Encryption / Decrypting Web.Config

Hello,

I have a script below that will encrypt and decrypt my web.config file.
My question is if I have the web.config encrypted, how to I access the database name, username and password when I need to access the database?

Do I need to run the decrypt code everytime when I open up a database source?





code:
Public Sub Encrypt()
        Dim confg As Configuration = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath)
        Dim confgSect As ConfigurationSection = confg.GetSection(section)
        If confgSect IsNot Nothing Then
            confgSect.SectionInformation.ProtectSection(provider)
            confg.Save()
        End If
    End Sub

Public Sub Decrypt()
 Dim config As Configuration = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath)
        Dim confgSect As ConfigurationSection = config.GetSection(section)
        If confgSect.SectionInformation.IsProtected Then
            confgSect.SectionInformation.UnprotectSection()
            config.Save()
        End If
End Sub

Thanks
