这样一来，窃贼就无法在其它应用中使用窃取的密码（要知道，很多用户在所有系统中都使用相同的密码，风险超大）。

## 安装 `passlib`

Passlib 是处理密码哈希的 Python 包。

它支持很多安全哈希算法及配套工具。

本教程推荐的算法是 **Bcrypt**。

因此，请先安装附带 Bcrypt 的 PassLib：

<div class="termy">

```console
$ pip install passlib[bcrypt]

---> 100%
```

</div>

/// tip | "提示"

`passlib` 甚至可以读取 Django、Flask 的安全插件等工具创建的密码。
