Just my opinion. > I've recently tried 15-20 characters from chr based on rockyou. Anything pver 11-12 characters (other than digit only) I can't find success with All.chr, however that's just me. At those lengths wordlists are the place to be, unless you can just let them run on and on, or you can really distribute it out, I'd say 15 is about all you can hope for max, pure alpha would stretch it, and I most work on fast hashes. But perhaps like you said, have Incremental: conf's contain the limitations and have chr files capable of more ship with JtR. I'd keep them at or below 15 in conf for sure. It is slower as well because john still iterates the more likely character sets, and having a length like that will have some new comers scratching their heads, I think. Adding in more possible characters I'm all for, but that too will as you pointed out slow things down naturally. If there were some filters (in conf) to go along with those CPxxxx (etc...) additions, I'm all for it. I won't need then often, but it'd be nice to know I can easily try them or create them, or an easily configured option to be just 0x32-0x7f? </my2cents> -rich Content of type "text/html" skipped
