typedef unsigned int uint32;
uint32 seed_temp_level1 = 0;

uint32 seedtemp2 = ~seed;
uint32 sum = 0, delta = 0x0ab16000;
k[0] = 0x4c495551;

for (int i = 0;i < 2;i++)
{
seedtemp1 += (((seedtemp2 << 4) ^ (seedtemp2 >> 5)) + seedtemp2) ^ (sum + k[sum & 3]);
sum += delta;

}
key = seedtemp1;
return key;
}
void main() {
for (int i = 0;i < 4;i++) scanf("%x", &seed[i]);
seed_temp_level1 = (seed[3]) + (seed[2] * 256) + (seed[1] * 65536) + (seed[0] * 16777216);
key_temp_level1 = OBDII_ComputeKey_Function1(seed_temp_level1);
key[0] = (key_temp_level1 >> 24) & 0xFF;
key[1] = (key_temp_level1 >> 16) & 0xFF;
key[2] = (key_temp_level1 >> 8) & 0xFF;
key[3] = (key_temp_level1) & 0xFF;
}
我的解答思路和尝试过的方法
格式已经用notepad刷过，还是有问题
