我是基于客户端的汇编代码分析出加密的算法和密钥的。
看加密的算法更像是AES加密（随机-迭代异或），但是我用C#的AES库的是解密不出来的。这游戏的代码和库都太老了，可能目前编程语言所使用的库都已经无法兼容之前的AES算法了。

我在IDA尝试只找到了解密的部分(key部分是要动态调试?), 但是这也是上帝视角找出来的, 因为本身就知道了解密部分~~, 对调试这方面不太了解大佬能指点一下么 这是我的QQ413400524

这部分对应了此仓库的decrypt_block 函数部分，IDA可以查找交叉引用（点击函数让光标停留在函数处，按键盘X键），只要一直找引用，总有地方传密钥的

你的QQ应该是设置了什么，我这里无法搜到
