Question 119. What Happens if I Lose my Private Key?

If your private key is lost or destroyed, but not compromised, you can no longer sign or decrypt messages, but anything previously signed with the lost key is still valid. This can happen, for example, if you lose the smart card used to store your key, or if the disk on which the key is stored is damaged. You need to obtain a new key right away, to minimize the number of messages people send you that are encrypted under your old key, messages which you can no longer read.
