This post kind of inspired me to whip this up (probably not original, but it's minimal): https://bitbucket.org/logannc/deterministichashpass

Basically the same idea but seeds a random number generator with the master password and the service name to have an infinite supply of passwords. Technically no state is needed because Python's random module is deterministic, but I will end up saving the state with the service name and the index of the random number so that I don't have to try each and every one (not that I change passwords that often, for better or worse).

And, for convenience, since I won't be saving the master password, I'm looking into adding a credential cache like sudo has.
