How can I configure the second stage boot loader image for the correct authentication signing key type?

You must select the appropriate security settings for authentication before generating the second-stage boot loader in the Intel® Arria® 10 SoC FPGA Authentication Signing Utility. After the settings are applied, you build the boot loader and the configurations are incorporated in the image. After these steps, you must build and sign the boot loader.

If you use the GIT repo to build the boot loader source, then you must build the image and then use alt_authtool.py to sign the final image.
