" ??? It means that I've added a new function named split() to your code in revision 5.1 - please download it and see for yourself. I am assuming that you will integrate this in your revision 6. To test for the problem with your revision 5 and see how it is resolved in 5.1, please use pw-lm-ntlm-mixedcase.gz (a file that I've provided to you privately). The problem is described here: http://www.openwall.com/lists/john-users/2007/03/07/7 http://www.openwall.com/lists/john-users/2005/12/17/2 Also relevant is this comment on split() in src/formats.h: * For hex-encoded hashes which are compared by the target system/application * irrespective of the case of characters (upper/lower/mixed) used in their * encoding, split() must unify the case (e.g., convert to all-lowercase) * and FMT_SPLIT_UNIFIES_CASE must be set. */ Oh, I forgot to add FMT_SPLIT_UNIFIES_CASE - please add it and test with pw-lm-ntlm-mixedcase.gz again. This should only affect the --show option, which I neglected to test with pw-lm-ntlm-mixedcase.gz for revision 5.1.
