<p>
    obfsproxy is a tool that attempts to circumvent censorship, by
    transforming the Tor traffic between the client and the
    bridge. This way, censors, who usually monitor traffic between the
    client and the bridge, will see innocent-looking transformed
    traffic instead of the actual Tor traffic.

<p>
    obfsproxy supports multiple protocols, called <a href="<page docs/pluggable-transports>">pluggable
    transports</a>, which specify how the traffic is transformed. For
    example, there might be a HTTP transport which transforms Tor
    traffic to look like regular HTTP traffic.
    </p>

<p>
    Even though obfsproxy is a separate application, completely
    independent from tor, it speaks to tor using an <a
    href="https://gitweb.torproject.org/torspec.git/blob/HEAD:/proposals/180-pluggable-transport.txt">internal
    protocol</a> to minimize necessary end-user configuration.
    </p>

    <h2><a class="anchor" href="#download">Download Obfsproxy Tor Browser Bundle</a></h2>

<p>
    We've made an experimental package that currently works in all censored
    countries with no config changes.
    </p>

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