Design Security Features Stratix IV issue (Terasic DE4 board)

I trying to use volatile Key Design Security Features on StratixIV divice on Terasic DE4 board. 

 

For this i need to encrypt my design and put it into flash on board. 

 

In Quartus it's possible to encrypt .sof file into .pof (and some other formats, but not .flash). 

doc: http://www.altera.com/literature/an/an556.pdf 

 

But in Terasic documents showed only tutorial for programming board with *.flash files. 

(In that tutorial .sof converts into .flash via "Nios II EDS command shell" command sof2flash.) 

 

way to solve: 

 

I don't know how convert and encrypt my .sof into .flash 

OR 

I don't know how programm DE4 board by encrypted in Quartus .pof file 

 

How can I solve this situation? 

 

Terasic support didn't give solution yet. 

 

Help me Engineers, you're my only hope.

Were you able to figure out how to program your .pof file?
