Hi all,
I need to hash (MD5) all the password in our Sql Server 2000 database. I can easily generate a C#/VB.NET program to convert (hash) all the passwords, but I was wondering (more for my education than for a real compelling need) if it was possible to calculate MD5 hash directly in T-SQL.
Thanks to anyone who will answer.

It is using this code, but it is not native to the language.

Thank you very much. I hoped to find a way to do it directly with SQL statements, but this is good too!

A:
In 2005 and later, you can call the HashBytes() function. In 2000, the closest thing is pwdencrypt/pwdcompare, though those functions have their own pitfalls (read the comments of the link).

Thank you very much for your kind reply. At the end I choose Daniel's answer because I was looking for MD5 hashing, but your one came really close and the suggestion about pwdencryt/pwdcompare made me learn something really interesting.

A:
No, there is no native TSQL command to generate MD5 hash's in SQL Server 2000.
In 2005 and above you can use the HashBytes function: http://msdn.microsoft.com/en-us/library/ms174415.aspx
