Bugzilla Bug 26970

gpg-agent works like ssh-agent ... when you run it, it will output an
environment variable + pid allowing you to 'hook in' to the current gpg-agent
process ...

it would be nice if all your new terminals had access to the gpg-agent so that
you dont have to launch a new one and all that fun stuff

here is the hack i made real quick (i'd highly suggest a rework of keychain into
modular functions so that it could easily support more agents/conf files in the
future)
# hook into gpg-agent
running="$(ps ax | grep 'gpg-agent --daemon' | grep -v grep | awk '{print $1}')"
if [ -z "${running}" ] ; then
    echo $E " ${GREEN}*${OFF} Starting new gpg-agent"
    gpg-agent --daemon > ~/.gpg-agent
else
    echo $E " ${GREEN}*${OFF} Found existing gpg-agent at PID ${running}"
fi

supporting quintuple-agent would be nice too. It works the same way as
ssh-agent and gpg-agent but will need a --fork option instead of --daemon.

As far as I know gpg-agent is included in the unstable versions of gpg (eg.
1.95). But it doesn't work with the stable gpg 1.2.4. gpg-agent is apperently

As far as I know gpg-agent is included in the unstable versions of gpg (eg.
1.95). But it doesn't work with the stable gpg 1.2.4. gpg-agent is apperently
something they got from the Ægyption project. Anyway this is really
suboptimal, so instead I suggest we use the gnome-gpg agent. This works with
the gnome-keyring deamon and has a nice gnome interface :)

I've created an ebuild for the gnome-gpg 0.3.0:
http://www.cs.auc.dk/~arj/gnome-gpg-0.3.0.ebuild

not knowing this bug existed, i hacked up a quick script for gpg-agent

nothing even close to complete... but a basic idea is here:

just mentioned this to agriffis and it seems we might see some of the gpg-agent stuff in the near future.

First pass at gpg-agent support is now in keychain-2.4.0
