I am not an engineer. I am simply testing myself by trying to build a LITTLE website for a local chat purpose. I have built all the website but I face a problem. For example, if someone send a text to another one, the data are sent to a server, but are not encrypted. I have tried to imagine how i can secure data sent to server but i cannot. I simply encrypt them to the database (using php). The same for data sent from server to client. even if i can encrypt data in the server before sending to the client, i will not be able to decrypt them in the client. any help (giving a solution or saying it possible or not) is welcome.
