A tutorial demonstrates how to store SSH private keys in a TPM chip for enhanced security, preventing key extraction by malware and eliminating filesystem storage. The method leverages built-in TPM hardware available on most modern machines, providing hardware-level protection comparable to dedicated HSMs. This approach adds physical security layers like touch requirements while maintaining SSH functionality.
Background
TPM (Trusted Platform Module) chips are hardware security components built into modern computers, commonly used for secure boot processes and cryptographic operations. SSH keys are traditionally stored as files on disk or in memory, making them vulnerable to extraction.
