<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 pluggable
    transports, 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.

    We've made an experimental that currently works in all censored
    countries with no config changes.
    <b>Please spread the news of these bundles to the right people,
    but please don't make a big media splash out of them &mdash; we need
    them to remain available and working for people in censored areas.</b>
