| To protect the private key, it should be generated locally on a user's machine (e.g. using [[ui_puttygen|PuTTYgen]]) and stored encrypted by a passphrase. The passphrase should be long enough (that's why it's called passphrase, not password) to withstand a [[wp>Brute-force_attack|brute-force attack]] for a reasonably long time, in case an attacker obtains the private key file. | To protect the private key, it should be generated locally on a user's machine (e.g. using [[ui_puttygen|PuTTYgen]]) and stored encrypted by a passphrase.
