A dictionary attack is an attack in which the attacker attempts to decrypt an encrypted message by comparing the encrypted value with previously computed encrypted values for the most likely keys. This attack is made much more difficult by the introduction of random bytes at the end of the password before the key derivation. These random bytes are known as salt.
