Whatsapp does end-to-end encryption

It says it’s the “largest deployment of end-to-end encryption ever”.I’ve no idea if that’s true which is slightly worrying. It seems the sort of thing I ought to know. There are 500 million downloads of Whatsapp in the Play Store, though, so it seems about right.  Anyway, it’s working on Android on messages that aren’t group, photo or video messages. Other platforms coming soon.  Forward secrecy too. Good news.

Whatsapp’s rollout of strong encryption to hundreds of millions of users may be an unpopular move among governments around the world, whose surveillance it could make far more difficult. Whatsapp’s user base is highly international, with large populations of users in Europe and India. But Whatsapp founder Jan Koum has been vocal about his opposition to cooperating with government snooping. “I grew up in a society where everything you did was eavesdropped on, recorded, snitched on,”

Here in the UK we’ve sidled into such a world.  Maybe we can sidle back out of it, maybe we can’t.
