I support a variety of older and newer ASP.NET-based applications, all of which rely on a standard key container for credential encryption. I am migrating much of the setup/configuration support for these apps to Powershell to the extent possible; however, I have not found an equivalent for the import of an xml-based RSA key:

aspnet_regiis -pi "ContainerName" "c:\SomePath\SomeKeyFile.xml"

There seem to be Powershell equivalents for nearly everything, but I have been unable to find one to accomplish this task. Does one exist?
