The Shapeshifter project provides network protocol shapeshifting technology (also sometimes referred to as obfuscation). The purpose of this technology is to change the characteristics of network traffic so that it is not identified and subsequently blocked by network filtering devices.
There are two primary components to Shapeshifter: transports and the dispatcher. Each transport provide different approach to shapeshifting. These transports are provided as a Go library which can be integrated directly into applications. The dispatcher is a command line tool which provides a proxy that wraps the transport library. It has several different proxy modes and can proxy both TCP and UDP traffic.
If you are a tool developer working in the Go programming language, then you probably want to use the transports library directly in your application. https://github.com/OperatorFoundation/shapeshifter-transports
If you want a end user that is trying to circumvent filtering on your network or you are a developer that wants to add pluggable transports to an existing tool that is not written in the Go programming language, then you probably want the dispatcher. Please note that familiarity with executing programs on the command line is necessary to use this tool. https://github.com/OperatorFoundation/shapeshifter-dispatcher
If you are looking for a complete, easy-to-use VPN that incorporates shapeshifting technology and has a graphical user interface, consider Moonbounce, an application for macOS which incorporates shapeshifting without the need to write code or use the command line.
Protean is a collection of transformers designed for the purpose of obfuscating UDP network traffic.
This is a port of the Typescript implementation originally developed as a part of uProxy.
The overall goal of Protean is to provide transformations from UDP traffic into other UDP traffic, where the target UDP traffic has properties that resist network filtering. This is in contract to tools such as Shapeshifter Dispatcher, which provide resistance to network filtering by tunneling UDP traffic over TCP protocols.
Currently, Protean is provided as a library of open source transformation functions. A possible future goal is to integrate these transformations into transports for the Shapeshifter Transports library, with integration into Shapeshifter Dispatcher. Before this can happen, the Pluggable Transports specification needs to be updated to allow for UDP-to-UDP transports. Currently in the PT 2.0 specification, UDP is supported, but only in the case of UDP-over-TCP.
