Import the modules installed.

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

To generate a secure random secret key use the command:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

And copy the output to the variable `SECRET_KEY` (don't use the one in the example).

## 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：

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

そして、出力された文字列を変数`SECRET_KEY`にコピーします。（例に記載している秘密鍵は実際に使用しないでください）

De nombreux développeurs et équipes dépendent déjà de **FastAPI** pour leurs projets (y compris moi et mon équipe).

Mais il y a encore de nombreuses améliorations et fonctionnalités à venir.

**FastAPI** a un grand avenir devant lui.

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

### Concurrent Burgers

You go with your crush to get fast food, you stand in line while the cashier takes the orders from the people in front of you. 😍

Um einen sicheren zufälligen geheimen Schlüssel zu generieren, verwenden Sie den folgenden Befehl:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

Und kopieren Sie die Ausgabe in die Variable `SECRET_KEY` (verwenden Sie nicht die im Beispiel).
