Oh, yes, you are right. After all, if the attacker can "steal" a signature, then each time we try to sign something legitimate, the attacker may be able to hijack it and sign something we don't want to sign, and the thing we want so sign will remain unsigned. And even if the attacker can't hijack the signature, malware may very well hijack the email account, etc. > The idea might be good for damage mitigation; but for permitting > continued normal operation, it's IMO a non-starter on every level. Yes, compromised machine must be cleaned ASAP. BTW, if somebody is willing to develope such safety device, I hope it is designed to have a "go ahead" button to press, but not to require entering a pin-code each time. If entering the password to unlock GPG key too often is unpleasant, doing that in a tiny pin-pad that maybe is not in a comfortable place would be unusable.
