Encrypt data from server to client?

Question

Information Security

Can you tell me how to properly implement data encryption between the client and the server.
There is a web server, server and client.
I want the client to receive data from the web server once per session.
That is, I want to transfer encrypted data from the web server -> to the client, while then this data must be decrypted on the client, but only once per session.
What can you advise to use better, and is this method safe?

Answer 1

If there is "what to decrypt" and "how to decrypt", I can decrypt it exactly as many times as I want.))))
Use RSA using the session key.
