WhatsApp is now one of the strongest messaging apps you can find on Android — thanks to new end-to-end encryption for messages — and the features may soon come to the iOS version as well. That means messages send from your iOS device would be totally secure and not have the ability to be decrypted by WhatsApp at all — no matter what. Other apps offer similar end-to-end security, but WhatsApp is by far the largest of the bunch.

The new feature comes from a partnership with Open Whisper Systems, best known for their TextSecure apps. Open Whisper CTO Moxie Marlinspike says it took six months to nail down the code for such a large deployment.

Only the two parties involved in the chat will be able to see the messages, so even if WhatsApp were asked to hand over the messages to law enforcement (or the NSA), they won't be able to. The new feature heads to the Android version of WhatsApp today, but we'll be watching closely to see if it hits iOS devices soon as well.
