Abstract
In this paper we consider some of the problems, associated with the creation of the own cryptosystems as well as with the improvement of the existing ones. On an example of possible attacks on block ciphers we show that it is desirable not to create own block ciphers, but to use existing libraries. When considering the major attacks on MAC we show that it is possible to hack standard cryptosystems, tested by a lot of experts, and of course it is possible to hack the own ones. On an example of the error that was made by Apple in iOS we show that even minimal errors in the algorithm lead to the possibility of serious attacks. On the example of RSA we show that attempts to improve the work of standard cryptosystems are also connected with big difficulties. On the basis of these data we make a conclusion, that the creation of the new cryptosystems, as well as the improvement of existing ones, require serious expert review. It is noted that despite of a higher degree of the new hybrid cryptosystems safety, most of these systems are vulnerable to the attack "man in the middle".
