Tor is a software project that lets you anonymously browse the Internet. tor2web is a project to let Internet users access anonymous servers.
Here's how it works: Imagine you've got something that you need to publish anonymously, like the Federalist Papers or leaked video from a whistleblower. You wisely protect your anonymity using a Tor hidden service. Then people access those documents through tor2web; that way anyone with a Web browser can see them.
Whenever you see a URL like
http://duskgytldkxiuqc6.onion/, that's a Tor hidden Web service. Just replace
.tor2web.org to use the tor2web proxy network. Example:
This connects you with tor2web, which then talks to the hidden service via Tor and relays the response back to you.
WARNING: tor2web only protects publishers, not readers. As a reader installing Tor will give you much greater anonymity, confidentiality, and authentication than using tor2web. Using tor2web trades off security for convenience. (More details...)
HOST: You can set up your own tor2web proxy.
