VhlCfg / File / LegicKeyList Value
This is a list of keys required for accessing LEGIC data
segments that are encrypted with a user-defined key.
The keys are transferred into the persistent key storage
of the LEGIC SM on the first reboot after configuration
has been loaded. The configuration value is deleted
afterward.
The encryption keys are used by
LegicUserKeyIndexList.
