Block Unwanted Participants

Hello, people I do not know can connect to my TCP server without using a client. To prevent this, I want it to perform a verification before connecting to the server, but I have no idea how to do this. I think I need to use a certificate like simpletcp.crt. If this is done with a certificate, can you give me a short example of how to do it?

Hi @nexquery you could use SSL certificates for this, you would have to install them in the server's operating system for each client. Another approach would be to use Settings.PermittedIPs to specify the IP addresses you would like to allow to connect (if known a priori). Yet another approach would be, within whatever messaging architecture you build on top of this library, to authenticate requestors prior to allowing them to interact.
