## Server-Side Encryption

MinIO supports two different types of server-side encryption ([SSE](#sse)):

- **SSE-C**: The MinIO server en/decrypts an object with a secret key provided by the S3 client as part of the HTTP request headers. Therefore, [SSE-C](#ssec) requires TLS/HTTPS.
- **SSE-S3**: The MinIO server en/decrypts an object with a secret key managed by a KMS. Therefore, MinIO requires a valid KMS configuration for [SSE-S3](#sses3).

But you can return a `JSONResponse` directly from your *path operations*.

It might be useful, for example, to return custom headers or cookies.

## Return a `Response` { #return-a-response }

In fact, you can return any `Response` or any sub-class of it.

/// tip

`JSONResponse` itself is a sub-class of `Response`.

Zuerst erstellen wir eine `GzipRequest`-Klasse, welche die Methode `Request.body()` überschreibt, um den Body bei Vorhandensein eines entsprechenden Headers zu dekomprimieren.

Wenn der Header kein `gzip` enthält, wird nicht versucht, den Body zu dekomprimieren.

Auf diese Weise kann dieselbe Routenklasse gzip-komprimierte oder unkomprimierte Requests verarbeiten.
