### Technical details about the JWT "subject" `sub`

The JWT specification says that there's a key `sub`, with the subject of the token.

It's optional to use it, but that's where you would put the user's identification, so we are using it here.

トークンの有効期限を表す`timedelta`を作成します。

JWTアクセストークンを作成し、それを返します。

### JWTの"subject" `sub` についての技術的な詳細

JWTの仕様では、トークンのsubjectを表すキー`sub`があるとされています。

使用するかどうかは任意ですが、`sub`はユーザーの識別情報を入れるように規定されているので、ここで使用します。

JWTは、ユーザーを識別して、そのユーザーがAPI上で直接操作を実行できるようにする以外にも、他の用途で使用されることがあります。

例えば、「車」や「ブログ記事」を識別することができます。
