![]() ![]() No one observing the traffic on the network can tell where the message came from or where it’s going.įigure 2. (New paths are created every time you create a message.) Since each relay transporting your message is aware of only two other nodes, your identity is protected. When you send an email, for example, the client application on your computer selects random relays in the network to create an untraceable path to the recipient. The Tor routing process is illustrated in Figure 2. The onion data structure protects messages with multiple layers of encryption to prevent the operators of the relays from reading the contents of the message. This prevents the operators of the relays from reading the contents of the packets.įigure 1. As the packet traverses the Tor network, each relay in the network decrypts (unwraps) a layer of encryption surrounding the packet. A data packet is first “wrapped” in layers of encryption. Onion routing got its name from the data structure, which resembles an onion, as shown in Figure 1. Today, Tor is used for a variety of purposes by the military, activists, journalists, and people like you. The US Navy created onion routing in 1998 for anonymous communication over a computer network. Tor uses a technique known as onion routing to conceal a user’s location and pass encrypted messages through a volunteer network of servers around the world. It’s a small step that can provide big peace of mind. ![]() This guide will help you get Tor up and running on your Mac to protect your privacy and safeguard the information you transmit on the internet. Install the free Tor client application on your computer to encrypt information transmitted to or from your Mac, bypass proxies, keep your physical location confidential, and conceal the identity of the sender and recipient. ![]() The nonprofit Tor project (short for The Onion Router) is a distributed network of volunteers who use their computers to route internet traffic anonymously. If this lack of privacy sends shivers down your spine, you’ll be happy to hear that there is a way to preserve your anonymity on the internet while using your Mac. Law enforcement officials, internet service providers, and even website administrators can find out what internet services and resources you accessed, when you accessed them, and what computer you used to access them with. Practically everything you do online with your Mac is logged and traceable back to your computer. This may be useful in countries that block Facebook, for example.AirPort Apple Apps Backups Developer Education Email Hardware Internet iPad iPhone Mac Music Network Photos Security TV Weekend Wonk This allows you to access Facebook through Tor, and your connection doesn’t ever leave Tor where it can be snooped on. It also means that someone hosting a website can hide that server using the Tor network, so no one can find it–in theory.įor example, Facebook maintains an official Tor hidden services address at “facebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd.onion”. This means that your browsing activity can’t be snooped on by someone watching the Tor exit nodes. A “.onion” address points to a Tor hidden service, which is a server you can only access through Tor. RELATED: Is Tor Really Anonymous and Secure?īut that means that “last mile” of traffic can be snooped on by an organization monitoring or even running the exit nodes–especially if your traffic is unencrypted. Google sees this as the exit node’s IP address contacting it instead of your IP address. That exit node then contacts for you, and it sends you back the data Google responded with. ![]() So, when you access through Tor, your request bounces from Tor relay to Tor relay before it reaches an “exit node”. When you connect to Tor, your internet activity is sent through the Tor network, anonymizing your Internet activity so it can’t be snooped on, and so that you can access websites that may be blocked in your country. It’s partially funded by the US government, and is designed to help people in countries where Internet access may be censored or monitored. Tor–short for “the onion router”–is an anonymizing computer network. RELATED: How to Browse Anonymously With Tor ![]()
