http://ophcrack.sourceforge.net/

cool features -


Multithreading:
Bruteforce module:
Command-line version: Ophcrack core is now completely separated from the GUI. You can now use it the g33k way.
New GUI: The new GUI in C++ uses QT and we hope it will ease your experience with ophcrack.
Support of mulitple simultaneous tables: Select the tables you have and you want to use once for all and watch ophcrack decides which tables to use or not and what to load in order to increase the speed of cracking.
Support new Vista free tables: We computed new Vista tables based on a dictionary. Some variations are applied to the words of the dictionary before being added to the tables. It enables us to release a brand new Vista LiveCD.
Session auto-saving: If for some reason you have to interrupt the cracking, it is possible to reload the state in which ophcrack was when you stop by loading a session file. This session file is auto-saved every 30 seconds.

enjoy everyone
