- For instructions on using KES for encrypting the MinIO backend, follow the [KMS Quick Start](https://github.com/minio/minio/tree/master/docs/kms). The SSE-S3 configuration setup also supports MinIO KMS backend encryption.

## FAQ

> Why is this change needed?

Before, there were two separate mechanisms - S3 objects got encrypted using a KMS,

## Auto Encryption

Auto-Encryption is useful when MinIO administrator wants to ensure that all data stored on MinIO is encrypted at rest.

### 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:

```
