- tokenizerrr 11y agoThat would only happen if you do not know your key has been leaked. If you know the "laptop key", as this article calls it, has been leaked you revoke it immediately and do not use it anymore. It being revoked should mean that other people (whose clients download the revocation list) will not be signing new communications with your compromised key anymore.
