In the meantime I found another thing that I'd like to ask about. You wrote about letter "M" that john didn't check if it's lower or upper-case. So when it will finish looking for the first 7 chars of my password will their case be unknown as well? [..] >The FAQ has this entry: > [..] > > >Did this answer your question? Yes.
