enable HTTPS server on Zephyr RTOS

[NarendraSonawane1]

I am trying to enable HTTPS server with reference of this
https://github.com/civetweb/civetweb/blob/master/examples/embed_certificate/ec_example.c and https://github.com/civetweb/civetweb/blob/master/examples/embedded_c/embedded_c.c#L1145

I have made changes in ciwetweb/http_server/main.c file as i dont have file system on board so i passed cert and key in array format.
as example given in above two links.

que 1:I have call this callback ::::like callbacks.init_ssl = init_ssl; but function is not getting call init_ssl()
que 2:can i use mbedtls library to enable HTTPS, if yes how to do it?
