I have found only information pertaining to X-pack + elasticsearch for TLS/SSL and HTTPS.
Does the X-Pack license need to be valid in order to allow elasticsearch services to use TLS/HTTPS ?
Are there other tools or alternatives for encrypting the network traffic from elasticsearch endpoint that do not make use of X-Pack?
It seems like I am missing an important step here. If the only way to create HTTPS elasticsearch endpoints is with x-pack, what about groups that do not want to use x-pack?
