现在已经知道key A，keyb最后一字节的计算方式(以卡四为例，key B最后一位是98 8a 0d 2b 8b这样求和，得到的是E5），
UID 第四字节 XOR 09   是第1扇区2区块的第16字节
UID 第三字节 XOR 26   是第1扇区2区块的第15字节，

大家一起研究下，看看还有没有其他的规律

uid 前四字节 xor 31C89E75 = keyA 前四字节
uid 第二字节 xor 42 = keyA 第五字节

uid 前四字节 xor 31C89E75 = keyA 前四字节
uid 第二字节 xor 42 = keyA 第五字节

key A = (uid 前四字节 + 第二字节 + 第一字节）xor 31C89E7542A9。

好好研究。应该扔给ai 让ai给研究
