This implementation does not provide any security guaranties.
* The input method (NotSoSecureInput) runs a crypto protocols that is
sufficiently secure IFF the end point is implemented on a trustworthy

service itself this implementation is not secure.
* This implementation provides most of the functionality, but not the
secure UI infrastructure required to run Android Protected
Confirmation.
