前面一段时间用：
void DecodeShellCode(unsigned char * ShellCode, int LEN, unsigned char SEED)
{
for(int i=0;i<LEN;i++)
{
ShellCode[i] ^= SEED;
}
}
做一个XOR解密，没有问题
最近新加了一个函数调用
UINT API_RegDeleteKey(LPSTR lpBuffer,UINT uSize)
{
UINT result;
typedef UINT (WINAPI *lpAddFun)(LPSTR,UINT); //返回值,形参类型参考函数定义
HINSTANCE hDll=LoadLibrary("advapi32.dll"); //函数所在的DLL
lpAddFun addFun=(lpAddFun)GetProcAddress(hDll,"RegDeleteKeyA"); //函数名字
if (addFun != NULL)
{
addFun(lpBuffer,uSize); //调用函数
FreeLibrary(hDll); //释放句柄
}
return result;
}
调用RegDeleteKey
两者分开用，都可以编译，但是合在一个程序里面就不行了。老出错。请大家帮帮忙！

void DecodeShellCode(unsigned char * ShellCode, int LEN, unsigned char SEED)
{
for(int i=0;i<LEN;i++)
{
ShellCode[i] ^= SEED;
}
}
改为：
void DecodeShellCode(unsigned char * ShellCode, int LEN, unsigned char SEED)
{
int i;
for(i=0;i<LEN;i++)
{
ShellCode[i] ^= SEED;
}
}
