+In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. There are two types of attack: one is Brute-force attack and the other is Dictionary attack. A common approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password. A dictionary attack is defeating a cipher by trying to determine its decryption key or passphrase by trying hundreds or sometimes millions of likely possibilities. It generates the hash from the dictionary entry and then compares them with the passwords.
