Steven the hacker realizes the network administrator of Acme Corporation is using syskey in Windows 2008 Server to protect his resources in the organization. Syskey independently encrypts the hashes so that physical access to the server, tapes, or ERDs is only first step to cracking the passwords. Steven must break through the encryption used by syskey before he can attempt to use brute force dictionary attacks on the hashes. Steven runs a program called "SysCracker" targeting the Windows 2008 Server machine in attempting to crack the hash used by Syskey. He needs to configure the encryption level before he can launch the attack. How many bits does Syskey use for encryption?
