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

New opportunities for online advertisers arise with the possibility of one-to-one Web applications. Software agents for example promise to "register, recognize and manage end-user profiles; create personalized communities on-line; deliver personalized content to end-users and serve highly targeted advertisements". The probably ultimate tool for advertisers. Although not yet widely used, companies like

Even with the best techniques it is impossible to invent a cryptographic system that is absolutely safe/unbreakable. To decipher a text means to go through many, sometimes nearly - but never really - endless attempts. For the computers of today it might take hundreds of years or even more to go through all possibilities of codes, but still, finally the code stays breakable. The much faster quantum computers will proof that one day.
Therefore the decision to elect a certain method of enciphering finally is a matter of trust.
For the average user of computers it is rather difficult to understand or even realize the dangers and/or the technological background of electronic transmission of data. For the majority thinking about one's own necessities for encryption first of all means to trust others, the specialists, to rely on the information they provide.
The websites explaining the problems behind (and also the articles and books concerning the topic) are written by experts of course as well, very often in their typical scientific language, merely understandable for laymen. The introductions and other superficial elements of those articles can be understood, whereas the real background appears as untouchable spheres of knowledge.
The fact that dangers are hard to see through and the need for security measures appears as something most people know from media reports, leads directly to the problem of an underdeveloped democracy in the field of cryptography. Obviously the connection between cryptography and democracy is rather invisible for many people. Those mentioned media reports often specialize in talking about the work computer hackers do (sometimes being presented as criminals, sometimes as heroes) and the danger to lose control over the money drawn away from one's bank account, if someone steals the credit card number or other important financial data. The term "security", surely connected to those issues, is a completely different one from the one that is connected to privacy.
It is especially the latter that touches the main elements of democracy.

Napoleon I. (1769-1821) was French King from 1804-1815.
He is regarded as the master of propaganda and disinformation of his time. Not only did he play his game with his own people but also with all European nations. And it worked as long as he managed to keep up his propaganda and the image of the winner.
Part of his already nearly commercial ads was that his name's "N" was painted everywhere.
Napoleon understood the fact that people believe what they want to believe - and he gave them images and stories to believe. He was extraordinary good in black propaganda.
Censorship was an element of his politics, accompanied by a tremendous amount of positive images about himself.
But his enemies - like the British - used him as a negative image, the reincarnation of the evil (a strategy still very popular in the Gulf-War and the Kosovo-War) (see
