I would have though all.chr would contain only the 95 printable characters and yet the file is > 250k! I mean since john can check the LM split simultaneously there would be (95-26)^7 possibilities as I see it, right? If you divide that by the c/s these LM's are identified fairly quickly (100s of hours). I must really be missing something here (no surprise)! These appear to be "binary" files so not sure how they are used but john can also create custom *.chr files for a *.pot file as you mentioned earlier. Could you provide some tutelage on this. Also, this brings up one more point. Some NT hashes might use ALT-characters. Is it possible to include such characters in *.chr files. I'm getting a handle on rules and configuring john, BUT the internals I can't seem to get my head around just yet. My apologies for the lack of depth on my part and I appreciate your patience.
