Trying to match a corporate policy? That's probably not a good idea. My suggestion is that you use more wordlists with more rules. Try all.lst from: http://download.openwall.net/pub/wordlists/ Try leaked password lists from: http://www.skullsecurity.org/wiki/index.php/Passwords http://dazzlepod.com/disclosure/ http://contest-2010.korelogic.com/wordlists.html For a larger ruleset, try the --rules=single option. Also, try things such as --external=Keyboard, --external=Repeats (this one is almost instant), and --external=Subsets. To answer your question more directly, to have incremental mode try alpha-numeric strings longer than 8 characters, you have to modify params.h, rebuild John from source, generate a new .chr file, and use that. This will work for lengths up to 10: http://www.openwall.com/lists/john-users/2011/12/07/10 http://www.openwall.com/lists/john-users/2007/07/04/6 So you may then have one instance of John doing length 9 and another doing length 10. For other cracking modes, the above is not needed. Alexander
