[Vortex] About verify server identity in tls profile

[Scott Zhang]

Hello.
  I am able to use vortex_tls_start_negotiation to start the tls
session with server. That works.
  What I want to ask is "is there way to confirm the server I am
connecting to is my server?" eg: verify the public key? I looked over
the tls related function but can't find how to do it.
  Do I need to look into the openssl below votex?


Regards.
Scott
