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.

       available.
