Using signing in a group environment
Wed May 16 18:56:01 2001
I would like to create a secret key for our group here at work so that
we can send out signed email. What would be the best way of doing this
so that when a group member leaves, they would not be able to continue
to send signed email? If a member should leave, would the secret key
have to be expired or is there a better way? If the signing key was
expired, how would this effect any older signed messages?
