orchid_zxg · 發(fā)表于 2022-7-25 10:16

1、版本：ZTE_STB_Tools_V2.1.1_T02

2、機(jī)器碼：sq12780001290000002348000041F9DD62000000002383AF36D97EF0A37A8D773BEE529BD6760A1FE21679CF22F7DF40E258C5ABDA16C630E840E45CB6153F46D768AC720E257F977C7D2B517EE7E738A536E1C024153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E3A364F4619463EBF

3、去掉：sq，未知的12，密文長度78，未知的0001
290000002348000041F9DD62000000002383AF36D97EF0A37A8D773BEE529BD6760A1FE21679CF22F7DF40E258C5ABDA16C630E840E45CB6153F46D768AC720E257F977C7D2B517EE7E738A536E1C024153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E3A364F4619463EBF

4、3DES key 16bytes：290000002348000041F9DD6200000000
key為16bytes加0擴(kuò)充至24bytes
290000002348000041F9DD62000000000000000000000000

5、剩下的是密文：
2383AF36D97EF0A37A8D773BEE529BD6760A1FE21679CF22F7DF40E258C5ABDA16C630E840E45CB6153F46D768AC720E257F977C7D2B517EE7E738A536E1C024153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E3A364F4619463EBF

6、密文加密方式為3DES，ECB模式，PKCS7填充，3DES在線加密解密：
http://tool.chacuo.net/crypt3des/
解密失?。?br />
7、這些重復(fù)的字節(jié)是干嘛的？
153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E153F46D768AC720E

你算法做錯(cuò)了

jianjie20130628 · 發(fā)表于 2022-7-25 20:28

需要配合算法解密才能得到明文，你算法呢，光拆分可不行

謝謝了，還是不太懂。3DES在線加密解密，不能解密，不知道錯(cuò)在哪里，請賜教。

沒學(xué)過編程，這玩意怎么用？在哪里填KEY？哪里填密文？

jianjie20130628 · 發(fā)表于 2022-7-26 12:58

從開始你都出錯(cuò)了，隨機(jī)罵為明文，注冊碼為密文，你隨機(jī)碼切割都錯(cuò)了，通過密鑰算出滴密文不也是錯(cuò)滴嘛

第一步都算錯(cuò)了哦
