Simple language, easy to maintain or make further modifications we choose AES cipher in the randomized counter mode with a key space effectively
limited to 24 bits. Specifically, the key has the following format (in hex): 80 00 … 00 XX XX XX , where X is
an arbitrary hex number. In other words, the first 13 bytes of the key are fixed to be zeroes
