Everyone is saying that quantum computers are going to break RSA encryption. But what if they will never exist and the ones that "do exist" with too little power to do that don't exist at all and it's just propaganda to get people to ditch RSA?
Why? Two reasons.
RSA is maybe too strong and the government realized they let a useful tool out of pandora's box to allow people to keep secrets from them.
Second, some processes in Elliptic Curve cryptography (the alternative to RSA for asymetric cryptography) can support secret private keys. Just like RSA our private key is based on two other randomly selected numbers. But the "algorithm" it runs on depends also on two other parameters that often are suggested by the NSA or some other organization. So really the cryptographic system runs with 4 parameters, two of whom are selected by the NSA, but instead of calling it a parameter we call it a separate algorithm. The problem is for some applications there is a way, if you know some difficult to know very large number, to break the encryption. And you can calculate the right elliptic curve parameters if you pick the large number first.
So perhaps, quantum computers will never exist, and they are just a form of propaganda to push more people to use NSA breakable encryption and force it as a standard. The forcing of a standard is key. Even if you have the insight to want to use something better, you have to communicate in the standards that allow you to talk to others. You can end up forced to use an NSA breakable encryption if the NSA can have an influence on what the standards are.
