WinPassword (formerly known as NT Password) is an application for NT/2000/XP/2003 system administrators for finding breaches in system security. WinPassword tries to recover plain-text passwords analyzing user password hashes. If it is possible to decrypt a password within reasonable time, the password should be considered insecure. WinPassword can also be used to recover lost passwords of particular users. Please note that this program is for advanced users and system administrators with good understanding of the Windows security model. WinPassword uses both traditional recovery methods (Brute Force Attack, Dictionary Search) and the new Smart Table Recovery (TM) technique. Smart Table Recovery (TM) technique is based on special precomputed recovery tables (rainbow tables) and it's especially useful for breaking complex 7 character passwords containing punctuation marks and other non-alphanumeric characters.
