(at least in John 1.7.8) 2) Behaviour: when hashes could be accepted by John in different formats (like mscash2 or md5_gen(n)) 'john -show' could show no results thinking about some hashes in one format while this hashes are already cracked as other format. So I propose to show format used by -show like at begin of cracking session. (1.7.8-j5; it seems to be actual with Jumbo or I do not know enough to reproduce it with formats supported by John without Jumbo) Widely I propose also to show hints for user about formats that potentially could be read from this file. (I am not sure that it is possible.) Regards, Aleksey Cherepanov
