Oh I read now that it’s only to verify and so they mainly exchange a symmetric crucial, and the general public important encrypts the symmetric crucial so the non-public crucial can decrypt it.
Components Protection Modules (HSMs) supply an additional layer of stability for SSH keys by holding personal keys stored in tamper-resistant hardware. Rather than storing non-public keys in the file, HSMs retail store them securely, blocking unauthorized accessibility.
If you decide on to overwrite The real key on disk, you will not manage to authenticate createssh using the earlier important any more. Picking “yes” is really an irreversible destructive system.
