Some places ban or at least think about banning encryption.
Encrypted traffic can be easily spotted because it looks like nonsense (or something else?).
Suppose I put my encrypted traffic into a jpg and add a message "Hey John, look at my newest fractals." Would it still look like encrypted traffic?
Of course, that trick works only until someone knows it. But there are a lot more sophisticated methods thinkable (make numbers into words, let it look like (nonsense) text for example).
Is this realistic or am I missing something important?
