Is there a way to force an expiration date when encrypting a

for additional security. I have a friend who is inquiring. I've
already informed him of the "for his/her eyes only" option.
What is that option?
--for-your-eyes-only
But don't think it adds real security. In OpenPGP, the FYEO option
just sets a flag in the message that means (in effect), "Pretty
please, with sugar on top, treat this as for your eyes only". The
recipient is free to ignore the flag and do whatever they like.
Is that analagous to the flag in older versions of PGP that would
cause a message to be displayed in a non-printable/non-copyable
format?
It is more than analogous - it is that exact flag. Even in old PGP,
the flag was really just advisory.
