Бит - это минимальная единица измерения информации.
В 16-ричном коде это выглядит так:
C1 E8 F2 20 2D 20 FD F2 EE 20 EC E8 ED E8 EC E0
EB FC ED E0 FF 20 E5 E4 E8 ED E8 F6 E0 20 E8 E7
EC E5 F0 E5 ED E8 FF 20 E8 ED F4 EE F0 EC E0 F6
E8 E8 2E
Если применить к каждому байту функцию XOR 55 (исключающее или с числом 55),
то получится
94 BD A7 75 78 75 A8 A7 BB 75 B9 BD B8 BD B9 B5
BE A9 B8 B5 AA 75 B0 B1 BD B8 BD A3 B5 75 BD B2
B9 B0 A5 B0 B8 BD AA 75 BD B8 A1 BB A5 B9 B5 A3
BD BD 7B
Самое интересное в этом коде то, что применив к нему снова XOR 55, мы получим исходное сообщение.
