Secure pairing, as you said, is one use. You need to ensure that the two devices involved are exactly the ones you think they are, and WiFi or Bluetooth don’t work because they see everything in range. But it’s much higher bandwidth to use something like a QR code, where you can send several thousand bits simultaneously. It’s pretty easy to send and receive QR codes using APIs already available in iOS and Mac OS. You can send an entire cryptographic key, and use that to bootstrap secure communication over traditional networking. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
