Password cracking is the process of recovering secret passwords from data that has been stored in or transmitted by ja computer system. A common approach is to repeatedly try guesses fro the password.
Most passwords can be cracked by usig following techniques:

1. Hashing Method:
Here we will refer to the one way function (which may be either an encryption function or cryptographic hash) employed as a hash and its output as a hashed password.If a system uses a reversible function to obscure stored passwords, exploiting that weakness can recover even 'well-chosen' passwords.
One example is the LM hash that Microsoft windows uses by default to store user passwords that are less than 15 characters in length.
LM hash breaks the password into two 7-character fields which are then hashed separately, allowing each half to be attacked separately.
