sbctl – Secure Boot key manager

In plain words

sbctl is a command-line tool for managing Secure Boot keys on Linux systems. It allows users to create, enroll, and manage cryptographic keys used in the Secure Boot process, simplifying what would otherwise be complex manual configuration. The tool is designed for Linux administrators and power users who need to maintain custom Secure Boot setups, particularly those using custom kernels or modules. sbctl streamlines key management through an accessible interface.
