JtR has a very useful incremental mode which generates password candidates in a sequence that more likely passwords will be cracked first. IMO, you can't compare PasswordPro's incremental mode with this strategy: http://www.insidepro.com/doc/003e.shtml That will take a long time to go until you reach the limit of length 32, but I doubt that AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA BAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA CAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA ... is a useful sequence to try, even if it *might* have advantages when compared to. AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAB AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAC ... Did you really crack a password longer than 8 characters using PasswordPro's incremental mode? But if you insist, you can easily implement an external mode for JtR which does this for you.
