This article reviews the problems of hacking and interception of data transmitted over telecommunications networks. The main approaches to data encryption are summarized. The principles of operation of simple asynchronous encryption algorithms AES and RSA are described. A step-by-step practical technique for implementing the above algorithms in a high-level cross-platform programming language Java is proposed, which is a solution to the problem of protecting data transmitted using modern communication tools based on the use of telecommunication technologies. According to the research results, recommendations on the cryptographic value of each algorithm are given, their advantages and disadvantages and examples of the preferred use of each option are described.
