Nobody really knows for sure, but there is one thing you can be sure of, there are quantum computers out there right now as we speak. The ones that we definitely know of are D-wave systems quantum computers, which are commercially available and has several big name clients who have purchased a computer from them. There's really nothing to worry about as far as quantum computers go because they are an infant technology and are limited to specific functions on;y, but the real trouble starts when they gain more general function, that's when you arrive at the realization that the existing encryption is on it's way out the door, old news, good bye.
Really, i only knew that one from you. If that was reslly then it would be amazing somehow because we dont need to worry more. Base on my research most people really dont know if encryotion will last or not because no one controls it.
--------------------------
The existing encryption is not under anyone's control.
There is a general consensus, there is certification, there is advertising, it is enough for everyone to be vigilant.
This is used by large companies using their authority to produce products based on publicly available encryption libraries.
Small companies mistakenly think that what big companies have done is 100% correct and they do the same.
And so the whole world is connected by a chain of authoritative opinions, a pyramid from one "guru" to all ordinary pipels.
This is a system of general trust, on which the security for ordinary users is built.
Very few brave people who understand themselves, make their own conclusions, come to the essence, but make mistakes themselves.
It's good to be able to dig that deep.
And if you're not, if you don't even have time for it, what do you do?
I'm trying to find the answer to that question.
In my opinion, the only thing left to us who have not studied cryptography is to draw conclusions by getting indirect information, namely:
- why is there domestic cryptography and government cryptography?
- why in household cryptography the system of encryption at the level of algorithms is not updated, and in government cryptography it is obligatory?
- why are they so stubbornly searching for replacements for existing systems rather than just increasing the length of the key?
And here's another thing that can happen to those who believe in this general trust system:
- the Swiss government has filed a complaint in a criminal case against the CIA for using a Swiss supplier of encryption equipment to intercept communications from 120 governments over 50 years. The encryption products supplied by Crypto AG contained backdoors allowing the US and German intelligence agencies to easily read encrypted correspondence.
The security system, built on trust, which now exists in the world, seems to have collapsed completely.
Key-based encryption systems will never provide security for the average client, the average user, because it is the keys that will be stolen, this is the easiest way, because encryption algorithms are known and established as a constant.
