If you look at the Registration Phase section it shows that cryptographicEntry is basically the following and the flowchart show the steps

   “iv”: “cjwe7Q/ZSUIzf64MOKvJbA==”, 
   “dek”:       “iULqm0Cv5vj6yxBQQuHkoOPoNVcxXTiLm2vPWpbaA86VW8Q4rTuCyUs9KU+cJdDs”,  “salt”: “ksSva39weXQdRMQhHQ17BwCJa0s1yBH”, 
“kekIV”: “Oss1I1eOFZuc6mQ33ssWSA==”,
