These keys include the ability to boot from binaries signed by the signing service hosted by Microsoft. This feature includes simultaneous support for two methods of booting under this scheme. Under the first scheme, Fedora will utilize the signing service hosted by Microsoft. Under the second, a site will create their own keys and deploy them in system firmware, and will do their own signing of binaries with it. In both schemes, shim, grub2, and the kernel will detect that they are started in what UEFI describes as "User mode" with Secure Boot enabled, and upon detecting this they will validate the next stage with a Fedora-specific cryptographic public key before starting it. Additionally, grub2 will operate with similar restrictions as it would if you had set a supervisory password in your configuration. Once the kernel is booted, it will also detect tha t it is in Secure Boot mode, which will cause several things to be true: it will validate the boot command line to only allow certain kernel settings, it will check loaded modules for signatures and refuse to load them if they are unsigned, and it will refuse any operations from userland which cause userland-defined DMA." +msgid "The Fedora Secure Boot implementation includes support for two methods of booting under the Secure Boot mechanism.
