Microsoft SQL Server Passwords (Cracking the password hashes)
by David Litchfield - An NGSSoftware Insight Security Research Publication
SQL Server uses an undocumented function, pwdencrypt() to produce a hash of the user's password, which is stored in the sysxlogins table of the master database.

This paper will discuss the function in detail and show some weaknesses in the way SQL Server stores the password hash. In fact, as we shall see, later on I should be saying, 'password hashes'.
