Encrypting Web.config Connection Strings

<?xml version="1.0"?>

<!--
  Use this as a template for when you need to update the encrypted connection strings in
  `ConnectinStrings.config`

  To encrypt the `connectionStrings` section:

    1. Make a copy of this file and rename it to `Web.config` temporary.
       (`aspnet_regiis.exe` only succeeds if you name it that.)

    2. Open a command prompt in the current directory.

    3. Run `C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -pef "connectionStrings" "."`

    4. The `connectionStrings` section has now been encrypted in place.

    5. Rename the temporary `Web.config` file to `ConnectionStrings.config`

    6. In the newly created `ConnectionStrings.config`, make the `connectionStrings` section as the
       root element by removing `configuration` as the root element.

       You have to do this since `ConnectionStrings.config` is loaded into the application's root
       `Web.config` using `configSource`.

  To decrypt the `connectionStrings` section in place:

    1. Rename `ConnectionStrings` to `Web.config`
       (because `aspnet_regiis.exe` only succeeds if you name it that)

    2. Add a `<configuration>` tag and make it the root element enclosing `<connectionStrings>
       (again for `aspnet_regiis.exe`)

    3. Open a command prompt in the current directory.

    4. Run `C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -pdf "connectionStrings" "."`

    5. The connection strings are now unencrypted.
