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.

       Ophcrack can be used with command line using the options below, or can be run  as  a  pure
       graphical software.
