If the encryption key programming file and the encrypted configuration file are generated in different versions of the Quartus II software, will the design security feature still function?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description Yes, if the encryption key programming (.ekp) file and the encrypted configuration file are generated in different versions of the Quartus® II software, the design security feature will still function correctly as long as the encrypted configuration files are generated with the same key. A device programmed with that key will configure successfully with the encrypted configuration file, regardless of the Quartus II software used to generate these files.
