Description

Kernel images can be generated and signed for UEFI Secure Boot workflows. This is useful for administrators who maintain custom kernels while keeping Secure Boot verification enabled.

It is a command-line Secure Boot tool built from development source. Signing keys and boot images are security-critical; mistakes can prevent booting or weaken trust, so users should keep recovery media and protect private keys.
