MACRO (MAKR)-MATHEMATICAL REPLACEMENT MODULE. The replacement module does not affect the amount of information during encoding and decoding, but allows you to encrypt information in such a way that it cannot be recognized by directly comparing the encrypted and original messages without using a key. It can be used for encryption without a computer - for example, when you need to transfer information from a mobile phone in encrypted form. To use the replacement module, you need to understand the operation of the module, build and use permutation tables.
