quartus_sign fails to generate signed ccert

Hi @Farabi , I was able to get help from Intel via our FAE. Basically the answer was the permission settings (should have been 0x40) which are part of the "Security Methodology for Intel FPGAs and Structured ASICs User Guide". However, this document is restricted. But for others reading this post, the correct settings were actually part of the " Intel Agilex® 7 Device Security User Guide", Page 33.

I will close this case. Thank you.
