obfsproxy 0.2.13-2 (s390x binary) in ubuntu zesty

 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.
 .
 It is written in Python and is compliant with the Tor pluggable transports
 specification, and its modular architecture allows it to support multiple
 pluggable transports.
