  24       <div class="date">10th September 2014</div>
  25       <div class="body"><p>Yesterday, I had the pleasure of attending a talk with the
  26 <a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
  27 <a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
  28 OpenPGP keyserver pool sks-keyservers.net</a>, and was very happy to
  29 learn that there is a large set of publicly available key servers to
  30 use when looking for peoples public key.  So far I have used
  31 subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
  32 were misbehaving, but those days are ended.  The servers I have used
  33 up until yesterday have been slow and some times unavailable.  I hope
  34 those problems are gone now.</p>
  35
  36 <p>Behind the round robin DNS entry of the
  37 <a href="https://sks-keyservers.net/">sks-keyservers.net</a> service
  38 there is a pool of more than 100 keyservers which are checked every
  39 day to ensure they are well connected and up to date.  It must be
  40 better than what I have used so far. :)</p>
  41
  42 <p>Yesterdays speaker told me that the service is the default
  43 keyserver provided by the default configuration in GnuPG, but this do
  44 not seem to be used in Debian.  Perhaps it should?</p>
  45
  46 <p>Anyway, I've updated my ~/.gnupg/options file to now include this
  47 line:</p>
  48
  49 <p><blockquote><pre>
  50 keyserver pool.sks-keyservers.net
  51 </pre></blockquote></p>
  52
  53 <p>With GnuPG version 2 one can also locate the keyserver using SRV
  54 entries in DNS.  Just for fun, I did just that at work, so now every
  55 user of GnuPG at the University of Oslo should find a OpenGPG
  56 keyserver automatically should their need it:</p>
  57
  58 <p><blockquote><pre>
  59 % host -t srv _pgpkey-http._tcp.uio.no
  60 _pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
  61 %
  62 </pre></blockquote></p>
  63
  64 <p>Now if only
  65 <a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
  66 HKP lookup protocol</a> supported finding signature paths, I would be
  67 very happy.  It can look up a given key or search for a user ID, but I
  68 normally do not want that, but to find a trust path from my key to
  69 another key.  Given a user ID or key ID, I would like to find (and
  70 download) the keys representing a signature path from my key to the
  71 key in question, to be able to get a trust path between the two keys.
  72 This is as far as I can tell not possible today.  Perhaps something
  73 for a future version of the protocol?</p>
