Deterministic password generator with master password. (Please user a long master password) No Passwords are saved, so no cracker can find out your master password if he knows one of your (non-master) passwords. Generates another password for each website and is very handy to use.
Why? The generated password is a part of the SHA-256 hash of "[URI]+[MASTERPASSWORD]" so you cannot extract the master password. Use at your own risk...;)
