encrypting appSettings in a external file using aspnet_regii

We do this all the time as we use external files for each of our environments.

First your appSettings element needs to look like this:

 configSource="IndividualAppSettings.config" />

Next, we call the encryption from the cmdline using:

aspnet_regiis -pe "appSettings" -prov "{0}" -site {1} -app "/"

where:

• {0} is the name of your encryption provider specified in the web.config.
• {1} is the Id of your site in IIS
