xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12
--------------------------------------------------

And must be configured as:
[source,yaml]
--------------------------------------------------
xpack.security.transport.ssl.enabled: true <1>
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12
--------------------------------------------------
<1> or `false`.

[float]
===== The `xpack.security.http.ssl.enabled` setting may be required

xpack.security.http.ssl.certificate: elasticsearch.crt 
xpack.security.http.ssl.key: elasticsearch.key 
xpack.security.http.ssl.certificate_authorities: [ "corporate-ca.crt" ]
--------------------------------------------------

And must be configured as either:
[source,yaml]
--------------------------------------------------
xpack.security.http.ssl.enabled: true <1>
xpack.security.http.ssl.certificate: elasticsearch.crt 
xpack.security.http.ssl.key: elasticsearch.key 
xpack.security.http.ssl.certificate_authorities: [ "corporate-ca.crt" ]
--------------------------------------------------
<1> or `false`.
