Subject: Re: How to limit the number of guesses?
Basically, I would like to stop the session when a # number of guess is
reached, where a guess consists in testing a single candidate string,
regardless of being mangled (using rules); that is, mangled guesses would
count towards the limit.
In my experiment, I have a custom program generating guesses that are piped
to JtR (--stdin mode).
Let's say I want to know how many hits I get after the first 1,000,000
guesses in two conditions:
1) using my custom guess generator
2) using JtR with a default wordlist
Thanks,
