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

Erstellen Sie eine Variable `ALGORITHM` für den Algorithmus, der zum Signieren des JWT-Tokens verwendet wird, und setzen Sie sie auf `"HS256"`.

Erstellen Sie eine Variable für das Ablaufdatum des Tokens.
