Explanation:
In most situations, if an attacker sniffs your password from the network wire, she still has some work to do before she actually knows your password value. This isbecause most systems hash the password with a hashing algorithm, commonly MD4 or MD5, to ensure that passwords are not sent in cleartext. The operating systemencrypts the password into a hashed value, not the Syskey utility. a Windowsenvironment the passwords are stored in a Security Accounts Management (SAM) database in their hashed version. For extra protection, administrators can use a Syskey utility that encrypts the database that stores the passwords with a locally stored system key.
