Python常用模块 之 hashlib模块——简单实现实现登录注册

（唯一要求：使用hashlib中的md5进行加密！）

 import hashlib
import re

def denglu():
    user1 = input('请输入你的账号:')
    pwd  = input('请输入你的密码:')
    count = 0
    with open('json1.txt','r') as f:
        for i in f:
            user,passwd = i.split('|')   
            result_pwd = re.findall(r'\\S+',passwd)[0]   
            
            # 加盐操作
            pwd_a = '加密加密' + pwd + '#￥@￥@#@@#'
            res = hashlib.md5(pwd_a.encode())
            res_pwd = res.hexdigest()
            
            if user1 ==user and res_pwd == result_pwd:
                print('输入正确')
                count +=1

        if count ==0:
            print('输入错误')

def zhuce():
    usr = input('请输入你要注册的名字:')
    pwd = input('请输入你要注册的密码:')
    pwd_n = '加密加密' + pwd + '#￥@￥@#@@#'
    res_pwd = hashlib.md5(pwd_n.encode())
    pwd = res_pwd.hexdigest()
    with open('json1.txt','a+') as f:
        f.write(usr+'|'+pwd + '\\n')

while True:
    try:
        a = int(input('请输入你要执行的操作：1.注册，2登录,3.退出\\n:'))
    except ValueError as f:
        print('问题是：%s'%f)
        break
    if a == 1:
        zhuce()
    elif a == 2:
        denglu()
    elif a == 3:
        break
