### Using `mc encrypt` (recommended)

MinIO automatically encrypts all objects on buckets if KMS is successfully configured and bucket encryption configuration is enabled for each bucket as shown below:

```
mc encrypt set sse-s3 myminio/bucket/
```

Verify if MinIO has `sse-s3` enabled

```
mc encrypt info myminio/bucket/
Auto encryption 'sse-s3' is enabled
```

### Using environment (not-recommended)

		subtle.XORBytes(dst[:x.blockSize], src[:x.blockSize], iv)

EncryptionConfiguration stores the complete configuration for encryption providers.
It also allows the use of wildcards to specify the resources that should be encrypted.
Use '*.<group>' to encrypt all resources within a group or '*.*' to encrypt all resources.
'*.' can be used to encrypt all resource in the core group.  '*.*' will encrypt all
resources, even custom resources that are added after API server start.
