Adds an External Key protector for startup. Required if the computer does not have a supported TPM and one has not already been added. To use a startup key, the saved external key file must be located on the root directory of a USB flash drive. Since both the -RecoveryKey and -StartupKey parameters produce External Key protectors, the saved files can be used interchangeably.
