If you're Within this position, the passphrase can reduce the attacker from straight away logging into your other servers. This tends to ideally Present you with time to produce and apply a new SSH vital pair and take away access in the compromised key.

Warning: If you have Beforehand produced a important pair, you will be prompted to substantiate that you actually want to overwrite the prevailing crucial:

It is vital to be sure There may createssh be more than enough unpredictable entropy in the system when SSH keys are generated. There happen to be incidents when A huge number of units online have shared the exact same host critical if they ended up improperly configured to crank out The crucial element devoid of right randomness.
