## README efitools efitools is a set of tools for manipulating EFI secure boot platforms. If you ever plan to use LockDown.efi (it's an EFI program that installs a predefined set of Secure Boot keys if you run it while your machine is in setup mode) you will want to use your own Secure Boot keys and maybe specify an owner GUID (in hex). The keys should be placed in the SlackBuild directory and named: Platform Key public/private keys - PK.crt, PK.key Key Exchange public/private keys - KEK.crt, KEK.key Signature Database public/private keys - DB.crt, DB.key and the SlackBuild should be executed using: GUID=xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx USE_KEYS=yes \ ./efitools.SlackBuild efitool-mkusb to make a bootable usbstick, the process will delete all files on the usbstick. It's unlikely that you'll use LockDown.efi and there are alternate methods to do what it does, so it's fine just to ignore it. WARNING!!!! PLEASE MAKE SURE YOU KNOW EXACTLY WHAT YOU ARE DOING BEFORE PROCEEDING. SlackBuilds.org 2023 accepts no liability for any issues caused by using this software. The software is provided as is and requires a working knowledge, of setting up secure booting and keys. For information how to use this software for secure/boot on Linux please see the included.
