ARCHIVE - Prior Versions of DBX files

These files are the older archived version that were used to update the Secure Boot Forbidden Signature Database, dbx. It contains the raw bytes passed in *Data to SetVariable()... an EFI_VARIABLE_AUTHENTICATION_2 concatenated with the new variable value. Example usage: SetVariable( "dbx", EFI_IMAGE_SECURITY_DATABASE_GUID, NV+BS+RT+AT+AppendWrite, dbxUpdateDotBin_sizeInBytes, *dbxUpdateDotBin_bytes). dbxupdate.bin already contains a Microsoft KEK signature (encoded as specified by the UEFI spec).
