  12. Description: anonymous communication system
  13. Tor is a connection-based low-latency anonymous communication system which
  14. addresses many flaws in the original onion routing design.
  15. .
  16. In brief, Onion Routing is a connection-oriented anonymizing communication
  17. service. Users choose a source-routed path through a set of nodes, and
  18. negotiate a "virtual circuit" through the network, in which each node
  19. knows its predecessor and successor, but no others. Traffic flowing down
  20. the circuit is unwrapped by a symmetric key at each node, which reveals
  21. the downstream node.
  22. .
  23. Basically Tor provides a distributed network of servers ("onion
  24. routers"). Users bounce their tcp streams (web traffic, ftp, ssh, etc)
  25. around the routers, and recipients, observers, and even the routers
  26. themselves have difficulty tracking the source of the stream.
  27. .
  28. Note that Tor does no protocol cleaning. That means there is a danger that
  29. application protocols and associated programs can be induced to reveal
  30. information about the initiator. Tor depends on Privoxy and similar protocol
  31. cleaners to solve this problem.
  32. .
  33. Client applications can use the Tor network by connecting to the local
  34. onion proxy. If the application itself does not come with socks support
  35. you can use a socks client such as tsocks. Some web browsers like mozilla
  36. and web proxies like privoxy come with socks support, so you don't need an
  37. extra socks client if you want to use Tor with them.
  38. .
  39. Remember that this is alpha code, and the network is very small -- Tor will
  40. not provide anonymity currently.
