Identify user who presses a certain key

Question

I have an online game, which players have an ID and a PASSWORD to enter, but there is a hack which can be turned on or off with the following keys (INSERT, DELETE and F1) I want to identify the users who press those keys , and save in a log.txt file the id of those users to know who they are.

What I have tried:

C++

#include <iostream>
#include <string.h>
#include <stdlib.h>
#include <fstream>
Using namespace std;
Int main()
{
ofstream archivo("userhack.txt", ios::out);

if(GetAsyncKeyState(VK_END)){

}
if(GetAsyncKeyState(VK_DELETE)){

}
if(GetAsyncKeyState(VK_F1)){

}
}

The code I'm testing is the one I put there, but I need the user id to be saved in the txt file but I can't do it.

Insufficient information. Is this some game you've written? What is this code you've posted?

What you've posted isn't going to work as the code is going to run once and then quit.

I haven't written the game, but I manage the game, but I don't have enough knowledge of C ++ to do what I want to do.

Well, that changes things vastly. Your idea isn't going to work at all unless you can get all the users to install your little spyware app. But yeah, "Hey, everyone needs to install this app so I can catch you cheating" isn't going to go over well.

The GetAsyncKeyState only looks at the keyboard on the machine it's running on, namely YOURS. It will NOT examine keyboards of remote machines.

Thank you for answering me, I think I had a good idea but I see that it is not possible. I will try to combat the hack in another way.

That's not the way to do it. You need to keep a rotating buffer of the last three keys pressed so you can make sure all three were pressed in the right order. After that happens THEN you need to save the password and ID. I'm not sure how to go about this without modifying the source code of the game. That's because I don't know what context the code you have shown will run in.

Actually, you probably should not save the password and shouldn't even have access to it. That is a security issue waiting to happen.
