problem with encryption & decryption connectionStrings

I used the following command to encrypt my connection string but an error开发者_JS百科 ocurred

"The connection name 'DatabaseConnectionString1' was not found in the applications configuration or the connection string is empty"

How can I encrypt it while keeping the application working?

The command used was

aspnet_regiis -pef "connectionStrings" "C:\Users\ANAS\Documents\Visual Studio 2008\WebSites\WebSite7"

What if I move the encrypted application to another computer? Will it work?

You can't. If you change your web.config your application is initialized.

It will not work. You can only encrypt config sections on the same machine you decrypted it before. That's the reason why this is secure: You can't take a config file away and decrypt it on another machine.
