Subject: Re: Noob question: how to feed 10 alphanum char min&max
 incremental to aircrack when "MaxLen = 10 exceeds the compile-time limit of 8"

Never tried, and depending on the hash it would vary, but something fast
like NTLM would likely take weeks.Depending on how I generated the
CHR file, I'm not sure if there is a "tri-graph" that would help JtR guess the
more likely digits, but I have used it to find long char only passwords that
were 12 chars in a few days.I'll let this run (1-16) as long as I can and see
if I can get you a number for at least the NT hash on a 2.33Ghz. I've certainly
cracked passes over 8 with it plenty of times. All digit pass's are not that
common in my experience so I've never thought of having a rainbow table
for them, esp when JtR goes through 1-8 so quickly.
