Slitheen is a decoy routing system for censorship resistance. The source code consists of two parts: the client code (to be distributed and run on the machines of users wishing to circumvent censorship), and the relay station code (to be run on a relay station deployed by an ISP in the middle of the network).

If you have any questions about the code or installation, please contact Cecylia Bocovich <cbocovic@uwaterloo.ca>.


INSTALLTION INSTRUCTIONS:

For the client:
	- The client code consists of two parts: (1) an Overt User Simulator (OUS) that issues repeated requests to uncensored sites, and (2) a SOCKS proxy frontend that takes connection requests and data from the user's browser and feeds it to the OUS.

0. Building this system requires the following dependencies:
	apt-get install build-essential g++ flex bison gperf ruby perl \
	  libsqlite3-dev libfontconfig1-dev libicu-dev libfreetype6 libssl-dev \
	    libpng-dev libjpeg-dev python libx11-dev libxext-dev

1. Fetch all necessary git repositories:
	git clone git@git-crysp.uwaterloo.ca:openssl
	git clone git@git-crysp.uwaterloo.ca:phantomjs

2. Build our modified version of openssl
	cd openssl
	./config --prefix=../sslout --openssldir=../sslout/openssl
	make
	make test
	make install
	cd ..

3. Build phantomJS (Note: this takes a ridiculously long time)
	cd phantomjs
	./build.py
	cp bin/phantomjs ../client/
	
4. Obtain public key from relay station save file as pubkey in client/ directory

For the relay station:

0. Install dependencies
	apt-get libpcap-dev

1. Fetch necessary git repository:
	git clone git@git-crysp.uwaterloo.ca:openssl

2. Build openssl
	cd openssl
	./config --prefix=../sslout --openssldir=../sslout/openssl
	make
	make test
	make install
	cd ..

4. Generate public/private key pair
	cd telex-tag-v3
	make
	./genkeys
	cp pubkey ../relay_station
	cd ..

3. Build slitheen proxy
	cd relay_station
	make

4. Run proxy
	./slitheen-proxy [interface to client] [interface to world]
