transports
A HTTP proxy that aims to support different transports.
Motivation
I started the facebook tunnel project two years ago and I thought that it could be better to follow a modular approach for supporting other services (chat systems, platforms, *gram, *book?).
This repository includes some code to explore the idea.
Why not a TCP/UDP tunnel?
At this time I'm not planning tuntap support (like I did in the previous project). I would like to focus on the transports. Also, I think that a HTTP proxy is easier to port and run, especially when considering that the project is built on Golang, where the output is a static binary. For example, it'll be very easy to build a binary for ARM.
Available transports
I've been working on these transports during the past week:
Facebook Transport (early stage, sorry!)
This transport uses surf, a stateful web browser built in Go.
Load your credentials by using export or the .env file:
[email protected]
FB_PASSWORD=supersecretpass
FB_FRIEND=yourtunnelfriend
I'm looking for collaborators from countries where the Internet.org campaigns like "Free Basics" are active, they could benefit from it :)
Whatsapp Transport (status: you can perform some GETs)
This transport uses a HTTP wrapper for yowsup to send/receive Whatsapp messages.
I recorded this small video, showing some interactions with this transport. For the demonstration I point my browser to the proxy and perform a test request to Akamai, the communication happens between two Whatsapp clients running on the same computer:
It would be good to have a "pure Golang" Whatsapp library but I think the current approach is fine for experimentation (anyone considering writing this?).
The following environment variables are used:
WA_CLIENT_LOGIN=123412341
WA_CLIENT_PASSWORD=whatsappgeneratedpassword123
WA_CLIENT_CONTACT=43214321
WA_SERVER_LOGIN=123412341
WA_SERVER_PASSWORD=whatsappgeneratedpassword123
Requires Python 3
Marshalers
I'm working on providing a set of "marshalers" and a simple API to combine them, this could be useful for conducting network/system usage benchmark experiments & performing a good choice.
Protocol buffers sound like a good option, instead of JSON (which is what I'm actually using for the Whatsapp transport). Also brotli looks promising. A combination of these two is a very interesting thing to consider.
Tor support
There's a Tor integration idea for the server side, I've did a few tests with it, under the following scenario:
The Whatsapp transport includes a flag to enable Tor (UseTor), I'm expecting to extend this flag to any transport.
The Tor support is achieved by overriding the default http.Transport dialer with a custom one.
Ideas/to-do
- Handle SSL.
- Extend the test coverage.
- Think about some way of debugging the transports/traffic.
- Run basic tests in additional platforms (e.g. ARM).
- Plan strategies for mobile support, Golang is doing great progress on this.
- Multiplexing
