    例如，用它读取和校验其它系统（如 Django）生成的密码，但要使用其它算法，如 Bcrypt，生成新的哈希密码。

    同时，这些功能都是兼容的。

接下来，创建三个工具函数，其中一个函数用于哈希用户的密码。

第一个函数用于校验接收的密码是否匹配存储的哈希值。

第三个函数用于身份验证，并返回用户。

```Python hl_lines="7  48  55-56  59-60  69-75"
{!../../../docs_src/security/tutorial004.py!}
```

!!! note "笔记"

    查看新的（伪）数据库 `fake_users_db`，就能看到哈希后的密码：`"$2b$12$EixZaYVK1fsbw1ZfbX3OXePaWxn96p36WQoeG6Lruj3vjPGga31lW"`。
