This article introduces the knowledge of "how to write MD5 scripts based on python". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Development ideas

1. Automatically generate dictionaries through string module

2. Use the permutations () function to arrange all the dictionaries

3. Use md5 module to convert fully arranged dictionaries.

4. Multithreading is used to perform md5 collisions on 5-bit 18-bit strings respectively to prevent it from taking too long (although it will take a long time now).

Md5 collision function def md5_poj (self, md5_value, k): if len (md5_value)! = 32: print ("error") return md5_value = md5_value.lower () # permutations () full permutation for item in permutations (all_letters K): item = ".join (item) if item = =" hongrisec@2019 ": print (item) if md5 (item.encode ()) .hexdigest () = = md5_value: print ('\ n success:'+ md5_value +'= = >'+ item) self.__mdfive = 1

Where if len (md5_value)! = 32 determines whether the input md5 is 32-bit

Main function def main (self): NT_md5 = input ("Please fill in MD5:") start_time = time () t_list = [] print ("querying...") # add thread t_first = threading.Thread (target=self.md5_first, args= (NT_md5,)) t_first.daemon = 1 t_first.start () for k in range (5 18): t = Process (target=self.md5_poj, args= (NT_md5, k)) # t = threading.Thread (target=self.md5_poj, args= (NT_md5) K) t.daemon = 1 # daemon t_list.append (t) # start all threads for i in t_list: i.start () # end all threads when _ _ mdfive = = 1 while 1: if self.__mdfive: break Print ("\ nquery ends!")
