Аннотация

It has been several thousand years since mankind began to understand and speak to each other. It's no secret that ancient Egypt, Mesopotamia, and the Greeks used different writing and symbols in their civilization. Not everyone could read them. Centuries later, it became possible to read the inscriptions that keep the civilization inside. It became possible to read Euroglyph, cuneiform writing. Despite this, among the finds, several documents were found, the writing of which is incomprehensible or child's play. They were from encryption. Today, it is natural that codes, hidden symbols, all these things become commonplace. Sometimes children use different symbols or their own way of speaking to remind their friends. Some of its types are complex. But it is very strange for what purpose they were used in the period of early civilizations. Isn't writing enough to understand each other? Encryption is the encoding of data to ensure its security, as well as information that can be understood by a group of people. Long before the advent of digital technology, encryption emerged as a way to protect messages from prying eyes. Early examples of it were also used for decoration, and for writing down trade secrets that chefs or craftsmen did not want to share with others in their profession.
