DESCRIPTION

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.
