What method is used for password cracking?
Brute force attack: In this method, the attacker repeatedly attempts to guess a password by systematically trying every possible character combination until a valid password is found. In this attack, the attacker uses a password-cracking tool that generates a list of possible passwords.
Where does John put cracked passwords?
Cracked passwords will be printed to the terminal and saved in the file called $JOHN/john. pot (in the documentation and in the configuration file for John, "$JOHN" refers to John's "home directory"; which directory it really is depends on how you installed John).

Since encryption is two-way, the data can be decrypted so it is readable again. Hashing, on the other hand, is one-way, meaning the plaintext is scrambled into a unique digest, through the use of a salt, that cannot be decrypted.

To add to what kichik said (all true): password hashing functions are intentionally slow to make the cost of brute force attacks computationally prohibitive. See wikipedia for more details. Don't use a random cost; use a cost that makes it slow enough to be secure.

Hydra works by using different approaches to perform brute-force attacks in order to guess the right username and password combination. Hydra is commonly used by penetration testers together with a set of programmes like crunch, cupp etc, which are used to generate wordlists.
Can you brute force any password?
With password salting, a random piece of data is added to the password before it runs through the hashing algorithm, making it unique and harder to crack. When using both hashing and salting, even if two users choose the same password, salting adds random characters to each password when the users enter them.
