 ### Connection data
 The connectionData parameter is any custom data of your choice that the client should send to the server. Usually, this should be some sort of ticket, room password or similar that will decide if a connection should be approved or not. The connectionData is specified on the Client side in the NetworkingConfig supplied when connecting. Example:
 ```csharp

-If Encryption is enabled, the connection handshake with the buffer will be encrypted AND authenticated. (AES-256 encryption and HMAC-SHA-256 authentication). Please note that if the key exchange is not signed, a man in the middle attack can be done. If you plan on sending authentication tokens such as steam tickets. It's strongly suggested that you sign the handshake.
