    auto decrypted_data = BrainSeeDecrypt(g_encrypted_data, sizeof(g_encrypted_data));

此处的 sizeof(g_encrypted_data) 应为 len。

我的 demo 的定义是 unsigned char g_encrypted_data[6628]，因此计算 sizeof(g_encrypted_data) 得到的是 6628；你这里的类型是指针，得到的是 4。

此外你可以直接用 vector 来避免手动管理内存：

    std::vector<uint8_t> buffer_vec();
    ifstream fl("GUJUNYI_20200718.ban", ios::in | ios::binary); 
    fl.seekg( 0, ios::end );
    buffer_vec.resize(fl.tellg()); // 更改容器大小
    fl.seekg(0, ios::beg);  
    fl.read(reinterpret_cast<char*>(buffer_vec.data()), len);
    fl.close();

    std::cout << " GUJUNYI_20200718.ban read len: " << buffer_vec.size() << std::endl;

    auto decrypted_data = BrainSeeDecrypt(buffer_vec.data(), buffer_vec.size());
    std::ofstream ofs(L"dump.bin", std::ios::binary);
    ofs.write(reinterpret_cast<char*>(decrypted_data.data()), decrypted_data.size());
    ofs.close();

    std::cout << "写出了 " << decrypted_data.size() << " 字节到 'dump.bin'" << std::endl;

最好是把文件发出来一起看

unk* 的数据类型和大小都是未知，只有在运行的时候分析或根据操作这部分内存 ...

完整代码上传了，有点长，主要就是加注释那段不是太理解，主要是对指针偏移，初始化，赋值换来换去不太理解

void* 表示未知类型的指针。你可以改成 char* 凑合着用。
unk 开头直接双击查看，如果看不到内容表示这个地址不在 exe 内，可能是动态分配。用调试器附加或 cheat engine 之类的内存查看工具看这个地址的内存。
this 地址偏移你把它当普通的偏移看就行。this 是一个结构体指针（vtable）。
sub_427160 是 memcpy 的包装，前两个参数是指针。

sub_427160(this + 11, Src, 0x104u); 从 src 复制 0x104 字节到 this + 11 处
sub_427160(this + 76, a5, 0x2C4u); 从 a5 复制 0x2c4 字节到 this + 76 处

看起来像是有覆盖。

this 这个变量看起来更像是一个 char* 指针变量，而不是一个类的实例。

谢谢爱飞的猫用调试器附加或 cheat engine 之类的内存查看工具看这个地址的内存方法还没用过，我用动态调试断点后通过下面的脚本可以得到这个地址的byte数据，但是长度我是自己随意输入的，
有没有什么办法知道unk 数据的长度的数据类型？或转为字符串

[Python] 纯文本查看 复制代码

def getEncodeStr6(addr, len, fmt):
    print("addr = > %06X %d" % (addr, addr))
    out = ""
    outstr = ""
    pos = 0
    posSplit = 0
    while(True):
        ch = idaapi.get_byte(addr)
        if pos < len:
            #out += chr(ch)
            out += (fmt % ch)
            #out += ("%d " % ch)
            #print("%02x" % ch)
            outstr += chr(ch)
        else:
            break
        addr += 1
        pos += 1
        posSplit = pos%195
        if posSplit == 0:

sub_426E40 是一个 thiscall 方法中参数 _DWORD *this 调用时没传入，应该是编译器自动加上，我看有些文章说是指向函数，这个this在方法内使用 this + 11, this + 76 去做内存复制，
后续数据我应该如何获取？不知道如何和后续程序的指针对应上，这边有点不太理解，这个操作最后对应在操作哪个变量，是不是 memcpy 后的数据都在 v10 这个指针里面？
这样理解对吗？完整方法如下：

[C++] 纯文本查看 复制代码

_DWORD *__thiscall sub_426E40(_DWORD *this, int a2, int a3, void *Src, void *a5)
{
  sub_427160(this + 11, Src, 0x104u);
  sub_427160(this + 76, a5, 0x2C4u);
  *this = 1;
  sub_4269E0(this);
 // 这种 this[254] 和 this+245 是不是一样都是地址偏移意思？
  this[254] = 0;   
  this[257] = 0;
  this[255] = 0;
  this[258] = 0;
  *((_BYTE *)this + 1036) = 0;
  this[291] = 0;
  this[292] = 0;
  *((_BYTE *)this + 1172) = 0;
  *((_BYTE *)this + 1180) = 0;
  this[327] = 0;
  this[253] = a2;
  this[256] = a3;
  return this;
}

最好是把文件发出来一起看

unk* 的数据类型和大小都是未知，只有在运行的时候分析或根据操作这部分内存的代码进行分析总结。IDA 的自动分析也不是一定靠谱的，因为有时候编译器优化会干扰分析。

如果数据已知是字符串，你可以一直读下去直到遇到 00 字节的时候停止。（Unicode 字符串则是等到遇到 00 00 字节时停止）。

// 这种 this[254] 和 this+245 是不是一样都是地址偏移意思？
  this[254] = 0;
是也不是，this 的类型是 dword*，因此地址偏移是 this 指向的地址 + 254 × 4 （dword 是四字节）。

  sub_427160(this + 11, Src, 0x104u);
  sub_427160(this + 76, a5, 0x2C4u);

知道 this 是 dword* 后，（76-11）×4=260 字节，刚好是 0x104 的大小，第一个call参数的复制的字节数。

建议发原文件和调试步骤，单纯看伪代码能看出来的东西不多。

另外你可以试试 HexRaysCodeXplorer 插件，将 this + xxx 变成更容易阅读的结构体。

      //    其中 !this->buffer 就是 v12
      *((_DWORD *)this + 55) = operator new[](Length);
