I have another question about key expirations. Suppose I have a key
that was originally created without an expiration, and I distribute
that key. Later, I add an expiration date to the original key. Does
the new expiration have any effect if someone has my key without the
expiration? In other words, is the expiration date considered a
discretionary control or a mandatory control?
