Besides oral conversations and written language many other ways of information-transport are known: like the bush telegraph, drums, smoke signals etc. Those methods are not cryptography, still they need en- and decoding, which means that the history of language, the history of communication and the history of cryptography are closely connected to each other
The timeline gives an insight into the endless fight between enciphering and deciphering. The reasons for them can be found in public and private issues at the same time, though mostly connected to military maneuvers and/or political tasks.
One of the most important researchers on Cryptography through the centuries is

The result of this informatisation is the creation of a virtual body which is the exterior of a man or woman's social existence. It plays the same role that the physical body, except located in virtual space (it has no real location). The virtual body holds a certain emancipatory potential. It allows us to go to places and to do things which in the physical world would be impossible. It does not have the weight of the physical body, and is less conditioned by physical laws. It therefore allows one to create an identity of one's own, with much less restrictions than would apply in the physical world.
But this new freedom has a price. In the shadow of virtualisation, the data body has emerged. The data body is a virtual body which is composed of the files connected to an individual. As the
The virtual character of the data body means that social regulation that applies to the real body is absent. While there are limits to the manipulation and exploitation of the real body (even if these limits are not respected everywhere), there is little regulation concerning the manipulation and exploitation of the data body, although the manipulation of the data body is much easier to perform than that of the real body. The seizure of the data body from outside the concerned individual is often undetected as it has become part of the basic structure of an informatised society. But data bodies serve as raw material for the "New Economy". Both business and governments claim access to data bodies. Power can be exercised, and democratic decision-taking procedures bypassed by seizing data bodies. This totalitarian potential of the data body makes the data body a deeply problematic phenomenon that calls for an understanding of data as social construction rather than as something representative of an objective reality. How data bodies are generated, what happens to them and who has control over them is therefore a highly relevant political question.
