I have been searching the web and here on how to create an encrypted chat server/client. And I think I got pretty confused now.
Firstly, I created a chat server/client from the free example Knock Knock Server from the Java Examples. So far, everything is working nicely, until I want to encrypt both server and clients.
Secondly, where do I start the encryption first? From the server then to the client? Am I suppose to use that Java Tool to create an encryption file for the server and share it with the clients?
Lastly, I am so confused after looking at so many tutorials on encryption, I don't know what is best for my situation. Can anyone help direct me to the correct tutorial website? Thanks a lot.
P.S. I do not know what kind of encryption tag I am suppose to use. Please edit that for me. Thank you.
I suggest you read about Transport Layer Security (TLS); It is probably the simplest reasonable approach to security and has been widely adopted (e.g. https and ftps).
In a sentence, it works by establishing a "secure channel" for your existing protocol to communicate over.
