Feature: send single unencrypted SMS without breaking the keys
Created by: matya
Allow sending one time not encrypted SMS
Having some tracking app on the phone, that can receive SMS commands from a given number of other phones is quite usual, like Eset anti virus or Cerberus.
When both parties are using silence, and a handshake has been successfully done, the given app can not receive the SMS based commands without breaking the encryption completely, since that requires an unencrypted command being sent via plain text.
Even this is possible and "easy", it requires the following KEX, which would not really be a necessity.
This proposal is to allow single SMS being sent without discarding the established encryption, for remote control purposes, just like explained.
