It’s relatively simple to get tor – as you can see from the above screenshot, you can simply visit torproject.org, and download it. It will have a version of tor for your operating system, and it will be a one-click install. Once you have it installed, you can get on the Deep Web by using the software appropriately.
What is Tor? Rather than post a lengthy explanation, I’ll refer you to both the documentation available at the tor project website, and wikipedia. For our practical purposes though it consists of two pieces of software. The first, Vidalia, creates your connection to the actual tor network and ensures that traffic from the second piece of software is routed over that connection. The second piece of software is a customised version of Firefox. The two work together to makes sure that your traffic is sent over that network and is not sent over your regular internet provider connection directly.
While no system is perfect, the multiple layers of encryption and the specialised routing inherent to the tor network make your browsing anonymous for all intents and purposes. However, to be secure you must make sure you follow the instructions on the site and make sure you keep up-to-date with tor releases. The NSA, in a program called “EgotisticalGiraffe” has been known to compromise users of the for network through vulnerable versions of Firefox.
In the glorious agorist future, all network connectivity will probably take place in a fashion similar to what tor uses now, if not all of them. This will ideally provide more redundancy (in the form of more mesh networking) as well as a reduction (if not elimination) of the infrastructure that makes it easy for organisations like the NSA and GCHQ to spy on people.
