This is a revised version of the original Tor PT obfsproxy (https://www.torproject.org/projects/obfsproxy.html.en).

We modified the ScrambleSuit to defend against Side-Channal attacks. The two side-channel features we are interested are: (1) packet size, (2) inter-packet delay. With a modified verison of Format-Transforming Encryption (FTE), we were able to transform Tor traffic into two target protocols. More debug and tests are needed. 

We strongly recommend the user to start with a standalone version of the PT in order to understand the design (https://github.com/iamfuyu1031/DoppelgangerProxy). Refer to the design paper in the repo (Stealthy Malware Traffic– Not as Innocent as It Looks.pdf).
