Currently, there are 8 decryption methods available:
- Preliminary attack usually runs before each attack.

- Brute-force attack guesses the password trying all possible password variants by given character set.
- Mask attack is very helpful if there's any information about the password.
- Base-word attack. Useful if a part (or source word) of the password is known.
- Combined dictionary attack uses to guess complex/compound passwords.
