StegoTorus

Welcome to StegoTorus by SRI International (http://www.sri.com)

The StegoTorus website is: http://sri-csl.github.io/stegotorus

What is this?

Please see "StegoTorus: A Camouflage Proxy for the Tor Anonymity System" for a detailed explanation on what this tool does and how it does it. A copy can be found at https://github.com/SRI-CSL/Stegotorus/blob/master/doc/stegotorus.pdf?raw=true

General Compilation

A prerequisite is the installation of SRI's jpeg embedding library, jel, from (https://github.com/SRI-CSL/jel).

Prepare the raw git repository first and generate configure and Makefile:

autoreconf -i
./configure --enable-silent-rules

To compile manually:

make

Debian

To make a Debian package:

make deb

This will likely ask for various packages to be installed that are needed for compilation.

Mac OS X

Install homebrew (if you do not have it yet):

ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

Install dependencies:

brew install autoconf automake cmake docbook jansson libevent libtool openssl pkg-config readline tor

Compile StegoTorus:

cd stegotorus
autoreconf -i
./configure --enable-silent-rules libcrypto_CFLAGS=-I/usr/local/opt/openssl/include libcrypto_LIBS="-L/usr/local/opt/openssl/lib/ -lssl -lcrypto" libz_CFLAGS=-I/usr/include/ libz_LIBS="-L/usr/lib -lz" libjansson_CFLAGS=-I/usr/local/opt/jansson/include CFLAGS=-Wno-format-nonliteral
make

Note that on OS X 10.9 libz is new enough, hence why we point it there, we disable -Wno-format-nonliteral as we have code that does this, might want to properly solve this by adding the relevant pragmas that indicate that these strings need format checking though.

Windows

Cross-compilation happens from a Debian/Ubuntu host.

Just run:

./cross-compile

and all should get arranged. This fetches and uses MXE for cross-compilation.
