Neural networks are a great tool for specific cryptography. On the transmitting side, a neural network is used (for example, on a computer or smartphone) to compose such text in which only certain bytes (characters) will be significant. For example, this would be an ad for a bulletin board. Even if the system cannot accurately select the words so that all characters occupy the right places in the text, the neural network will be able to restore the correct original text. It's just that extra characters that occupy the right positions in the text will be discarded when checking the syntax. Moreover, the text itself can already be encrypted.
