Bruteforce

The Bruteforce method generates all possible combinations out of a charset and test it against the password protected file until there's a match. This methods can take everything from a few seconds up to days, weeks, months and even years depending on the complexity of the password. The longer the password and variations and mixture of chars and symbols, the harder it is to recover.

However, if you partly remember the password, you can speed up the recovery process significantly by defining a prefix and/or suffix. More info below.

1. Select "Charset" or define your own (option 9). If you define your own, type in all chars you want to be included in the Charset and press [ENTER].
2. Set Password Min-length. This defines the length of the password Kraken should start with. 1 is default.
3. Set Password Max-length. This defines the maximum length of the password. If nothing is specified, "Unlimited" will be set.
4. Set Password Prefix. Should the password start with a fixed string of chars? Press [ENTER] to skip.
5. Set Password Suffix. Should the password end with a fixed string of chars? Press [ENTER] to skip.
6. Select Bruteforce speed. Press [ENTER] to start Kraken.

Dictionary Method

A dictionary is a *.txt file containing pre-defined passwords that is being tested against the protected file until there's a match.
Where to find free dictionary files? Google is your friend ;)

Drop your dictionary *.txt file(s) into Kraken's "Dictionary" folder.

1. Select a dictionary.txt file. If there's only one dictionary in the "Dictionary" folder, it will be selected automatically.
2. Select "Recovery Speed".
3. Start Kraken

Recovery Speed

Kraken comes with 4 different speed options depending on how much of your systems resources you want Kraken to use. If you need to use your computer while Kraken is running, speeds up to mormal are recommended.

1. Crawl - very slow.
2. Slow
3. Normal
4. Fast - WARNING! Very high CPU usage!

Autosave progress & Continue

Kraken automatically saves your recovery progress every 1000 password so you wont loose time spent trying to recover your password protected files.

To continue from where you left off, start Kraken and select "Continue" from the main menu and Kraken will load your previous configuration. Select recovery speed and start.

Password Backup

When Kraken successfully recovers a password, it will automatically be saved to "Recovered Passwords.txt" and to your clipboard so you wont loose it again ;)

Extract Recovererd Files

After a successful RAR, Zip or 7-Zip recovery, Kraken asks if you want to extract the archive. Press Y to extract or [ENTER] to exit.

You'll find your extracted archive in a folder on your desktop with the same name as your recovered file.

Prefix and Suffix

If you know the password start with one or more chars, then use Prefix and Suffix to speed up the recovery process.

• Example 1:

  You know the password start with www. and end with .com but forgot what's in between. Then set www. as Prefix and .com as Suffix.
  Kraken will then only bruteforce what is between the Prefix and Suffix. Ex:

  www.[kraken bruteforce].com

• Example 2:

  You know the password starts with #123 but forgot the rest, then set #123 as Prefix.
  Kraken will then only bruteforce what comes after the Prefix. Ex:

  #123[kraken bruteforce]

• Example 3:

  You know the password ends with _ABC but forgot the rest, then set _ABC as Suffix.
  Kraken will then only bruteforce what comes before the Suffix. Ex:

  [kraken bruteforce]_ABC
