常用代码hashlib模块 --加密代码的使用

参考：https://www.cnblogs.com/alex3714/articles/5161349.html

常用代码模板： 

import hashlib

password = 123
md5_obj = hashlib.md5() # 生成一个md5实例
md5_obj.update(password.encode())
md5_password = md5_obj.hexdigest()
print("passwd:",password,md5_password)

模块讲解说明：

hashlib模块　　

用于加密相关的操作，3.x里代替了md5模块和sha模块，主要提供 SHA1, SHA224, SHA256, SHA384, SHA512 ，MD5 算法
