Using the Design Security Features with OpenCL Compiler

I am not familiar with HDL and Quartus and I am using OpenCL for Arria 10 device. How can I encrypt the bitstream with .aocx files? I have found out that .aocx file contains the top.rbf file content...

I have also discovered that programming key into device kills any interaction with OpenCL. When I start my application, I get the error "PCIe-to-fabric read test failed", OpenCL API cannot get device_id, etc. And even aocl diagnose doesn't work with the same error. Since I don't know how to clear the key, I have to reboot my PC to fix this problem.

Am I able to use device security features with OpenCL at all?

UPD: Also it seems that .rbf file encrypted with using the .qlk file (which is made from base.sof file) does not work causing the error "CL_INVALID_BINARY" when I insert it into the .aocx file.
