Therefore, compression is disabled when encrypting by default, and must be enabled separately.

Consult our security experts on [SUBNET](https://min.io/pricing) to help you evaluate if
your setup can use this feature combination safely.

To enable compression+encryption use:

```bash

  // Allowed indicates whether or not the admission request was permitted.
  optional bool allowed = 2;

  // Result contains extra details into why an admission request was denied.
  // This field IS NOT consulted in any way if "Allowed" is "true".
  // +optional
  optional k8s.io.apimachinery.pkg.apis.meta.v1.Status status = 3;

  // The patch body. Currently we only support "JSONPatch" which implements RFC 6902.
  // +optional
