Can I use Encryptionizer to protect a database from the DBA?

In many cases, yes.  This is often important to developers distributing an MSSQL Server or SQL Express-based application. They want to ensure that the end user can only access the database through the supplied application, not through SQL Management Studio or a query window.  Just changing the SA password is not enough! The end user can easily foil this. For example, they can: copy the database to a fresh install of SQL Express or SQL Server; or restore the backup to a different instance of SQL Server; or even overwrite your Master database with one from a fresh install of SQL Server or SQL Express.  If your application uses a dedicated instance of SQL, it is possible to lockout Sysadmins from accessing encrypted data.
