I have just hacked together a KISS-style password generator named Tahin. It is based on the password creation concept suggested by e.g. Prof. Dr. Eike Kiltz.

The idea is that there exists a secure master password and a service-specific ‘identifier’. These two strings get concatenated, then you transform the concatenated string with a secure hashing function and base64-encode the result.

Update: I have just released Tahin 0.1.0.
