* Call FileReadStr() and pass the key file name and the key array as parameters. This will read the key
* from the file.
* Call ModelSetKey() to store the key that was read from the file.
* Call ModelGetMode() to get the mode from the Model (the mode was parsed from the command line).
* Call ControllerEncryptDecrypt() and pass the mode and msgOut as parameters.
