The algorithm being the code leads to encryption. When Alan Turing worked on his Turing Machine, he planned a machine where the instruction-code was part of its working, where the binary code was a fixed logic in dispute, in other words the machine turning into its own algorithm, which means nothing else than dialectic.
And exactly here the theoretical work on cryptography touches - as a consequence of the actor always having been part of the technical arrangements - an issue of modern democracy, the question about the private and the public: the terms are changing, do not fit to their original meanings anymore. One might say the Internet is something private. One might state the contrary. Both sentences are wrong. It is neither of them. Maybe we do not all feel it yet, but humans are going through a stage of blurred words, where classic definitions get lost, just like the codes/algorithms of behavior. The meta-narratives break down, not leaving anything but puzzle pieces. We can never be private on the Internet. Nor could we be in public if we were "out there" in virtual reality.
Cryptography, the study pretending to work for privacy, cannot provide us with absolute privacy either, as the danger of losing it through a decryption attack hinders its prospering. At the latest with the quantum computers coming into existence the patterns of the encoded picture will not be visible anymore. At the same time the social relations, its exact and excluding meanings must blur.
Democracy needs something to rely on, something to refer to, just like the private and the public.
Still, our need for privacy on the one hand and curiosity on the other hand create the longing for cryptography of information as well as its decoding.
"Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world."

"The multiple human needs and desires that demand privacy
among two or more people in the midst of social life must
inevitably lead to cryptology wherever men thrive
and wherever they write."
David Kahn, The Codebreakers
In the age of the vitreous man, whose data are not only collected by different institutions but kept under disclosure, out of reach, uncontrollable and unmanageable for the individual, privacy obtains new importance, receives a much higher value again.
The irony behind is that those who long for cryptography in order to preserve more privacy actually have to trust the same people who first created the methods to "produce" something like that vitreous man; of course not the same individual but persons of the same area of science. It is the reign of experts.
So far about self-determination.
