Question

How do I hash the admin password in my Users table?

Using SQL Server 2008 R2

I know there is an encryption command is built into PHP but I’m not sure if this is possible using an SQL query.

Example: Table called users, with entry of admin, password is sha1('password')

Answer 1

Use HASHBYTES and specify SHA1 as the algorithm. Example:

SELECT HASHBYTES('SHA1', @password);

Edit: as Siva said in the comments though, you should really be storing your passwords differently and at least salting them.
