If the sender and receiver have different keys then the message will still not be able to be decrypted by the
receiver. This also results in the receiver rejecting the incoming messages:
Message encrypted Message rejectedEncrypted data
Server ControllerLAN
Every time encryption is enabled at the server, it generates a new encryption key:
 Each controller will have a unique key, independent from all other controllers
 If encryption for a controller is disabled, then enabled again, the key is changed
 If encryption for a controller is disabled at the server, the controller must be defaulted
It is not possible to re-enable encryption without first defaulting the controller
If encryption is disabled at both the sender and receiver then messages received will be accepted.

The downside of this scenario is that anyone 'listening' between the sender and receiver can also receive the
messages.
