Данилка, я через час закончу, если что. 21.45 НР закончила гораздо раньше - чудеса! **Rijndael** - это симметричный алгоритм блочного шифрования с различной длинной блока и ключа. Для **AES** длина блока составляет 128 бит, а длина ключа может быть 128, 192 и 256 бит.Таким образом можно говорить о трех различных версиях: **AES-128**, **AES-192** и **AES-256**. Шифр основан на циклических операциях. У каждого цикла (раунда) есть свой 128-битный ключ и входными данными для него является результат предыдущего цикла (раунда). Ключ цикла (раунда) может быть вычислен заранее или сгенерирован «на лету» из входного ключа. Благодаря своей регулярной (циклической) структуре этот шифр можно эффективно реализовать аппаратно. Последовательность циклических операций расшифровывания отличается от операций шифрования, что часто приводит к различиям в логических цепях, отвечающих за эти операции. Производительность системы при шифровании и расшифровывании информации также отличаются, так как при обратной операции циклическая функция сложнее, чем при операции шифрования. []

//Rijndael is a symmetric algorithm of block encryption with different length of block and key. For the AES the block length is 128 bits and the key length may be 128,192 or 256 bits. So, we can speak about three different versions of this algorithm: AES-128, AES-192 and AES-256. The base of the cipher is cyclic operations. Every cycle ( or round) has its own 128-bit key and its input data is the result of + a previous cycle. The cycle key may be calculated previously beforehand or generated "on the fly" from the input key. Thanks to its regular structure this cipher can be efficiently applied in computers. The sequence of deciphering cycles differs from enciphering operations, that's why there are some differences in the logic circuits which are responsible for these operations. Capabillity of the system in encrypting is also different than from the one in decrypting, because in the inverse operation the logical function is more difficult. // //5 // //очень неплохо // //P.S.
