The Tor network is a group of volunteer-operated servers that allows people to improve their privacy and security on the Internet. Tor's users employ this network by connecting through a series of virtual tunnels rather than makin g a direct connection, thus allowing both organizations and individuals to share information over public networks without compromising their privacy. Along the same line, Tor is an effective censorship circumvention tool, allowing its users to reach otherwise blocked destinations or content. Tor can also be u sed as a building block for software developers to create new communication too ls with built-in privacy features. This package contains the Tor software that can act as either a server on t he Tor network, or as a client to connect to the Tor network.
