NAME

       Ophcrack - a Microsoft Windows password cracker using rainbow tables.

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.
