I'm in the final stages of preparing a dissector for the Tor protocol. I think
I'm at the stage where I need a code review to get any further with it. I'm
also at the stage where I need to know if a Tor dissector is something the
Wireshark project is interested in!

Further information about Tor: http://www.torproject.org

Tor protocol specifications:

 * https://svn.torproject.org/svn/tor/trunk/doc/spec/tor-spec.txt
 * https://svn.torproject.org/svn/tor/trunk/doc/spec/rend-spec.txt

Updates to the patch are available at:

http://roberthogan.net/stuff/dissector/patches/

Instructions for applying and using the patch are available at:

http://roberthogan.net/stuff/dissector/tordissector-README.txt

Some notes on the Tor dissector:

 * It currently requires a patch to Tor. This patch is available at:
    http://roberthogan.net/stuff/dissector/patches/tor-dissector.diff
   The Tor devs have agreed in principle to apply the patch (or a version
   of it) after their current change freeze.
 * To decrypt Tor's TLS traffic I had to modify packet-ssl-utils.c
   and packet-ssl.c to accept TLS Master Keys for decrypting TLS
   traffic.
 * Libgcrypt does not currently support AES-CTR mode for blocks of text
   that are not a multiple of the cipher's block size. For this reason,
   packet-tor.c contains a wrapper function to implement CTR mode. The
   libgcrypt maintainer intends to address this issue in the next version
   of libgcrypt.
