I see you using a scaler?
Isn't running a scaler a bit of an anticlimax compared to the low-level stuff you're doing here?
I always wondered how the password system did work. It can produce some fairly crazy stuff... did you take a look at it?
EDIT: looks like tummai has it pwned so I suppose that's no more a point.
Hm. What scaler you mean?
