The Revoke HID Key(s) tool, allows the loading of a Key Revocation list.

need to revoke a specific HID key(s), a request to HID is made and a Key Revocation List is created,
and delivered to the customer.
See iCLASS CP400 and CP575 Key Duplication using Seeds Application Note (PLT-01416) for detail

Note: Once HID Keys have been revoked, they are not allowed to be reinstalled on the device.
