If Elasticsearch has authentication enabled, the credentials can be supplied to MinIO via the `url` parameter formatted as `PROTO://USERNAME:PASSWORD@ELASTICSEARCH_HOST:PORT`.

To update the configuration, use `mc admin config get` command to get the current configuration.

```sh
$ mc admin config get myminio/ notify_elasticsearch

The default OpenSSL format for private encrypted keys is PKCS-8, but MinIO only supports PKCS-1. An RSA key that has been formatted with PKCS-8 can be converted to PKCS-1 using the following command:

```sh
openssl rsa -in private-pkcs8-key.key -aes256 -passout pass:PASSWORD -out private.key
```
