what an exit node can do with your session’s plaintext, and anyone can run an exit node. There is no qualification process and there are no restrictions. Barack Obama could be running an exit node within minutes, and so could Edward Snowden, and there’d be no way for either of them to ensure that the other couldn’t see the requests they were sending. The user simply checks a box in Vidalia and he’s running an exit node, relaying plaintext data between conversants. Exit nodes automatically change every few minutes, so many exit nodes will be relaying pieces of your conversation, possibly re-exposing sensitive data to many entities over the course of a single session. Anyone running a Tor exit node is a potential listener.

The Tor project attempts to scare exit node operators straight by citing the possibility of prosecution under wiretap laws, but this is a purely legal restriction; under Tor’s design, there is no possible technical implementation that would prevent the exit node operator from being able to save both incoming and outgoing messages as sent between conversants. Only the threat of prosecutorial pressure (which is basically non-existent for certain parties) stands betwixt an exit node operator and your data. Thus, Tor is extremely dangerous for the ordinary user. It must be used only for specific, carefully-planned sessions, or you risk exposing sensitive personal data to anyone running an exit node.

In principle, Tor is not very complex. It simply automates what would otherwise be a very cumbersome manual process of chaining proxies and encrypting a message for each proxy’s public key. Tor’s directories and announce mechanisms mean that one no longer must trawl for private proxies, but they also mean that anyone can register a node as a proxy and do whatever they like with the traffic they’re passing. Tor puts no restrictions on any of this — literally anyone running the Tor software can volunteer to pass along traffic and will automatically begin receiving the traffic of other users.
