Data file integrity and security
The micro-update files containing data are compressed and encrypted. Data that
is not encrypted with the correct key will be ignored. As a result, DNS or IP
spoofing is not a concern. The contents of the data files are read into memory at
startup, as well as each time a new file is downloaded.
