title: Client-Server Secure communication within application
body: <p>I want to create a game within the Unity game engine in C# with .NET where I can securely connect out to a private server, and read and write data from/to the server. I understand how to do this in a non-secure way, where I would setup a private SQL database with a webpage interface between the two.</p>
  <p>My problem comes here, I know if I want the web interface to be public, I need credentials to connect to the server, such as an Auth key, or username and password. However, in order to use those, then the auth-key would need to ship with the game as a file, or would need to be written directly into the codebase. I know that users can decompile games, and access these files and get the credentials if I include them, which means that option is off the table as far as I am aware.</p>
  <p>It is my understanding that even with this layer between the database and the client, someone could still find the url for the interface between them, and then send custom function calls to this url as I will be doing in the game program. Wouldn't this lead to the same conclusion as having the database be open?</p>
  <p>If anyone has answers to this, or resources where I can learn about this process, please let me know! I have never done server-side programming before and have also never thought about security before in my life.</p>
