Hi all, I was wondering if is at all possible to discover a password one char at a time. Normally, you either get the password right or wrong (all or nothing).
Usually is not possible to infer any information on the right password just knowing that the tested one is wrong. A remarkable exception are cash card PINs: http://www.cl.cam.ac.uk/TechReports/UCAM-CL-TR-560.pdf -- IppatsuMan
