Sys key technique

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 was an optional feature added in Windows NT 4.0 SP3. It was meant to protect against offline password cracking attacks so that the SAM database would still be secure even if someone had a copy of it. However, in December 1999, a security team from BindView found a security hole in SYSKEY which indicates that a certain form of cryptanalytic attack is possible offline. A brute force attack then appeared to be possible.
