WinPassword (formerly known as NT Password) is an application for NT / 2000 / XP / 2003 system administrators for finding breaches in system security. It tries to recover plain-text passwords analyzing user password hashes. If it is possible to recover a password within reasonable time, the password should be considered insecure. WinPassword also can 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 NT security model. WinPassword uses both traditional recovery methods (Brute Force Attack, Dictionary Search) and the Smart Table Recovery (TM) technique (based on "Rainbow Tables"), allows recovering long and complex passwords quickly: 7 characters password (all characters) can be recovered in 40 minutes (using Brute Force Attack the password can be recovered in 29 days).
