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。

    username: str
    email: str | None = None
    full_name: str | None = None
    disabled: bool | None = None


class UserInDB(User):
    hashed_password: str


pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_scheme = OAuth2PasswordBearer(
    tokenUrl="token",
    scopes={"me": "Read information about the current user.", "items": "Read items."},
)

app = FastAPI()

    username: str
    email: str | None = None
    full_name: str | None = None
    disabled: bool | None = None


class UserInDB(User):
    hashed_password: str


pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_scheme = OAuth2PasswordBearer(
    tokenUrl="token",
    scopes={"me": "Read information about the current user.", "items": "Read items."},
)

app = FastAPI()

=== "Windows PowerShell"

    <div class="termy">

    ```console

    ```

    </div>

=== "Windows Bash"

    Or if you use Bash for Windows (e.g. <a href="https://gitforwindows.org/" class="external-link" target="_blank">Git Bash</a>):

    <div class="termy">

    ```console
    $ source ./env/Scripts/activate
    ```

    </div>

It also supports running <a href="https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker#pre_start_path" class="external-link" target="_blank">**previous steps before starting**</a> with a script.

Há também suporte para executar <a href="https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker#pre_start_path" class="external-link" target="_blank">**passos anteriores antes de iniciar**</a> com um script.

!!! tip

Es unterstützt viele sichere Hashing-Algorithmen und Werkzeuge, um mit diesen zu arbeiten.

Der empfohlene Algorithmus ist „Bcrypt“.

Installieren Sie also PassLib mit Bcrypt:

<div class="termy">

```console
$ pip install "passlib[bcrypt]"

---> 100%
```

</div>
