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.

The glamour of the data body economy clouds economic practices which are much less than glamorous. Through the seizure of the data body, practices that in the real political arena were common in the feudal age and in the early industrial age are being reconstructed. The data body economy digitally reconstructs exploitative practices such as slavery and wage labour. However, culturally the data body is still a very new phenomenon: mostly, people think if it does not hurt, it cannot be my body. Exploitation of data bodies is painless and fast. Nevertheless, this can be expected to change once the awareness of the political nature of the data body becomes more widespread. As more and more people routinely move in digitised environments, it is to be expected that more critical questions will be asked and claims to autonomy, at present restricted to some artistic and civil society groups trying to get heard amidst the deafening noise of the commercial ICT propaganda, will be articulated on a more general level.
The more problematic aspect of this development may be something else: the practices of the data body economy, themselves a reconstruction of old techniques of seizure, have begun to re-colonise real political space. Simon Davis, Director of the London-based privacy campaigners
The constant adaptation process required from the modern individual has anonymised and structuralized punishment, which now appears in the guise of error messages and the privatisation of risk.

Formerly (until 1972) Standard Oil Company, Exxon is one of the world's largest corporations in terms of sales, with investments and operations in petroleum and natural gas, coal, nuclear fuels, chemicals, and such ores as copper, lead, and zinc. It also operates pipelines and one of the world's largest fleets of tankers and other ships. Exxon engages in every phase of the petroleum industry from oil fields to service stations. It is headquartered in Irving, Texas, a suburb of Dallas.
