Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman's original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds.
Ophcrack works for Windows NT/2000/XP/Vista.
Ophcrack can be used with command line using the options below, or can be run as a pure graphical software.
If you have installed ophrack-cli package, graphical interface is not available.
ophcrack -g -d /path/to/tables -t xp_free_fast,0,3:vista_free -f in.txt
