Zion Key Management API

ZKMA (Zion Key Management API) is a library which provides a way for developers to manage seed security built into HTC EXODUS devices, which integrates Zion protection. All secure operations (input pin, display seed, sign transaction…) will be performed by the trusted OS and no secure data exposed to the rest of Android.
