Technology used

  • C++

Resources Used

Note

  • FreeConsole(): Detaches the calling process from its console. It helps in running the program in background.
  • GetAsyncKeyState() can't tell the difference between upper and lower case letters. We would need to take SHIFT and CAPSLOCK into account in order to determine case.

How to Run Keylogger [Using an IDE]

  1. Clone this repository from GitHub: $ https://github.com/aksuman055/keylogger

  2. Open keylogger.cpp and change the maximum number of key strokes you wish to record (max constant)

  3. Compile with MinGW: g++ keylogger.cpp -o keylogger.exe

  4. Run keylogger.exe

  5. The program will terminate after a certain number(max constant) of key strokes.

  6. Inspect log.txt

Output

log.txt output:
