1) Normal

If you don’t know what the password is, select “Normal” It will try all possible combinations of keys within the specified range until the correct password is found. This is useful when you have a basic understanding of which characters the password consists of.

For example: If you know that a password consists of all small Latin letters and numbers, you can select only those two options and then deselect other characters. Since the software only needs to scan a limited number of characters, the decryption time will be greatly reduced.

2) Mask

The mask attack can be useful when you remember a portion of your password.

For example, if you know that your password has 8 characters and starts with ” isum” and it is difficult to remember the rest of the password combination, you can type ” isum ????” in the Mask box. The question mark symbol represents the unknown and the software will only search for missing characters.

Similarly, if you know that your password does not contain any specific symbols or uppercase letters, you can uncheck them. For this reason, the Length tab is disabled because you need to know the exact character length at which the mask attack works.
