Passworded worlds

[willneedit]

To protect a world against content theft, there has to be a means to encrypt the world data, and remain the metadata and the screenshot in cleartext.

• A user can set up a password, locally.
• If the client loads the world locally (in offline mode), and it's passwordrd and the set up password matches, it loads up.
• ... if it doesn't match, the client asks the user.
• Now, when the (server admin) user and sets up the world in the server or the host mode, the password (encrypred for the server) is delivered to the server itself.
• Clients connecting to the passworded server delivers the URL of the encrypted world, _and the password (encrypted for the connected clients).
• Clients decrypt the world file in memory once it's ready to show. The cached file is still encrypted.
