Part 2: How does Dictionary File to Recover Password Work?

Dictionary attack (Dictionary File to Recover Password) tries thousands of words from dictionary files (also known as a word list) as possible passwords. While using Dictionary File to Recover Password, it allows you to customize the following settings:

Password length

The program searches for the password of the specified length.

Dictionary file

Passware Kit offers 9 built-in dictionaries: Arabic, Dutch, English, French, German, Italian, Portuguese, Russian, and Spanish. The program allows you to compile your own dictionary file by choosing the "Custom" option.


Define the part of the password. If any part of the password is known, enter it in the "Pattern" field. Known parts can be separated with '*' or '?'. For example, "*p?e*" will match both "apple" and "pie". All '?' characters in the pattern are replaced by exactly one letter. I.e. pattern "never?????" will match "neveragain" and will not match "forever", "nevermore". 

The '*' character is replaced by zero or more letters, i.e., pattern "never*" will match "never", "neveragain", "nevermore", etc.


Add Casing Modifier to the Dictionary attack to change casing of any or all letters of the password.

Reverse Password

You can add Reverse Password Modifier to the Dictionary attack to check for reversed words from the dictionary.

Dictionary File to Recover Password is usually quite fast. However, the password can be recovered only in case it is present in the dictionary, so where to find a good dictionary file.
