Cryptanalysis is a scientific and practical activity of investigating cryptographic algorithms to obtain reasonable estimates of their cryptographic strength. An algorithm is considered cryptographically strong if the method of cryptanalysis, based on full key search, is ineffective for it, and no other faster methods of its cryptanalysis exist (or are not known). Any more efficient method of cryptanalysis reduces the theoretical evaluation of the cipher and is an option to “break” it. But it may well remain unrealizable from a practical point of view, and this is, as they say, details for specialists. That is why cryptographers remain calm and do not react to most urgent news about breaking this or that cipher, about access of special services to correspondence in social networks or about appearance of a new quantum computer – they know the details.
