I guess you're referring to this one? - # This silly example rule use the user-defined character class # example ?1 above. It will prepend any hex-string of at least # 4 digits within a candidate with 0x as well as with \x like # this: # 'hello' -> rejected # 'alibaba' -> 'ali0xbaba' and 'ali\xbaba' [List.Rules:Example] %4?1vap2Aa"[\\0]x" If so, that's not what I meant, although we should have removed it (feel free to submit a patch such that we don't forget). These examples are correct, right? - # This is a couple of example classes: # ?0 matches (one version of) base64 characters # ?1 matches hex digits # ?2 matches the TAB character (never try to use \x00!) [UserClasses] 0 = [a-zA-Z0-9/.] 1 = [0-9a-fA-F] 2 = \x09 Hmm, did you implement the \x09 thing? I am not sure. > Anyone having an idea of just what sample to make? I don't, at least not right now, sorry. > Anyway if someone on john-users complains about the results, it's the > rule's fault, not the class :) I think this confirms what I wrote above.
