HashPW for win/linux/mac
HashPW is the solution for getting strong unique passwords out of a master password and a public string. There is no need to carry around an encrypted container that stores your passwords like so called password-safe applications demand. Anytime you use your master password on the same string, the resulting unique password will always be the same.
Versions for Windows 98/XP/Vista, Linux and MacOS exist and can be downloaded via the menu on the left. The current Version is 2.0.0
