08D7B4

Those are the Check Digits for the notoriously weak double-length key that everyone uses for their test ZMK:

0123456789ABCDEF FEDCBA9876543210

I did a Google search to see if anyone else had posted this number.  Nope.  I own the Weak ZMK Space as of this moment. 

Frankly, the weak key serves a good purpose:  it’s my touchstone to ensure that I’ve not accidentally crossed my test and prod versions of the keys file.  That would be most unfortunate.  As Egon Spengler has duly noted: don’t cross the streams.
