Secure Socket StartUp

[eowe27]

Hi,
I want esp32 and android to connect securely. I can set up a server in esp32 with tcp socket also android can connect as a client. Now I need to make it safe. TCP socket will still exist, but data will be encrypted with private key. This private key will be randomly generated on android i need to send this to esp32. I learned that I need to do this with tls socket. (sending private key)
But I couldn't find any starting code or source. I need your help.
