Abstract

This work is devoted to the study of methods and tools for evaluating the symmetric algorithms cryptostability. In particular, the question of protection against password attacks using the method of "brute-force". The mathematical model of password evaluation cryptostability and the idea of encryption with the auto-key is proposed. A combined algorithm for encrypting passwords with an auto key has been synthesized and its cryptographic stability has been determined
