1、版本：ZTE_STB_Tools_V2.1.1_T02
2、机器码：sq12780001290000002348000041F9DD62000000002383AF36D97EF0A37A8D773BEE529BD6760A1FE21679CF22F7DF40E258C5ABDA16C630E840E45CB6153F46D768AC720E257F977C7D2B517EE7E738A536E1C024153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E3A364F4619463EBF
3、去掉：sq，未知的12，密文长度78，未知的0001
290000002348000041F9DD62000000002383AF36D97EF0A37A8D773BEE529BD6760A1FE21679CF22F7DF40E258C5ABDA16C630E840E45CB6153F46D768AC720E257F977C7D2B517EE7E738A536E1C024153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E3A364F4619463EBF
4、3DES key 16bytes：290000002348000041F9DD6200000000
key为16bytes加0扩充至24bytes
290000002348000041F9DD62000000000000000000000000
5、剩下的是密文：
2383AF36D97EF0A37A8D773BEE529BD6760A1FE21679CF22F7DF40E258C5ABDA16C630E840E45CB6153F46D768AC720E257F977C7D2B517EE7E738A536E1C024153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E3A364F4619463EBF
6、密文加密方式为3DES，ECB模式，PKCS7填充，3DES在线加密解密：
http://tool.chacuo.net/crypt3des/
解密失败！
7、这些重复的字节是干嘛的？
153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E

1、版本：ZTE_STB_Tools_V2.1.1_T02
2、机器码：sq12780001290000002348000041F9DD62000000002383AF36D97E ...
你算法做错了
需要配合算法解密才能得到明文，你算法呢，光拆分可不行

谢谢了，还是不太懂。3DES在线加密解密，不能解密，不知道错在哪里，请赐教。

没学过编程，这玩意怎么用？在哪里填KEY？哪里填密文？
从开始你都出错了，随机骂为明文，注册码为密文，你随机码切割都错了，通过密钥算出滴密文不也是错滴嘛{znds10}
第一步都算错了哦
