Query ref Omnikey Keys

I've been working on a solution for my employer that is required to integrate with iClass cards that have a secure site\facility code and card identified stored in their Wiegand data.

As far as my understanding goes, the only way I could access these is via secure mode.  I have been successful in connecting to the cards and reading the Wiegand data.  I can decode it successfully and my work are pleased.

As part of this work, I've had to use some keys that I do not seem to be able to find in the public domain.

Can someone please advise me what these keys may be (i.e. what are they called).  From the purposes of the documentation I would describe them as the Kcur key.

The keys are:

A59615xx{snipped}xx73
233C47xx{snipped}xxDD
B497CAxx{snipped}xx28

Any advice would be appreciated.

Re: Query ref Omnikey Keys

if you have site\facility code （where you get it？）and card Number （which are printed on card）， you can calculate the Wiegand data with some special keys
