[FONT=Helvetica Neue]answerhub copy: How to create LoginServer and LoginClient, using UE4 networking? - Multiplayer & Networking - Unreal Engine Forums

Please, help me to understand how to create login procedure with LoginName and Password, using UE4 networking.
[FONT=Helvetica Neue]1) I need to create Login Server, using UE4. Is it possible, with compiling with “SERVER” target directive? This server need to accept connections using LoginName and Password.
[FONT=Helvetica Neue]2) I need to create Client application, which will connect to server by user LoginName and Password.
[FONT=Helvetica Neue]3) I need ability to send server-client messages (packets) or RPC’s.
[FONT=Helvetica Neue]So question is:
[FONT=Helvetica Neue]a) How to create server on particular IP End Point, where to configure it?
[FONT=Helvetica Neue]b) How to connect to particular IP End Point from client, with setting IP address programmatically in code?
[FONT=Helvetica Neue]c) How to send LoginName/Password using encrypted manner, is there native UE4 such ability for passwords? or i need to create my own encrypting and then send encrypted data?
[FONT=Helvetica Neue]d) Is there native UE4 netwroking encrypting not only login data, but also whole networking stream?
[FONT=Helvetica Neue]please help.

PS: i really dont want to create my own Socket networking, i want to know, may be i can do the same, using native UE4 networking.
