It's all right, just *really* inefficient. I've been online for a
while now and had this email address for much of that time, I receive
a lot of email and if there isn't an existing rule for an address then
it'll end up in one of several catchalls (depending on which address
was used mainly). I'll see those emails eventually, but it was pure
luck that I saw yours the same month as it was sent ... let alone the

By default GPGME will use the same configuration and keyring/keybox of
the user invoking the code. That can be changed to a custom or
alternative configuration or homedir location, but it is a little
fiddly. Mind you, so is doing that on the command line.

Fair enough. HKP and HKPS are just slightly modified HTTP and HTTPS
anyway (well, actually they haven't modified those protocols, they
just define that what's running on them is a keyserver and then define
I used to do something similar when directing certain key retrievals
through tor (before it was supported natively), but now I can't recall
where I left that script. Oh well.

Which is excellent to hear.

For relative values of good. It's okay for quick and dirty if the
only people accessing the script already have shell access, but
otherwise it's been known to have issues. It also has a very limited
subset of GPG features and sometimes for rather surprising reasons.

Hmm, I suspect that most use of list-packets or pgpdump on an
encrypted message is to check the number and key IDs a message is
encrypted to prior to attempting decryption and so there's probably a
decent enough case for adding that to GPGME. Probably the ciphers and
algorithms used too.
The other lacking item is support for groups from the gpg.conf. I've
got a work around for that, but it's not ideal (and it's also not
online yet, I want to give it some basic testing first).
