???? Encryption is not only a pleasure, but also a duty. After all, we encrypt communication with our bank, conversations with friends conducted via various messengers, or finally the content of our phones and computers. It is based on mathematics, often on prime numbers selected randomly. And it is this randomness, professionally called entropy, that is the most important element necessary for effective encryption of communication. Because if encryption is not random, then it may also be possible to predict, e.g. what prime number was selected as the basis of our cipher. And from there, it is only a step to putting it on its shoulders and quickly breaking it, resulting in the possibility of eavesdropping on everything we send. How to prevent this? Sources: ????
