This reminds me of the good old days before signal, back when it was still called SmsSecure / TextSecure / Silence. This was pretty much the same concept but on top of SMS. I loved it
Thanks :) Have not witnessed those good old days myself but have to check out! I assume the encryption flow has to be flawless UX/UI to win the consumers for such a tool
It was pretty much a simple "toggle encryption" button, when you pressed it and your friend also had Silence it would ask them if they want to start encryption, you pressed yes and you were encrypted. The only thing was that when you changed phone / reinstalled you would receive the encrypted message and you had to tell your friend to stop and restart the encryption
