This protects against accidental overwrites or deletes of objects, allows previous versions to be retrieved.

When you DELETE an object, all versions remain in the bucket and MinIO adds a delete marker, as shown below:

## Code Examples

[Using minio-go library](https://github.com/minio/minio/blob/master/docs/extensions/s3zip/examples/minio-go/main.go)
[Using AWS JS SDK v2](https://github.com/minio/minio/blob/master/docs/extensions/s3zip/examples/aws-js/main.js)
[Using boto3](https://github.com/minio/minio/blob/master/docs/extensions/s3zip/examples/boto3/main.py)

As the initial step, fetch the private key and certificate of the root identity:

```sh
curl -sSL --tlsv1.2 \
     -O 'https://raw.githubusercontent.com/minio/kes/master/root.key' \
     -O 'https://raw.githubusercontent.com/minio/kes/master/root.cert'
```

### 2. Set the MinIO-KES configuration

```sh
export MINIO_KMS_KES_ENDPOINT=https://play.min.io:7373
export MINIO_KMS_KES_KEY_FILE=root.key
