### 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

// It fails if the object is encrypted and the HTTP headers don't contain
// SSE-C headers or the object is not encrypted but SSE-C headers are provided. (AWS behavior)
// DecryptObjectInfo returns 'ErrNone' if the object is not encrypted or the
// decryption succeeded.
//
// DecryptObjectInfo also returns whether the object is encrypted or not.
