It loses a level of encryption at each node, but is never fully decrypted until it leaves the exit node for its destination.Įach node has an identifying IP address, which is also encrypted. Incoming traffic is rerouted in a similar manner.Ī simplified version of how Tor works (Source: EFF via Wikimedia)Īside from passing through several nodes, the traffic is encrypted, multiple times in fact. Your computer is connected to an entry node, and the final node traffic passes through is the exit node, after which it reaches its destination (the website you want to visit). When a user is connected to Tor (often through the Tor browser), their outgoing internet traffic is rerouted through a random series of at least three nodes (called relays) before reaching its destination (the website the user wants to visit). The Tor network, often referred to as just “Tor,” is a volunteer-run system that helps make internet use more anonymous. I’ll explain everything you need to know about Tor, including how anonymous it is, whether it’s legal, and if you still need to connect to a VPN while using Tor. In this post, I’ll ask (and answer) those questions for you. However, due to the negative associations many people make with Tor and related projects, it’s understandable that potential users are afraid to discuss their interest. It enables users greater anonymity online by encrypting internet traffic and passing it through a series of nodes.Ĭhances are, you have lots of questions about this project you’d like answered before you jump in.

The Tor Network (or just “Tor”) is an implementation of a program that was originally developed by the US Navy in the mid-1990s. If you’re interested in online privacy, then you’ve no doubt heard about Tor (The Onion Router).
