Python实验-字典攻击！你的密码分分钟被搞定！

1. 
   # 字典攻击

2. import itertools # 迭代器

3. import datetime

4. import hashlib

5. import time

6. def generatelibary(library, length=8):

7. libararys = itertools.product(library,repeat=length)

8. dic = open("paswordlirbarys.txt","w",encoding='utf-8')#写模式打开文件

9. for i in libararys:

10. dic.writelines(i)

11. dic.writelines("\n")

12. dic.close()

13. #x = hashlib.md5("123".encode(encoding="utf-8")).hexdigest()#hash算法存储密码

14. #202cb962ac59075b964b07152d234b70

15. #print(x)

16. def dict_attack(path,password):

17. file = open(path)

18. for passwords in file:

19. #print(passwords)

20. passwords = passwords.split("\n")[0]

21. if password == hashlib.md5(passwords.encode(encoding="utf-8")).hexdigest():

22. print("你的密码是：{}".format(passwords))

23. if __name__ == "__main__":

24. #lowercase = 'abcdefghijklmnopqrstuvwxyz'#字符组合

25. #uppercase = 'ABCDEFGHIJKLMNOPQRS'

26. #digits = '0123456789'

27. word = "xiaowng2067"

28. #special = """!"#$%&'( )*+,-./:;<=>?@[]^_`{|}~"""

29. #word = lowercase + uppercase + digits + special

30. starttime = datetime.datetime.now() # 获取当前时间

31. print(time.strftime("%Y%m%d%H%M%S", time.localtime(time.time())))

32. generatelibary(word,length=6) #生成8位数字字典

33. #dict_attack("paswordlirbarys.txt","05213bc82bacf7312806baf095038402")

34. endtime = datetime.datetime.now()

35. print(time.strftime("%Y%m%d%H%M%S", time.localtime(time.time())))

36. print('The time cost: ')

37. print(endtime - starttime)#时间

 

六位密码测试效果最好，八位太长，需要时间过多
