24)     obfsproxy is a tool that attempts to circumvent censorship, by
25)     transforming the Tor traffic between the client and the
26)     bridge. This way, censors, who usually monitor traffic between the
27)     client and the bridge, will see innocent-looking transformed
28)     traffic instead of the actual Tor traffic.

34)     obfsproxy supports multiple protocols, called <a href="<page docs/pluggable-transports>">pluggable
35)     transports</a>, which specify how the traffic is transformed. For

36)     example, there might be a HTTP transport which transforms Tor
37)     traffic to look like regular HTTP traffic.

41)     Even though obfsproxy is a separate application, completely
42)     independent from tor, it speaks to tor using an <a

44)     protocol</a> to minimize necessary end-user configuration.

58)     We've made an experimental package that currently works in all censored

59)     countries with no config changes.

62)     <p>Note that these bundles <b>are not maintained currently</b> &mdash;
63)     for example, they include DNS leaks and old insecure versions of Firefox.
64)     We're working on automating the build process. Stay tuned!</p>
