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）

JWTトークンの署名に使用するアルゴリズム`"HS256"`を指定した変数`ALGORITHM`を作成します。

トークンの有効期限を指定した変数`ACCESS_TOKEN_EXPIRE_MINUTES`を作成します。

レスポンスのトークンエンドポイントで使用するPydanticモデルを定義します。

新しいアクセストークンを生成するユーティリティ関数を作成します。

Of course, the attackers would not try all this by hand, they would write a program to do it, possibly with thousands or millions of tests per second. And would get just one extra correct letter at a time.

But doing that, in some minutes or hours the attackers would have guessed the correct username and password, with the "help" of our application, just using the time taken to answer.

#### Fix it with `secrets.compare_digest()`

### Faite en python moderne

Tout est basé sur la déclaration de type standard de **Python 3.8** (grâce à Pydantic). Pas de nouvelles syntaxes à apprendre. Juste du Python standard et moderne.

Si vous souhaitez un rappel de 2 minutes sur l'utilisation des types en Python (même si vous ne comptez pas utiliser FastAPI), jetez un oeil au tutoriel suivant: [Python Types](python-types.md){.internal-link target=_blank}.

                                    {
                                        "title": "Square",
                                        "maxItems": 2,
                                        "minItems": 2,
                                        "type": "array",
                                        "prefixItems": [
                                            {"$ref": "#/components/schemas/Coordinate"},

Ele é designado para ser integrado com esse _cluster_ Docker Swarm com Traefik e HTTPS descrito acima.

Você pode gerar um projeto em cerca de 2 minutos.

O projeto gerado tem instruções para fazer o _deploy_, fazendo isso leva outros 2 minutos.

## Alternativamente, faça o _deploy_ **FastAPI** sem Docker

Você pode fazer o _deploy_ do **FastAPI** diretamente sem o Docker também.
