Configure the keyring used by GPG Mail?

I would like to temporarily use an alternative keyring for encrypting / signing email.
I tried to set GNUPGHOME on the commandline, then launch from there (which works for GPG -- but that didn't work. It continued using the default keyring in ~/.gnupg/.

    Hi Jonathan,

    that will unfortunately not work, since itself can't communicate with the gpg binary, but instead a separate XPC takes care of that, which is launched on demand, so it's not easily possible to set environment variables for that XPC.

    What you could try is to temporarily symlink the new GNUPGHOME to ~/.gnupg.

    Hope that helps.

    Okay, I'll try that.
    I was a bit hesitant to mess with the ~/.gnupg as there are various open sockets from different processes there, etc.

    That should not be a big problem.
    Just make sure to always create a backup of ~/.gnupg before switching it with a symlink and to stop all gpg related processes:

    killall gpg-agent
    killall gpg
    killall dirmngr
    killall scdaemon

    and applications that might be using it, e.g. GPG Keychain, Mail, org.gpgtools.Libmacgpg.xpc (use ps aux | grep -I libmacgpg\.xpc to find its pid). If you do that, no important data should be corrupted.

    Great to hear that.

    Sorry there's no easier way to do this.
