问题描述
祝大家好日子！
我对这里的编码人员有一个简单的问题：
我有一个功能来加密/解密我的数据包使用已定义键的在线游戏.4
以下是随机生成的键：
Good day to you all!
I have a quick question for the pro-coders around here:
I have a function to encrypt/decrypt my packets in my online game using defined keys.4
Here are the keys, generated random:

这是函数：
here is the function:
typedef enum PROCESS_TYPE
{
ENCRYPT = 0,
DECRYPT = 1
};
inline void process_data(const PROCESS_TYPE type, const BYTE(*keys)[KEYS_NUMBER], BYTE * pData, const unsigned int uLen)
{
for (unsigned int i = 0; i < uLen; ++i)
{
pData[i] = keys[type][pData[i]];
}
}
所以我迷上了客户端网站send（），我正在尝试发送加密数据包像这样：
So i hooked on client site send() and i am trying to send encrypted packets like this:
process_data(ENCRYPT, client_keys, (BYTE *) buf, len);
在服务器端我连接了recv（），我试图像这样解密：
And on server side i hooked recv() and i am trying to decrypt like this:
process_data(DECRYPT, server_keys, (BYTE *) buf, size);
问题？好吧它总是给我套接字头错误...所以当试图解除数据包它不会工作...我不明白为什么，一些帮助请吗？
The problem? Well it always gives me socket header error... so when trying to DECRYPT the packet it wont work... i cannot understand why, some help please?
推荐答案
我认为问题似乎是你正在执行的操作顺序。
在你的评论中，你说成功的操作转变：
0xC1 0x06 0xA9 0x20 0x9C 0x2F
进入
0x81 0x6F 0x4E 0x07 0xB8 0x89
为了进行这种转换，我需要使用client_keys来解密 - 而你的问题让我觉得前6个byes是原始的，未修改的数据要传输。
然后是与使用client_keys的DECRYPT相反的是使用server_keys进行ENCRYPT，所以我尝试了。你猜怎么着？数据变为全圆并转换回原始序列，0xC1 0x06 0xA9 0x20 0x9C 0x2F
我尝试了所有4种组合，输入0xC1 0x06 0xA9 0x20 0x9C 0x2F
I think that the problem seems to be in the order of operations you're performing.
In your comment, you state that a successful operation transforms:
0xC1 0x06 0xA9 0x20 0x9C 0x2F
into
0x81 0x6F 0x4E 0x07 0xB8 0x89
In order to make this transformation, I needed to DECRYPT using the client_keys - whereas your question had given me the impression that the first 6 byes were the original, unmodified data to be transmitted.
It then follows that the opposite of DECRYPT using client_keys would be to ENCRYPT using server_keys, so I tried that. Guess what? The data's gone 'full-circle' and is transformed back into the original sequence,0xC1 0x06 0xA9 0x20 0x9C 0x2F
I tried all of the 4 combinations with an input of0xC1 0x06 0xA9 0x20 0x9C 0x2F
Method Output
---------------------------------------------
ENCRYPT client: 0x89 0x68 0x97 0x62 0x29 0x8B
ENCRYPT server: 0x67 0x51 0xB9 0xA5 0x31 0xAC
DECRYPT client: 0x81 0x6F 0x4E 0x07 0xB8 0x89 <--- Here's the expected output.
DECRYPT server: 0x1B 0x98 0x49 0xD1 0xC9 0xAE
唯一能够成功转换的是DECRYPT客户端。这让我更加沉重，相信你会在某种程度上变得困惑并在错误的时间应用错误的转换。
无论如何，这是一个简短的（可以！）片段，它会更改数据，然后再将其更改回来。希望能帮助到你。 :)
The only one that makes the successful transformation that you mention, was DECRYPT client. This lends yet more weight to my belief that you've become confused somehow and applied the wrong transformations at the wrong times.
Anyway, here's a short (as can be!) snippet that changes the data and then changes it back again. Hope it helps. :)
