WhatsApp rolls out end-to-end encryption to its 1 billion+ users

The update to the infrastructure means that not even WhatsApp can view the data, and has been activated for any and all users of the famed instant-messaging app. Whether you're still rocking WhatsApp on the BlackBerry OS or running the app on your iPhone, your correspondence cannot be snooped upon by outsiders.
The move by WhatsApp to deliver end-to-end encryption seems timely, given the much-publicized recent skirmish between Apple and the FBI. Though it was never in much doubt, today's update affirms Facebook's stance as an ally to Apple in the protection of Joe Public's personal data.
Whether this move will prompt the likes of the FBI to demand loopholes to circumvent these digital blockades, only time will tell. But with one billion worldwide users, WhatsApp's position among the foremost IM apps has only been consolidated by the new encryption.
