850)     <br><br>
851)     <p>
852) Starting in 0.3.0.x, Tor supports a few fuzzing systems to check our
853) code for bugs.  But as of now, we only support a few possible entry
854) points to Tor.  It would be great to add fuzzing support for more of
855) our codebase -- ideally to include our whole network-facing interface.
856) That way, we could find more bugs in our code faster, and fix them
857) before they can get out of hand.
858)     </p>
859) 
860)     <p>
861) This won't be so easy, however: to fuzz effectively, we need to
862) refactor or mock the target function so that it doesn't change any
863) global state, or verify any signatures, or take too long to run.  With
864) lots of our network code, that's not so easy.  Make sure you
865) understand how our mocking system works, and what the challenges are,
866) before you apply for this one.

877) Tor relays spend a lot of time encrypting and decrypting relay
878) traffic, doing SHA1 and AES-CTR operations.  But right now, all of
879) this is done in the main thread!  It would be cool to split this
880) across multiple cores instead.
881)     </p>
882) 
883)     <p>
884) This won't be so easy though.  The code today is written to expect
885) immediate results from its encryption operations, so you would need to
886) do some pretty tricky refactoring in order get performance and
887) correctness here.  Make sure you understand how circuit crypto is
888) invoked today, and what the challenges are, before you apply for this
889) one.

942) Hidden services, hidden service clients, hidden service directories,
943) and introduction points all need to do a few public-key operations as

948)     <p>
949) This could probably be done in a way similar to how we currently hand
950) circuit extension handshakes in onion.c and cpuworker.c, but we'd need
951) to extend the state machine for hidden services to add an additional
952) state.  It could help hidden services operate much more efficiently.

1076)     <a href="https://stem.torproject.org/">Stem</a> is a Python library for working with tor. With it you can build applications on tor as well as learn information about the relay network. This project concerns this second capability.
1077)     </p>
1078) 
1079)     <p>
1080)     Information about relays are published hourly in documents called <a href="https://stem.torproject.org/tutorials/mirror_mirror_on_the_wall.html">descriptors</a>. With Stem you can download, parse, and validate all kinds of descriptor documents.
1081)     </p>
1082)

1084)     Ideas welcome! You're encouraged to brainstorm improvements we can make to this space but here's a few to get you started...
1085)     </p>
1086) 
1087)   <ul>
1088)     <li><p><b><a href="https://trac.torproject.org/projects/tor/ticket/11045">Validate signatures in the consensus</a></b>. Stem has the ability to validate cryptographic signatures in several descriptor types but not the consensus.</p></li>
1089)     <li><p><b><a href="https://trac.torproject.org/projects/tor/ticket/21086">Migrate from pycrypto to a supported library</a></b>. Stem presently uses pycrypto for signature validation but it's no longer maintained. We should evaluate options and move to whatever whavever the cool kids are using nowadays.</p></li>
1090)     <li><p><b><a href="https://trac.torproject.org/projects/tor/ticket/18856">Retrieve descriptors over tor's ORPort</a></b>. Tor relays commonly provide two ports, an <b>ORPort</b> which is used by clients and a <b>DirPort</b> which is obsolete nowadays but in the past was used by tor to download descriptors. Stem still uses tor's DirPort to retrieve descriptors, but it would be neat if we could download from the ORPort instead.</p>
1091)       <p>This requires implementing part of tor's communication protocol. Depending how complicated this is it might be neat to expand this task to allow the full construction of circuits, allowing client usage of tor without the C executable. Keep in mind though that this later bit hasn't been investigated and might be a pipe dream. ;P</p></li>
1092)     <li><p><b>Improve performance of reading descriptors</b>. Stem <a href="https://stem.torproject.org/tutorials/mirror_mirror_on_the_wall.html#are-there-any-other-parsing-libraries">isn't the only descriptor parsing library</a> and sadly is the slowest. Tricks like lazy loading have substantially improved our performance but no doubt a dedicated effort to profile Stem would find more low hanging fruit.</p></li>
