Most Efficient way of Encrypted Chat
I'm creating a server where people can come and talk to each other. I'm mostly doing it for a fun project. I'm using RSA for encryption/decryption, so only the clients will know what's being said. I don't want the server to handle any decrypted text.
My question is, what's the most efficient way of doing this? From my understanding, I'm going to have to give everybody each other's public keys. And once a client says something, it's going to have to encrypt it to each person individually using their respective public key, isn't it? To me that seems extremely inefficient.
Is there a better way to do this?
