[2] Tor is a network which enables people to use the Internet anonymously (though with known weaknesses) and to publish content on "hidden services", which exist only within the Tor network for security reasons and thus are typically only accessible to the relatively small number of people using a Tor-connected web browser.

Since then, it has been maintained and developed by Giovanni Pellerano from the Hermes Center for Transparency and Digital Human Rights as part of the GlobaLeaks Project, with financial support from the Open Technology Fund.

[4] Rather than typical top-level domains like .com, .org, or .net, hidden service URLs end with .onion and are only accessible when connected to Tor.

Tor2web acts as a specialized proxy or middleman between hidden services and users, making them visible to people who are not connected to Tor.

[5] Since version 2.0, a privacy and security warning is added to the header of each web page it fetches, encouraging readers to use the Tor Browser to obtain anonymity.
