This is the secret key file?

I think it must be an important file. If you check the filename it's "maybe" the container file for FeC codes (like in RMC where FSC are stored in Container too).
If you reverse the fec binary in IDA you can found some FeC related functions to handle FeC requests....

Currently I have only 2 fec container files from 2 different devices. One is empty (contains only 4 bytes header) and other has some data inside.
Next days. I will try to get more container files to check them....
I don't know (but I hope) if I'm on the right way....
