Red de democratie stop #chatcontrol !! . Dit is zo een extreem slecht wetsvoorstel dat ik er voor als mascotte van de Piratenpartij ZuidHolland voor naar 020 afreis. Lees hier wat het probleem is: https://chatcontrole.nl/
@LovesTha@emsquared@og it can, and Signal has done SMS-encryption when it was still called Textsecure, but that was always independent of data. AFAIK what you describe has never been and while it can work, the limits of SMS make the overhead difficult to manage.
Data has just completely replaced it and what you describe seems to have made it a good choice, otherwise people will assume encryption where there is not, which can be quite dangerous.
