Employ whitebox cryptography

[TeamSahamati]

Input from Christian Damour, security expert, FIME:

It should be emphasized in security guidelines as very important that :
"separate API keys to be used for SDKs shared with different FIUs."
I fully agree with the above statement and would even advise using one internal storage key per device. To this aim, whitebox cryptography is needed.

Otherwise breaking one set of keys gives access to all APIs / all devices.
