Name : tor
Product : Fedora 27
Version : 0.3.1.9
Release : 1.fc27
URL : https://www.torproject.org
Summary : Anonymizing overlay network for TCP
Description :
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 making 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 used
as a building block for software developers to create new communication tools
with built-in privacy features.
This package contains the Tor software that can act as either a server on the
Tor network, or as a client to connect to the Tor network.
