To reduce that is the goal. It's like coding a message when we used to send messages back and forth during the war in indigenous languages so they couldn't be read midstream. We do the same thing today. As a message is being sent through the wire, you try to keep it as decoded as possible, but once it gets to its destination, someone has a token or a key to unlock the information and understand what's there.
