WhatsApp's Signal Protocol integration is now complete

At Open Whisper Systems, our goal is to make private communication simple. A year ago, we announced a partnership with WhatsApp and committed to integrating the Signal Protocol into their product, moving towards full end-to-end encryption for all of their users by default.
