Encryption
==========

* If encryption_version==0 then return data without encryption
* The keys should be unique for each device
To add a new encryption_version:
1) Code your new encryption_version
2) Update the last encryption_version available in webserve.py
3) Remember to maintain old encryption versions and key generators for retrocompatibility
