This iOS library wraps calls to the Secure Enclave for key management and data signing.
The example iOS project demonstrates how to use KeyInterface on a blank view to print a public key and sign data. The key names are constantized as kPublicKeyName and kPrivateKeyName in KeyInterface.h. You should change those values to match identifiers for your company and project.
