If you decide on to overwrite The main element on disk, you will not manage to authenticate using the preceding crucial any more. Be quite cautious when picking Sure, as it is a destructive system that can't be reversed.
Hardware Stability Modules (HSMs) provide an extra layer of security for SSH keys by maintaining non-public keys saved in tamper-resistant hardware. As an alternative to storing non-public keys inside of a file, HSMs retail store them securely, preventing unauthorized access.
Prior to completing the ways With this segment, make sure that you possibly have SSH key-centered authentication configured for the foundation account on this server, or if possible, that you've SSH vital-based authentication configured for an account on this server with sudo entry.
