1 and 3?  I assume you mean 0 and 1, with 2 being unused anyway.  There should
really only be a 3, a straight hash or salted hash is barely better than just
using the password directly.

(They also seem to be virtually unused in practice, some time ago I
inadvertently disabled use of 0 and 1 in my code and, after zero complaints
over this, made the change permanent).
