Browse anonymously relaying and encrypting your traffic, with Tor
Tor is a free, easy to use and portable program that will help you protect your privacy while you browse the internet. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location.
A typical proxy provider sets up a server somewhere on the Internet and allows you to use it to relay your traffic. This creates a simple, easy to maintain architecture. The users all enter and leave through the same server. Simple proxy providers are fine solutions if you do not want protections for your privacy and anonymity online and you trust the provider from doing bad things.
Tor passes your traffic through at least 3 different servers before sending it on to the destination. Because there’s a separate layer of encryption for each of the three relays, Tor does not modify, or even know, what you are sending into it. It merely relays your traffic, completely encrypted through the Tor network and has it pop out somewhere else in the world, completely intact. The Tor client manages the encryption and the path chosen through the network. The relays located all over the world merely pass encrypted packets between themselves.
Tor comes in a self-extracting executable that will create a new folder with all the files you need, including a bundled special version of Firefox. After Tor initializes its browser you can just start a safe surfing.
