   `keytool -export -alias test-node -keystore test-node.jks -storepass keypass -file test-node.crt`
4. Import the node certificate in the client's keystore:

    private byte[] macSigningKey;
    private boolean bypass = false;
    private int updates;
    private int signSequence;

See <https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lock-overview.html> for AWS S3 spec on object locking and permissions required for object retention and governance bypass overrides.

### Set legal hold on an object

PutObject API allows setting legal hold using `x-amz-object-lock-legal-hold` header.

```sh

                    c.setting("xpack.security.http.ssl.keystore.path", "test-node.jks");
                    c.keystore("xpack.security.transport.ssl.keystore.secure_password", "keypass");
                    c.keystore("xpack.security.http.ssl.keystore.secure_password", "keypass");
                    // copy keystores & certs into config/
                    c.extraConfigFile(nodeKeystore.getName(), nodeKeystore);
