I did this once in C with just OpenSSL and I can't recommend against that enough! I learned a lot (about security) and it was fun, but, you're not valuing your own time at that point. If I had that same problem today, I think I'd use one of Go, Rust or Racket instead. They're a bit easier to set up and probably a bit less of a security nightmare. If you're using Unity, Normcore is the one I hear most often. I think Photon is the most popular though. The built-in networking in Unreal is pretty solid if you're using that too.
