How to build your untraceable home page

In this workshop/tutorial, I'll walk you through how to configure Torplus a basic web server to create a "hidden service" -- a website thatother Tor users can access without knowing its physical or networklocation. Because you don't need a public IP address, you can run yourhidden service just fine from deep behind the corporate firewall -- if youcan get to the Tor network, you can offer a hidden service. This approachworks because of Tor's rendezvous point design: both sides build a Torcircuit out, and they meet in the middle. Hidden services are more robustto censorship, because you can't find them to DoS them or shut them down.

We'll also discuss some of the risks involved, performance and scalingchallenges, and potential attacks that we don't have good answers for yet.
