For the purposes of this test, we use IUsernameHashedPassword, although this will never really be used by the command line. (I have, to date, not thought of a half-decent way for a user to specify a hash algorithm via the command-line. Nor do I think it's very useful.) I should note that, at first, this test is counter-intuitive, because we're using the checker with a pre-defined hash function as the 'bad' checker.
