    !!! tip "Tipp"
        Bevorzugen Sie die `Annotated`-Version, falls möglich.

Achten Sie auf die Methode `__init__`, die zum Erstellen der Instanz der Klasse verwendet wird:

=== "Python 3.10+"

    ```Python hl_lines="12"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="12"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="13"

    {!> ../../../docs_src/security/tutorial004.py!}
    ```

!!! note
    If you check the new (fake) database `fake_users_db`, you will see how the hashed password looks like now: `"$2b$12$EixZaYVK1fsbw1ZfbX3OXePaWxn96p36WQoeG6Lruj3vjPGga31lW"`.

## Handle JWT tokens

Import the modules installed.

Create a random secret key that will be used to sign the JWT tokens.

Pay attention to the `__init__` method used to create the instance of the class:

=== "Python 3.10+"

    ```Python hl_lines="12"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="12"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="13"

## Parameter für die Enkodierung des Responsemodells

Ihr Responsemodell könnte Defaultwerte haben, wie:

=== "Python 3.10+"

    ```Python hl_lines="9  11-12"
    {!> ../../../docs_src/response_model/tutorial004_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="11  13-14"
    {!> ../../../docs_src/response_model/tutorial004_py39.py!}
    ```

さらに、ユーザーを認証して返す関数も作成します。

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

!!! note "備考"
    新しい（偽の）データベース`fake_users_db`を確認すると、ハッシュ化されたパスワードが次のようになっていることがわかります：`"$2b$12$EixZaYVK1fsbw1ZfbX3OXePaWxn96p36WQoeG6Lruj3vjPGga31lW"`

## JWTトークンの取り扱い

インストールした複数のモジュールをインポートします。

JWTトークンの署名に使用されるランダムな秘密鍵を生成します。

安全なランダム秘密鍵を生成するには、次のコマンドを使用します：
