Well, sort of.

Mine is a bit more complicated because it also works around the
protocol error in RFC 2440 related to V4 key expiration (V4 key
expiration time is not covered by certificates because it is only
contained in the self signature, not in the key material, in contrast
to V3 keys): If the key to be signed is a V4 key with an expiration
time set, a V4 signature is made which expires at that time, too (or
even earlier).
