It's the scam of the century. It's happening now. It's called encrypt your secrets with good cryptography, and we'll just steal your key. So statistics show that whoever has a key to keep for a long time is a profane.
Today we are all profane.
And for us, for the profane, there is gibberish, like security in cyberspace, which does not yet exist.
And then there's gibberish for those who look at things superficially.
Everyone has a choice.
The con is where one writes for the sake of writing and being a legendary and untalented writer on the forum.
And if there is a desire to think freely, to think, for the sake of interest and not just to write, then I will write the following for those.
The key is what opens the lock. If the lock is not changed for a long time, the key can be picked. Therefore, if the lock is not changed for a long time, the key should be as sophisticated as possible. If you change the lock sometimes, there will be less time to pick the key. And if the lock is changed very often, the complexity of the key will cease to matter and there will be no time to pick the key. And if you change it even more often... then you can refuse the pair lock-key at all, it is enough to change, to know the direction of opening of this door. For example, the door to yourself is "1", the door from yourself - "0". Imagine that we need to guess 256 openings and never make a mistake. We can only try once, there is no time for a second attempt. The gambler will say - you can try. The analyst will say - there is no point in trying, it is the same as guessing a key that is 256 bits long. It is not possible to guess, because this problem cannot be solved, even by a complete search, in polynomial time, not only with modern computing power, even those that can be predicted in the future. And in our example, there is no time at all, let us say conventionally, one second and only one attempt. These explanations are given to understand the level of complexity of the problem, and hence the reliability of encryption in such a concept.
