+"""Encryption keys used by FreeStyle Libre 2 glucometers.

+The following constants are key materials required to communicate with the FreeStyle
+Libre 2 glucometers.
+
+No copyright is claimed for these keys, as they are requisite constants that are part
+of the device's communication protocol.
+
+We assert these these keys do not constitute Technical Protection Measures for the
+purpose of copyright protection, as they do not protect copyrighted material but
+rather obfuscate the communication between two devices under the control of the user.
