Introducing: Nitrux SB Manager
We’re excited to announce the release of Nitrux SB Manager, a streamlined utility designed to simplify Secure Boot management on Nitrux. With this utility, users can effortlessly generate Machine Owner Keys (MOK), sign kernels for Secure Boot, and enroll keys directly into the UEFI firmware.
A Machine Owner Key (MOK) is a cryptographic key pair used in the Secure Boot framework to authenticate and verify the integrity of boot-related software, such as the Linux kernel and kernel modules.
The MOK allows users to create and manage their keys for signing software, enabling them to add custom kernels or modules to a Secure Boot-enabled system without deactivating it.
Secure Boot is a security standard developed by the Unified Extensible Firmware Interface (UEFI) Forum to protect systems from malicious software that attempts to load during the boot process. When Secure Boot is enabled, the firmware checks the digital signature of each piece of boot software—such as bootloaders, operating systems, and kernel modules—against a trusted certificate store. Only software with a valid signature can execute, preventing unauthorized or malicious code from running.
It protects your system from malicious software by ensuring only signed and trusted code runs at startup. Sounds great in theory, right? However, in practice, Secure Boot often feels like a brick wall for those who want to use Linux.
