KMIP Engine general query


I am interested to know more about the KMIP engine which was added since 1.2.

I looked at the steps in the tutorial about how to setup the KMIP engine, with regarding to the KMIP listener, can you answer my queries:

  1. After I enable KMIP engine, KMIP Listener port is 5696, is the KMIP listener working only on the raw TCP port, or also working on top of the https?
  2. Any example in the hashicorp about how to interact with this KMIP port, such as get a secret?
