How can I use cryptography with JavaScript?

Hello everyone, is there already cryptography plugin support in JavaScript? I want to encrypt messages before sending them on websocket.

Seems like that plugin has no javascript interface (yet?)

At least the binary data object has though. construct.net/en/make-games/manuals/construct-3/scripting/scripting-reference/plugin-interfaces/binary-data

So what you'd have to do in the meantime is create a little (async) helper function in the eventsheet that you call just for encrypting.

runtime.callFunction("encrypt", [params]).then(() => {
	// send via websocket
}

I want to encrypt messages before sending them on websocket.

Connect to a secure websocket (wss: - the WebSocket equivalent of https:), and this happens automatically, so you don't need to do any encryption or decryption yourself.

If you do want to write cryptography code in JavaScript for any other reason though, you have the full browser built-in Web Crypto API at your disposal.
