Hi , so last months challenge went ok and i cracked most of my hashes 
..
Now lets assume i have a password hash that has 12 characters and i KNOW for a fact the last 2 characters are vb . Now, i also know that IN the password somewhere there is a "s" and a "m" or a "M" .. this would cut my password search down to 8 characters.. but because i dont know where those characters are, brings me up to 10 missing.. what would be the approach to reject all passwords from hashcat except the ones that contain an s and a m or M ? I dont want to do grep piping as is slows down... and reject rules ONLY work with left and right word lists? I mean there has to be a smarter way to do this?
