Outside of professional carrier, I often stumble upon a need for a unique password for exp. for local database, game server, or on tons of, not so important, websites. I came up with an idea to write a deterministic password generator for myself, which takes a tuple: - master password - header for exp. just a word "pinterest" and generates a password of specified length, always the same I realise that this idea may not be the most secure and etc. But please focus on proper implementation, not the concept. The implementation: 1. Process master password and header using a password hash function like balloon hashing or argon2 (I believe that it adds some computational effort and makes it harder to obtain the master password from a few generated passwords) 2. Use the result of 1. as a seed for Fortuna DRNG to generate the password Are my assumptions about point 1. correct? Would you suggest some more operations? How should I process master password and header? Can I simply concatenate them and hash, or XOR their hashes, or compose?
