A practical tutorial on storing SSH private keys in TPM (Trusted Platform Module) chips rather than on the filesystem. The guide compares TPM security against traditional HSMs (like Yubikey and Nitrokey), explains TPM's device-bound nature, and provides step-by-step Linux configuration using tpm2-tools.
