<h2>Tor: Contribute</h2>

<p>People with sysadmin skills:
<ul>
<li>We need somebody to help out with our RPM spec file (there's an
in-progress version in the tarball).
<li>Can somebody set up a bugzilla for us, or other easy-to-use bug
tracking system?
<li>Can somebody take a look at Martin's <a
href="http://wiki.noreply.org/wiki/TheOnionRouter_2fSquidProxy">Squid
and Tor</a> page, and update it to reflect Tor's new <a href="">RedirectExit</a>
config option?
</ul>
</p>

<p>Developers:
<ul>
<li>We need somebody to code up a GUI or other
controller program, to do configuration, etc. See our <a
href="cvs/doc/control-spec.txt">control specification</a> for details,
and the <a href="cvs/contrib/tor-control.py">rudimentary python control
script</a>.
<li>We're always looking for better Windows installers.
<li>Does somebody want to do up a patch so we can be an NT service? Or
so we can go in the system tray?
</ul>
</p>

<p>Users:
<ul>
<li>Try Tor out, and let us know about bugs you find or features you
don't find.
<li>Please consider <a
href="http://www.freehaven.net/tor/doc/tor-doc.html#server">running a
server</a> to help us with development and scalability.
<li>Does somebody want to help maintain this website, or help with
documentation, or help with managing our TODO and handling bug reports?
<li>Please fix up <a
href="http://wiki.noreply.org/wiki/TheOnionRouter_2fTorFAQ">the FAQ</a>,
and if you know the answer to a question in the "unanswered FAQs" list,
please answer it.
</p>

<p>Graphics folks:
<ul>
<li>We need a Tor logo.
<li>We need a snazzy diagram or two, akin to the one BitTorrent has in
its <a href="http://bittorrent.com/introduction.html">introduction</a>,
to show people how Tor works.
</ul>
</p>

<p>People with money:
<ul>
<li>Go take a look at the <a href="http://www.eff.org/">Electronic
Frontier Foundation</a>.
</li>
</p>

<a href="mailto:tor-volunteer at freehaven.net">Let us know</a> if you want
to help out!

<h2>Tor: Design</h2>

<p>The <b>Design Document</b> (published at Usenix
Security 2004) gives our justifications and security analysis for the
Tor design:</p>
<ul>
<li><a href="tor-design.pdf">PDF version</a></li>
<li><a href="cvs/doc/design-paper/tor-design.html">HTML version</a></li>
</ul>

<p>The <b>Specification</b> aims to give
developers enough information to build a compatible version of Tor:</p>
<ul>
<li><a href="cvs/doc/tor-spec.txt">Main Tor specification</a></li>
<li><a href="cvs/doc/rend-spec.txt">Tor rendezvous specification</a></li>
<li><a href="cvs/doc/control-spec.txt">Tor UI control specification</a></li>
</ul>

<h2>Tor: Developers</h2>

<p>Read the <a href="cvs/doc/HACKING">Guide to Tor's source code</a> for an
overview of the various files and components of the system.</p>

<p>Check out <a
href="http://www.noreply.org/tor-running-routers/">weasel's graph of
the number of tor servers over time</a>. To learn more details of the
current Tor nodes, <a href="http://moria.seul.org:9031/">fetch the
latest dynamically generated directory</a>. (Your tor client fetches
this automatically, so loading it yourself is just for novelty.)
</p>

<p>Browse the Tor <b>CVS repository</b>: (which may not
necessarily work or even compile)</p>
<ul>
<li><a href="cvs/">Regularly updated cvs sandbox</a></li>
<li><a href="http://cvs.seul.org/cgi-bin/viewcvs.cgi/?cvsroot=tor">ViewCVS</a></li>
<li>anonymous pserver access (password is guest):
<ul>
<li>Make a new empty directory and cd into it.</li>
<li>cvs -d :pserver:guest at cvs.seul.org:/home/or/cvsroot login</li>
<li>cvs -d :pserver:guest at cvs.seul.org:/home/or/cvsroot co tor</li>
<li>(use -r tor-0_0_8 or equivalent to fetch a particular version.)</li>
</ul></li>
</ul>

<p>The <a href="">Java Anon Proxy (JAP)</a> project has implemented the
Tor client protocol in their client. More on that coming soon.

