From Forced Entry Software:
Sesame allows you to load Windows Registry hives and discover Windows user-account passwords stored in those hives. Password discovery can take a long time - depending on the length of the password and the types of characters used, discovery by trying every combination (brute-force) can take days. Uniquely, sesame allows the user to inject a password of their own choice directly into the registry hive, thereby avoiding long discovery times. Version 1.9b may include unspecified updates, enhancements, or bug fixes.
