@jiska @trusted_device Oh wow, that is an impressive amount of complexity in a wristwatch! I would never have expected to find IPSEC over Bluetooth in a device like this, although I can kind of understand why they went this route. The custom handshake protocol extensions look sketchy af though.

@jiska @trusted_device It's pretty sad that they don't open up their overall generally decent cryptographic designs more. Without you putting years of work into this, nobody outside apple would have ever known about any of this. They are essentially hiding a major advantage their stuff has over their competitors' devices.

@jiska @trusted_device Impressive but for which reason? If you own an android device, buy one of the plenty and good android compatible watches.

@andreclaassen @jiska @trusted_device i presume the same reason that asahi exists: so that people can use apple hardware in their preferred ecosystem

One less thing you purchased a license to use from apple that holds you back in their ecosystem, if you decide to switch.
