What happens if my key is lost ?..

Answer / ramkumar

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. The CA (see Question 4.1.3.12) must be notified
immediately so that the key can be revoked and placed on a
certificate revocation list (see Question 4.1.3.16) to
prevent any illegitimate use if the key is found or
recovered by an adversary. Loss of a private key 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 should also obtain a new key right away to
minimize the number of messages people send you that are
encrypted under your old key, since these can no longer be
read.
