As scientists are working hard on a quantum computer and also on quantum cryptography one can imagine that another revolution in the study of encryption has to be expected within the next years. By then today's hardware and software tools will look extraordinary dull. At the moment it is impossible to foresee the effects on cryptography and democratic developments by those means; the best and the worst can be expected at the same time. A certain ration of pessimism and prosecution mania are probably the right mixture of emotions about those tendencies, as the idea of big brother has come into existence long ago.
At the same time it will - in part - be a decision of the people to let science work against them or not. Acceleration of data-transmission calls for an acceleration of encryption-methods. And this again falls back on us, on an acceleration of daily life, blurring the private and the public for another time.
We live in an intersection, job and private life growing together. Cryptography cannot help us in that case. The privacy in our mind, the virtuality of all private and public lies in the field of democracy, or at least what is - by connection to the Human Rights - regarded as democracy.

The Clipper Chip is a cryptographic device proposed by the U.S. government that purportedly intended to protect private communications while at the same time permitting government agents to obtain the "keys" upon presentation of what has been vaguely characterized as "legal authorization." The "keys" are held by two government "escrow agents" and would enable the government to access the encrypted private communication. While Clipper would be used to encrypt voice transmissions, a similar chip known as Capstone
would be used to encrypt data. The underlying cryptographic algorithm, known as Skipjack, was developed by the National Security Agency (NSA).
Gutenberg's printing press, an innovative aggregation of inventions known for centuries before Gutenberg: the olive oil press, oil-based ink, block-print technology, and movable types, allowed the mass production of the movable type used to reproduce a page of text and increased the production rate enormously. During the Middle Ages monks took at least a year over making a handwriting copy of a book. Gutenberg printed about 300 sheets per day. Because parchment was too costly for mass production - often for the production of one copy of a medieval book a whole flock of sheep was used - it was substituted by cheap paper made from recycled clothing left over from the massive number of dead caused by the Great Plague.
Within forty-five years, in 1500, already ten million copies were available for a few hundred thousand literate. Because individuals could examine a range of opinions now, the printed Bible, especially after having been translated into German by Martin Luther, and increasing literacy added to the subversion of clerical authorities. The interest in books increased with the rise of vernacular, non-Latin literary texts, beginning with Dante's Divine Comedy, the first literary text written in Italian.
Among others, the improvement of the distribution and the production of books and increased literacy made the development of print mass media possible.
Michael Giesecke (Sinnenwandel Sprachwandel Kulturwandel. Studien zur Vorgeschichte der Informationsgesellschaft, Frankfurt am Main: Suhrkamp, 1992) has shown that due to a division of labor among authors, printers and typesetters Gutenberg's invention increasingly led to a standardization of - written and unwritten - language in form of orthography, grammar and signs. To communicate one's ideas became linked to the use of a kind of code, and reading became a kind of rite of passage, in every human's life an important step towards independency.
With the increasing linkage of knowledge to wide reading and learnedness, the history of knowledge becomes the history of readings, of readings dependent on chance and on circumstance.
