Every char you add multiplies that time by 62 or so depending on the valid char spec. 52 for upper and lowercase plus 0-9= 62. Add 13 more if you allow the punctuation on the upper row of keys shifted, I ran into a supplier site still useing 8 chars last summer, and sent them a 'gram about it, fussing that I won't do business with such a poorly protected site. I got an email from them the next Tuesday proclaiming their network guy had expanded the passwd length to 127 chars. I like 20+ chars personally as that would take John about the rest of the time for the universe to run down to find. But there are better tools for the specialists at hacking than John.
