Incremental Mode
read https://www.openwall.com/john/doc/MODES.shtml
This is the most powerful cracking mode, it can try all possible character combinations as passwords. However, it is assumed that cracking with this mode will never terminate because of the number of combinations being too large (actually, it will terminate if you set a low password length limit or make it use a small charset), and you'll have to interrupt it earlier.
