![]() LM hash breaks the password into two 7-character fields which are then hashed separately, allowing each half to be attacked separately. ![]() One example is the LM hash that Microsoft Windows uses by default to store user passwords that are less than 15 characters in length. If a system uses a reversible function to obscure stored passwords, exploiting that weakness can recover even 'well-chosen' passwords. Most passwords can be cracked by using following techniques :ฤก) Hashing :- 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. A common approach is to repeatedly try guesses for the password. Password cracking is the process of recovering secret passwords from data that has been stored in or transmitted by a computer system.
