Pyrit takes a step ahead in attacking WPA-PSK and WPA2-PSK, the protocol that today de-facto protects public WIFI-airspace. The project's goal is to estimate the real-world security provided by these protocols in a world of affordable Many-Core platforms.

Pyrit's implementation allows to create massive databases, pre-computing part of the WPA/WPA2-PSK authentication phase in a space-time-tradeoff. The performance gain for real-world-attacks is in the range of three orders of magnitude which urges for re-consideration of the protocol's security. Exploiting the computational power of Many-Core- and other platforms through ATI-Stream, Nvidia CUDA, OpenCL and VIA Padlock, it is currently by far the most powerful attack against one of the world's most used security-protocols. For more background see this article on the project's blog.

How to use

Pyrit compiles and runs fine on Linux and MacOS X. None of the BSD systems were tested but all posix systems should be fine anyway. I don't care about Windows; drop me a line (read: patch) if you make Pyrit work without copying half of GNU ...

How to participate

Contribution or comments are welcome under the project-owner's email address (look right). I also usually idle in #python and #cuda on irc.freenode.org
