a Microsoft Windows password cracker using rainbow tables.


ophcrack [options]


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 per‐ formance. 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.
