SysKey Utility to Prevent Windows Password Cracking

SYSKEY is a utility that encrypts the hashed password information in a SAM database in a Windows system using a 128-bit encryption key.

SysKey utility, also called the SAM lock tool, It can be helpful for preventing hackers from cracking Windows passwords

Description

Microsoft Windows Security Accounts Management Database (SAM) stores hashed copies of user passwords. This database is encrypted with a locally stored system key. To keep the SAM database secure, Windows requires that the password hashes are encrypted. Windows prevents the use of stored, unencrypted password hashes.
