This topic comes up from time-to-time, but I haven't seen a satisfactory answer.
I need a way to encrypt the source code on the micro SD card so that the card is useless if someone pulls it out and tries to make off with my IP. Obviously, some type of encryption key would be required by the loader to decrypt flows.
Extra credit: Allow the encryption to be applied at the flow or node level.
Has any thought been given to such a feature? What are others doing?
