This disclosure describes a method to protect diagnostic files against being read by unauthorized parties.
Using this method, a public key can be stored on the device and used to encrypt diagnostic files, which
can then only be read using the corresponding private key. This approach could be extended to protect
any files generated by a device during transit to an authorized party.
