Truly, I already asked the question in [stackoverflow](https://stackoverflow.com/questions/59307949/es-7-4-1-authentication-rest-api) but didn't receive an answer yet, so I also create a new topic here..

I’m a newbie in ES and I have a task in my new job to upgrade from 6.4.2 to 7.4.1 – From TCP client to Rest High Level API.

Previously we built the client like this (with SSL & Certificate):

```
Settings settings = Settings.builder()
      .put("xpack.security.user", String.format("%s:%s",esJavaUser,esJavaPassword))
      .put("cluster.name", esClusterName)
      .put("xpack.security.transport.ssl.enabled", xpackSecurityTransportSslEnabled)
      .put("xpack.ssl.certificate_authorities", xpackSslCertificateAuthorities)
      .build();

 client = new PreBuiltXPackTransportClient(settings);

```

Now, in rest API, it’s changed to this:

```
final CredentialsProvider credentialsProvider =
        new BasicCredentialsProvider();
credentialsProvider.setCredentials(AuthScope.ANY,
        new UsernamePasswordCredentials(esJavaUser, esJavaPassword));

RestClientBuilder restClientBuilder = RestClient.builder(hosts)
        .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder
                .setDefaultCredentialsProvider(credentialsProvider));
restHighLevelClient = new RestHighLevelClient(restClientBuilder);

```

With this build I set ES user and password by CredentialsProvider **but** what about `ssl.enabled` and `certificate_authorities”`? how should I provided them with rest API?

The documentation you are looking for is here: [Encrypted communication | Java REST Client [7.4] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/_encrypted_communication.html)

SSL is automatically enabled (or not) based on the scheme (protocol) in the `HttpHost` objects you pass to the builder.

```auto
RestClient.builder(hosts)

```

If you are using SSL, you want to pass `"https"` as the scheme (3rd argument) when you construct the `HttpHost` objects (`hosts`).

Unfortunately there is no simple means to pass `certificate_authorities` to the Rest client, you need to turn those certificates into a standard Java truststore.

You can probably find some sample code on the web ("convert PEM certificates to Java truststore"), but the gist of it is:

1. Open the certificate authority files as an `InputStream`
2. Create a X.509 certificate factory: `java.security.cert.CertificateFactory.getInstance("X.509")`
3. Call `generateCertificates` on the certificate factory to read those certificate files into java `Certificate` objects
4. Construct an empty `KeyStore` object
5. Add the loaded certificates as trusted entries
6. Pass that to `SSLContextBuilder.loadTrustMaterial`

Thank you very much!!

P.S. The documentaion not mention the certificate section you wrote in your answer, maybe you might want to add it... Thanks again!
