Apparently, there was a security reason serious enough to change the production of all A12 and A13 devices in the fall of 2020. Also, TIL, the secure enclave in iPhones *does not* include key storage 🤯 So many questions! https://support.apple.com/... https://twitter.com/...

Apple Support docs show that unusual mid-production hardware changes were made to its A12, A13, and S5 chips last fall, to update the Secure Storage Component
@T_Morris_Wealth @MacRumors @HartleyCharlton Their architecture of storing private keys *outside* the secure perimeter seems highly unorthodox. It is this storage part that they had to upgrade, but I'm not sure there's a way to secure it outside of the SE. https://twitter.com/...
