Router Configuration Question

I have a quick question. Does any one know the purpose of the private-config and underlying-config on cisco routers?

Re: Router Configuration Question

The file named startup-config is the current startup configuration file, in physical NVRAM or in Flash memory. If the file is located in a Flash memory file system, this entry is a symbolic link to the actual file. The file named underlying-config is always the NVRAM version of the configuration.

The private config contains data that can never be displayed.

Presumably, these are keys and certificates used by crypto image.
