A common approach ( brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [ 2]
John the Ripper. John the Ripper is a free password cracking software tool.

Rainbow table. A rainbow table is a precomputed table for caching the outputs of a cryptographic hash function, usually for cracking password hashes. Passwords are typically stored not in plain text form, but as hash values. If such a database of hashed passwords falls into the hands of attackers, they can use a precomputed rainbow table to ...
