Part II. How to Deploy Password Attack Settings?

After attack type selected, you then need to set up attack settings accordingly. For each attack, the settings or sets are different, seen as below:

• Option 1: If you choose Brute-force Attack, the program will try all possible combinations by default, so no need to define any setting.
• Option 2: If you choose Brute-force with Mask Attack, you then need to click "Brute-force" on the taskbar. 

  Later you should define the sets such as Min Length, Max Length, Character Set etc. by yourself according to the possible clues about the password you could recall of.



• Option 3: If you choose Dictionary Attack, then click "Dictionary" on the taskbar.

  This attack is highly recommended. If use properly, it is the fastest when compared with the above two attacks. This attack is intended to seek the possible password based on a dictionary. 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. If so, the seeking scope is largely reduced and it is bound to save time for the process.
