Hashish

Password generation and management tool, by Hadrien G. "Neolander" and Louis G.

Hashish is a password manager that eases using a different password on each online or offline service which you subscribe to. It generates unique service passwords from service names and a master password, and may also securely store pre-existing passwords which you cannot change.

Installation instructions

Here are binary packages for Windows and Linux x64. Just unpack them in a place where they won't bother you, and on Linux make sure that you have the Qt libraries installed. For an optimal user experience, I also recommend that you set up an easily accessible shortcut (keystroke, quicklaunch button...) in order to quickly launch Hashish whenever you need a password.
