WhatsApp Rolls Out End-To-End Encryption to its Over One Billion Users As much as I despise Facebook, I do have to applaud the audacity of this move. What they've done in one fell swoop is make encryption easy for everyone who uses their service. And this is the type of thing that's needed in order for users to use encryption in an easy to use format that doesn't entail a lot of work. This is why PGP never really took off as it's a royal pain in the hind end for users to set up and use. I personally use Signal for text messaging, and it's pretty darned easy to use.
