 [ ] Refine protocol using the implementation (and update stuff that got changed in impl)
 [ ] Finish implementing the protocol
 [ ] Update the protocol file with the latest structs and stuff
+
+## Protocol todo:
+
+[ ] Figure out how a message and message ack payload will look
+[ ] Figure out server responses (hopefully manages to be stuck in a 512 bit block as well)
+
+
+## client todo:
+
+[ ] Check for key when turned on
+	[ ] generate key and register if no key is preset, and save it after registration is done
+	[ ] if key is present, start by getting messages (which makes sure we are signed in)
