Trying to get PKA working

[Philip Colmer]

Hello all

I'm using gpg 2.2.19:

$ gpg --version
gpg (GnuPG) 2.2.19

I've followed the instructions I found at
https://gushi.org/make-dns-cert/HOWTO.html to publish a public key via
a TXT record in DNS but, when I get to the testing step of:

echo "foo" | gpg --no-default-keyring --keyring /tmp/gpg-$$ --encrypt
--armor --auto-key-locate pka -r you at you.com

(where you at you.com is the address to be tested) then I get:

error retrieving '<email address>' via PKA: No name

I've tried testing it against the author's details
(danm at prime.gushi.org) but I get the same "No name" error.

There wasn't a configuration file in place for gpg so I created one
with just this entry:

auto-key-locate pka

Should there be other entries in that file? Is that why I'm getting
the "No name error"?

Thank you.

Regards

Philip