<h2>Tor: Packages and source</h2>

<p>You can get the <b>latest release</b> from the <a href="dist/">download
directory</a>. It should run on Linux, BSD, OS X, Win32, Solaris,
and more.<br>
<ul>
<li>Latest experimental: <a href="dist/tor-0.0.9pre5.tar.gz">0.0.9pre5</a>
(<a href="dist/tor-0.0.9pre5.tar.gz.asc">sig</a>)
<li>Latest stable: <a href="dist/tor-0.0.8.1.tar.gz">0.0.8.1</a>
(<a href="dist/tor-0.0.8.1.tar.gz.asc">sig</a>)
<li>Win32 executable (experimental, contributed):
<a href="dist/tor-009pre5.exe">0.0.9pre5</a> (<a
href="dist/tor-009pre5.exe.asc">sig</a>)  Be sure to read the <a
href="doc/tor-doc.html #installing">instructions</a> -- you'll need <a
href="http://www.slproweb.com/products/Win32OpenSSL.html">OpenSSL</a>,
and don't forget <a href="http://www.privoxy.org/">privoxy</a>)
</ul>
</p>

<p>See the <a href="developers.html">developers page</a> for instructions
on fetching Tor CVS. Old releases are <a href="dist/obsolete/">here</a>.
</p>

<p><b>Windows packages</b>:
<ul>
<li>Nick's contributed <a href="http://www.wangafu.net/~nickm/tor-0.0.9pre6-cvs-win32.exe">installer</a> for pre6-cvs.
<li><b>Outside link:</b> Aphex's contributed <a href="http://www.iamaphex.net/modules.php?op=modload&name=Downloads&file=index&req=getit&lid=66">Tor zip file for Win32</a> includes Tor, Openssl, Privoxy, SocksCap.
<li><b>Outside link:</b> Hideki Saito's contributed <a href="http://www.anime.net/~sasami/pub/tor/">tor setup exe</a> might work for you, especially if you speak Japanese.
</ul>
</p>

<p><b>Red Hat packages</b> are not available yet. We have a <a
href=cvs/tor.spec">spec file</a> but we're not sure if it's any
good. Please help.
</p>

<p><b>Debian packages</b> have been uploaded to unstable,
so you can just <code>apt-get install tor</code> if you are running sid.<br>

For stable (woody) or testing add these lines to your
<code>/etc/apt/sources.list</code> file:
<blockquote><code>deb     http://mirror.noreply.org/pub/tor stable main<br>
deb-src http://mirror.noreply.org/pub/tor stable main</code></blockquote>
and then run <code>apt-get update; apt-get install tor</code>.
Packages for architectures other than i386 can be added on <a
href="mailto:weasel at debian.org">demand</a>.
</p>

<p><b>Other packages</b> are available for Gentoo Linux, FreeBSD, NetBSD,
and OpenBSD. If somebody sends me details for these I'll put them here.

<h2>Tor: an anonymizing overlay network for TCP</h2>

<p>
Tor is a connection-based low-latency anonymous communication system that
protects TCP streams: web browsing, instant messaging, irc, ssh, etc. See
our <a href="overview.html">Tor overview</a> for more information.

<p>The or-announce mailing list is a low
volume list for announcements of new releases, etc. You can <a

<p>Remember that this is development code --
don't rely on the current Tor network if you really need strong anonymity.
</p>

<p>We've gotten a lot of press lately,
and so far the Tor network has stood up just fine to the flood of
new users. Great! To help make it scale even better, please consider <a

<h2>Tor: an anonymizing overlay network for TCP</h2>

<p>
Traffic analysis can be used to infer who is talking to whom over a
public network. For example, Internet packets have a header used for
routing, and a payload that carries the data. The header, which must be
visible to the network (and to observers of the network), reveals the
source and destination of the packet. Even if the header were obscured
in some way, the packet could still be tracked as it moves through the
network. Encrypting the payload is similarly ineffective, because the
routing information is all an observer needs.
</p>

<p>
Knowing the source and destination of your Internet traffic allows
somebody to track your behavior and interests, impacting your checkbook or
even threatening your job or physical safety.

