Plugin: UEFI PK
Introduction
The platform key (PK) specifies the machine owner, typically the OEM that created the laptop or desktop.
Several device manufacturers decide to ship the default “AMI Test PK” platform key instead of a Device Manufacturer specific one. This will cause an HSI-1 failure.
GUID Generation
These devices use the GUID constructed of the uppercase SHA256 of the X.509 certificate. e.g.
UEFI\CRT_{sha256}
Additionally, the subject vendor and name are used if provided.
UEFI\VENDOR_{vendor}&NAME_{name}
These GUIDs can be used to fulfill “other device” requirements when installing KEK
updates.
External Interface Access
This plugin requires:
- read access to
/sys/firmware/efi/efivars
