This way, censors who monitor traffic between the + client and the bridge will see innocent-looking transformed traffic + instead of the actual Tor traffic. + External programs can talk to Tor clients and Tor bridges using the <a +href="https://gitweb.torproject.org/torspec.git/blob/HEAD:/proposals/180-pluggable-transport.txt">pluggable +transport API</a>, to make it easier to build interoperable programs. + </p> + + <hr> + + <ul> + <li><b>Obfsproxy</b> is a framework for implementing new transport + protocols in C using libevent.
