Pwdencrypt() Weakness

Uberbloke submitted From "The Register" The inner workings of the undocumented pwdencrypt() hash function in Microsoft SQL Server have been revealed in a paper by security researcher David Litchfield of Next Generation Security Software (NGSS). Sort of thing that we ought to know about, I suppose. Thanks! The article is really a scare piece. It's really only a problem if you're already a system administrator on SQL Server. The other issue is if you used pwdencrypt() to secure other data in SQL Server. Turns out it's not quite that secure.
