We need to install `PyJWT` to generate and verify the JWT tokens in Python.

- [KEK](#kek): A secret and unique key used to en/decrypt the OEK and never stored anywhere. It is(re-)generated whenever en/decrypting an object using an external secret key and public parameters.
- [EK](#ek): An external secret key - either the SSE-C client-provided key or a secret key generated by the KMS.

## Anwendungsfälle { #use-cases }

Einige Anwendungsfälle sind:

* Konvertieren von Nicht-JSON-Requestbodys nach JSON (z. B. <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Dekomprimierung gzip-komprimierter Requestbodys.
* Automatisches Loggen aller Requestbodys.

## 警告

大量のバックグラウンド計算が必要であり、必ずしも同じプロセスで実行する必要がない場合 (たとえば、メモリや変数などを共有する必要がない場合)、<a href="https://www.celeryproject.org/" class="external-link" target="_blank">Celery</a> のようなより大きな他のツールを使用するとメリットがあるかもしれません。

## 경고

만약 무거운 백그라운드 작업을 수행해야하고 동일한 프로세스에서 실행할 필요가 없는 경우 (예: 메모리, 변수 등을 공유할 필요가 없음) <a href="https://docs.celeryq.dev" class="external-link" target="_blank">`Celery`</a>와 같은 큰 도구를 사용하면 도움이 될 수 있습니다.
