如何将密码转换为哈希值？

Question

我正在尝试为我的项目创建一个登录系统，我需要对用户密码使用散列，我不确定如何散列变量名称并将其转换为字节以给出密码的十六进制结果。

尝试使用：

hash_object = hashlib.md5(b(password))

和：

hash_object = hashlib.md5((password))

代码：

import hashlib

user = {}

username = input("What is your username? ")
password = input("What is your password? ")

hash_object = hashlib.md5((password))
print(hash_object.hexdigest())

错误：

Traceback (most recent call last):
  File "E:\loginsystem.py", line 8, in <module>
    hash_object = hashlib.md5((password))
TypeError: Unicode-objects must be encoded before hashing

Answer 1

使用.encode 方法对密码字符串进行编码。

import hashlib

user = {}

username = input("What is your username? ")
password = input("What is your password? ")

hash_object = hashlib.md5(passsword.encode('utf8'))
print(hash_object.hexdigest())
