8.4.2.6 Encryption Keys Tab
CYCLONE FX programmers and CYCLONE programmers with the ProCryption Security
Activation License are able to encrypt programming images with a user-generated ImageKey. In
order to load an encrypted image onto a Cyclone, or to program with an encrypted image once it is
on the Cyclone, the ImageKey used to encrypt that image must be present on the Cyclone.
The Encryption Keys tab displays any ImageKeys that reside on the Cyclone. The Name and
unique ID number for each ImageKey is shown.

The Add Encryption Key button allows the user to browse to an ImageKey that they wish to add to
the Cyclone. Encrypted (eSAP) programming images cannot be loaded onto the Cyclone unless
the ImageKey that was used to encrypt them is present on the Cyclone.
The Delete Encryption Key button will delete the selected ImageKey from the Cyclone. The user
should bear in mind that if the ImageKey is missing for an eSAP image, that image will be locked
and cannot be programmed.
