Elcomsoft has a product that uses GPUs to do password-cracking on a
variety of media. They claim a speed-up of up to 67x, depending on the
application being attacked.

(This has led to a variety of stories (see, for example,
http://www.scmagazineuk.com/WiFi-is-no-longer-a-viable-secure-connection/article/119294/)
claiming that WPA is dead. The correct answer, though, is that
passwords are dead, especially bad ones.)
