HardenVault: Kernel-Userland Secure Secrets

Developers and sysadmins are frustrated that a single userland bug can expose all passwords, SSH keys, and personal secrets, blurring the boundary between kernel and userland. HardenVault provides a hardware-backed, runtime‑protected secrets store that enforces strict isolation, continuously verifies integrity, and prevents privilege escalation, ensuring secrets stay protected even when userland code fails.
