Limitations
-----------
+Message Replays
+---------------
+
+A message can be decrypted successfully multiple times. This means that a MITM
+server can send multiple copies of a message and they will successfully decrypt.
+
+To mitigate this it is recomendend that applications track the message indicies
+they have recieved and that they reject messages with indicies that they've
+already decrypted.
