This dictionary can be the integrated one or the one you provide. The integrated dictionary is a text file listing common character combinations, such as a, ab, 123, 4, AB, etc. that people may frequently use for passwords. You can also create a dictionary by listing your character sets that you frequently use to let the program base on when seeking passwords.
