Without rooting an image, is there a way to test if AKS is hardware
backed? KeyChain.isKeyAlgorithmSupported("RSA")) returns true, but others
suspect the generation times are too fast (1.2-1.7 seconds).
On Kitkat Nexus 5, I see /system/lib/hw contains 2 keymaster
implementations:
keystore.default.so
keystore.msm8974.so
I initially was going to look at the memmap of keystored to see what was
loaded. Any comments, much appreciated.
Thanks.
