− | Packets sent/received with syscon 0xD2 are encrypted with the session key and IV = 0. There is a 4 byte command field, 4 byte counter (from keyslot 0x512) that increments per send, 6 bytes of zeros, and a 2 byte checksum. The checksum is the sum of all previous bytes and then negated. | + | Packets sent/received with syscon 0xD2 are encrypted with the session key and IV = 0.
