I know how to export/import key containers in IIS using the aspnet_regiis command. Using that, I can export e.g. iisConfigurationKey that is used in applicationHost.config for the AesProvider and import the key container on another server.
But what I don't understand is how the sessionKey attribute on e.g. AesProvider fits into this. It looks nothing like the contents of an exported key container XML (it's not similar to the private nor the public key).
How is the sessionKey attribute generated (in correlation with the key container) and what is its purpose?
