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. 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. See the pluggable transports page for more information.
Even though obfsproxy is a separate application, completely independent from tor, it speaks to tor using an internal protocol to minimize necessary end-user configuration.
