How to develop a remote key injection system

• Please download the demo and doc here
• In our demo, we use demo certificates, so please download the initialize certificate APK and run it to initialize the owner certificate and the key loader certificate.

 Please notice this step will replace the owner of the terminal, when you ends the test phase, and want to apply your own owner certificate, all the test 
 certificates should be clear, the clear process will need us to approve, so it will generate a token file in an inserted TF card, send us the token file, 
 after we signed, we will return you a .sig file, after you verify in the terminal, then the certificates will be removed. Then you can install your owner 
 again.
