Components Stability Modules (HSMs) offer an extra layer of safety for SSH keys by maintaining private keys saved in tamper-resistant hardware. Instead of storing non-public keys within a file, HSMs retailer them securely, avoiding unauthorized access.
Then it asks to enter a passphrase. The passphrase is used for encrypting The important thing, making sure that it cannot be utilised even though another person obtains the private important file.
