I'm trying to import custom secure boot keys, as to use opencore with secure boot (more of a personal challenge than anything), and I noticed an option in bios to do so. I already have the pk, kek, and db in .auth format, but it seems the bios only accepts them as .bin (tried keytool, though it just spat out a security violation error)?
Question is, how would I go around getting custom keys into the bios?
