You are implementing an ASP.NET Web application that will connect to a Microsoft SQL Server database using predetermined credentials. You need to encrypt the Web.config configuration section that contains the connection string.

Which tool should you use?

ASP.NET IIS Registration Tool (Aspnet_regiis.exe) allows an administrator or installation program to easily update the script maps for an ASP.NET application to point to the ASP.NET ISAPI version associated with the tool. Executing with the "-pe" command line option encrypts the specified configuration section.

The ASP.NET Compilation tool (Aspnet_compiler.exe) enables you to compile an ASP.NET Web application, either in place or for deployment to a target location such as a production server. It does not support encryption of a configuration section.