Individuals, corporations, and governments all have an interest in
traffic analysis protection. Individuals want to protect themselves and
their family members from remote websites, or connect to resources such
as news sites or instant messaging services that are blocked locally.
User groups such as the German "Diabetes People" organization recommend
Tor for their members' online privacy and security.  Activist groups such
as the Electronic Frontier Foundation are publicizing Tor as a mechanism
for maintaining civil liberties online.  Corporations such as Google and
Wal-Mart are investigating Tor as a safe avenue for competitive analysis
or to try out new experimental projects without associating their name
with the project.  A branch of the U.S. Navy uses Tor for open source
intelligence gathering at its headquarters, and one of their teams used
Tor while deployed in the Middle East recently.
</p>

<p>
Tor helps to reduce the traffic analysis risk by distributing your
transactions over several places on the Internet, so no single point can
link you to your destination. To make private connections in Tor, users
incrementally build a path or <em>circuit</em> of encrypted connections
through servers on the network, extending it one step at a time so that
each server in the circuit only learns which server extended to it and
which server it has been asked to extend to.  The client negotiates a
separate set of encryption keys for each step along the circuit.
</p>

<p>
[Insert snazzy onion diagram here.]
</p>

<p>
Once a circuit has been established, the client software waits for
applications to request TCP connections, and directs these application
streams along the circuit.  Many streams can be multiplexed along a single
circuit, so applications don't need to wait for keys to be negotiated
every time they open a connection.  Because each server sees no
more than one end of the connection, a local eavesdropper or a compromised
server cannot use traffic analysis to link the connection's source and
destination.  The Tor client software rotates circuits periodically
to prevent long-term linkability between different actions by a
single user.
</p>

<!--
<p>
Many protocols, not just web.
</p>
-->

<p>
Tor also makes it possible for the clients to be hidden. Using Tor
"rendezvous points," other Tor clients can connect to these hidden
services, each without knowing the other's network identity. These hidden
websites let users publish material without worrying about censorship.
</p>

<p>
Of course, Tor can't solve all privacy problems itself. Tor focuses on
protecting the <em>transport</em>. You need to use other protocol-specific
software, such as Privoxy for web browsing, to clean identifying
information such as browser type and characteristics, and you need
to use other common sense such as not providing your name or other
revealing information in web forms. Also, like all anonymizing networks
that are fast enough for web browsing, Tor does not provide protection
against end-to-end timing attacks: if your attacker can watch the traffic
coming out of your computer, and also the traffic arriving at your chosen
destination, he can use simple statistics to discover that they are part
of the same circuit.
</p>

<p>
Providing a usable anonymizing network on the Internet today is hard,
both in terms of providing usable software that meets users' needs,
and also in terms of solving the research challenges. But we're making
progress at finding a good balance to provide both usability and security.
Our goal is to supplement laws by giving people the power to make their
own decisions about their privacy.

<h2>Tor: People</h2>

<p>Tor is managed by <a href="http://freehaven.net/">The Free
Haven Project</a> as one of the building blocks necessary for
a robust censorship-resistant data haven. It is developed by <a
href="http://freehaven.net/~arma/">Roger Dingledine</a> and <a
href="http://www.wangafu.net/~nickm/">Nick Mathewson</a>, with help from
many volunteers around the Internet.</p>

<p>Tor's first few years (2002-2004) were sponsored by the <a
href="http://www.nrl.navy.mil/">Naval Research Lab</a>, working with <a
href="http://www.syverson.org/">Paul Syverson</a> and based on the
original <a href="http://www.onion-router.net/">onion routing</a> idea
developed there.</p>

<p>As of November 2004, Tor is now sponsored by the <a
href="http://www.eff.org/">Electronic Frontier Foundation</a>. We are
EFF's first technology project.</p>
