Python实验-字典攻击

# 字典攻击
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')#写模式打开文件
    for i in libararys:
        dic.writelines(i)
        dic.writelines("\n")
    dic.close()
#x = hashlib.md5("123".encode(encoding="utf-8")).hexdigest()#hash算法存储密码
#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("你的密码是：{}".format(passwords))
    file.close()
if __name__ == "__main__":
    #lowercase = 'abcdefghijklmnopqrstuvwxyz'#字符组合
    #uppercase = 'ABCDEFGHIJKLMNOPQRS'
    #digits = '0123456789'
    word = "xiaowng2067"
    #special = """!"#$%&'( )*+,-./:;<=>?@[]^_`{|}~"""
    #word = lowercase + uppercase + digits + special
    starttime = datetime.datetime.now() # 获取当前时间
    print(time.strftime("%Y%m%d%H%M%S", time.localtime(time.time())))
    generatelibary(word,length=6)  #生成8位数字字典
    #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)#时间

六位密码测试效果最好，八位太长，需要时间过多
