Python學習記錄

今天課上跟老師學習一個叫做字典攻擊的程式，因為自己沒有學到位，聽得雲裡霧裡的，但還是跟著老師敲，準備以後自己慢慢學習。

# 字典攻擊
import itertools # 迭代器
import datetime
import hashlib
import time
def generatelibary(library, length=8):
    libararys = itertools.product(library,repeat=length)
    dic = open("paswordlirbarys.txt","w",encoding='utf-8')#寫模式開啟檔案
    for i in libararys:
        dic.writelines(i)
        dic.writelines("\n")
    dic.close()
#x = hashlib.md5("123".encode(encoding="utf-8")).hexdigest()#hash演算法儲存密碼
#202cb962ac59075b964b07152d234b70
#print(x)
def dict_attack(path,password):
    file = open(path)
    for passwords in file:
        #print(passwords)
        passwords = passwords.split("\n")[0]
        if password == hashlib.md5(passwords.encode(encoding="utf-8")).hexdigest():
            print("你的密碼是：{}".format(passwords))
if __name__ == "__main__":
    #lowercase = 'abcdefghijklmnopqrstuvwxyz'#字元組合
    #uppercase = 'ABCDEFGHIJKLMNOPQRS'
    #digits = '0123456789'
    word = "xiaowng2067"
    #special = """!"#$%&'( )*+,-./:;<=>
 
[email protected][]^_`{|}~"""
    #word = lowercase + uppercase + digits + special
    starttime = datetime.datetime.now() # 獲取當前時間
    print(time.strftime("%Y%m%d%H%M%S", time.localtime(time.time())))
    generatelibary(word,length=6)  #生成8位數字字典
    #dict_attack("paswordlirbarys.txt","05213bc82bacf7312806baf095038402")
    endtime = datetime.datetime.now()
    print(time.strftime("%Y%m%d%H%M%S", time.localtime(time.time())))
    print('The time cost: ')
    print(endtime - starttime)#時間
