A command line option (or an additional [config.name] section in john.conf and a command line option to choose a particular config) would be nice. I would, however, be interested to know which rule cracked a password. (For algorithms with MAX_KEYS_PER_CRYPT > 1, sometimes the new rule/incremental mode entry gets logged before all the previously generated passwords have been tried, even if the old rule/incremental mode entry generated the right password.) >I'd like to see some way to increase the benchmarking time to >get more coherent/stable/exact figures. Another config option;) >Optimize regexp expansion order [a-z] according to some >general/usage statistics. This will be hard to do, since usage statistics depend at least on -language preferences -password rules You can optimize manually, e.g. by specifying [enftisala-z] instead of [a-z]. >- When there are psw. hashes cracked in session, does john skip cracking >them >immediatelly? Or is there a session reload needed? Additional question: is it possible to send a signal to other currently running john instances, to let them re-read john.pot? >- I use adhoc "wordlist" rules a lot, could there be some kind of this >functionality: -rules:wordlist_set_1 for selecting wordlist rules?? You are not the first one asking for such a feature, see http://permalink.gmane.org/gmane.comp.security.openwall.john.user/22 and http://permalink.gmane.org/gmane.comp.security.openwall.john.user/23 (I wasn't the first one, either) >Another good thing to do would be to re-feed the cracked >passwords with the single-mode rules. Some single-mode rules are invalid when applied to a password list. I would like to decide which ruleset to try for cracked passwords. You can easily do it manually/semi-automatically. Hopefully, additional features will not impact John's cracking speed. Regards, Frank
