How to setup internal virtual server and get TLS 1.3 keys from external virtual server via sideband?

Hi, We have started evaluating LTM and as part of integration for decrypting PFS with BIG-IP VE , I have attempted to create internal virtual server to which a sideband connection from external virt...

Hi Daniel_Wolf ,

Yes, similar to that. Post/copy TLS 1.3 secrets to an internal device API listening on http/https.

I'm out. Since you did not further specify your requirements I must assume that you plan do record sensitive data from a production environment. I have a bad feeling about permanently storing such data without any filters.

  We don't actually log those keys to disk, we keep them in memory (protected) and process with the traffic mirrored to the device, once done we rollout keys from device memory. Deployment would be like the one described in the article https://devcentral.f5.com/s/articles/lightboard-lesson-perfect-forward-secrecy-inspection-visibility...
  Deployment:
  External Client ----> Big IP ------> Internal Servers
  External Virtual Server
  |
  | TLS 1.3 keys (Sideband TCP)
  v
  BigIP Internal Virtual Server ---------> Pool (HTTP/HTTPS) ---> Pool Device (HTTP/HTTPS Internal Detection Device )
  
  In this deployment from External Virtual Server to Internal Virtual Server the TLS 1.3 keys are shared via TCP sideband, this part is OK and I am able to see that data on the wire.
  Now to share keys from Internal Virtual Server to the Pool and Pool device, how do we configure HTTP/HTTPS authentication?
