$ gpg --dump-options |grep session
The simplest way would be something like this:
$ gpg --show-session-key -o foo.txt foo.gpg 2>&1 \
| gpg -e -r key-escrow at privacy.gov | mail solo at u.n.c.l.e
And on the u.n.c.l.e site Napoleon could do this:
$ gpg --override-session-key extracted_from_mail msg_from_echelon
Well you can also use the session key to create a public key encrypted
packet and prepend it to the message - however there is no direct
support for it in GnuPG.
