### Verify auto-encryption

> Note that auto-encryption only affects requests without S3 encryption headers. So, if a S3 client sends
> e.g. SSE-C headers, MinIO will encrypt the object with the key sent by the client and won't reach out to
> the configured KMS.

To verify auto-encryption, use the following `mc` command:

```
mc cp test.file myminio/bucket/
