|

<p>
|
|
It has been three months now
|
|
<a href="/about/news#2019-06-12-launch">since we launched</a>
|
|
<span class="brand">keys.openpgp.org</span>.
|
|
We are happy to report:
|
|
It has been a resounding success!
|
|
🥳
|
|
|
|
<h4>Adoption in clients</h4>
|
|
|
|
<p>
|
|
The
|
|
<span class="brand">keys.openpgp.org</span>
|
|
keyserver has been received very well by users,
|
|
and clients are adopting it rapidly.
|
|
It is now used by default in
|
|
<a href="https://gpgtools.org/" target="_blank">GPGTools</a>,
|
|
<a href="https://enigmail.net/" target="_blank">Enigmail</a>,
|
|
<a href="https://www.openkeychain.org/" target="_blank">OpenKeychain</a>,
|
|
<a href="https://github.com/firstlookmedia/gpgsync" target="_blank">GPGSync</a>,
|
|
Debian,
|
|
NixOS,
|
|
and others.
|
|
Many tutorials have also been updated,
|
|
pointing users our way.
|
|
|
|
<p>
|
|
At the time of writing,
|
|
more than 70.000 email addresses
|
|
have been verified.
|
|
|
|

<img src="/assets/img/stats-addresses-2019-09-12.png" style="padding: 1px; border: 1px solid gray;" /><br />
|
|
<span style="font-size: smaller;">If that isn't a promising curve, I don't know what is :)</span>
|
|
</center>
|
|
|
|
<p>
|
|
A special shout-out here goes to GPGTools for macOS.
|
|
They implemented the update process so smoothly,
|
|
the number of verified addresses completely exploded
|
|
when they released their update.
|
|
|
|
<h4>All's good in operations</h4>
|
|
|
|
<p>
|
|
There is not a lot to report operationally,
|
|
and no news is good news in this case!
|
|
Since launch,
|
|
there was nearly zero downtime,
|
|
only a single bug came up
|
|
that briefly caused issues during upload,
|
|
and support volume has been comfortably low.
|
|
|
|
<p>
|
|
Our traffic is currently
|
|
at about ten requests per second
|
|
(more during the day, less on the weekend),
|
|
and we delivered roughly 100.000 mails
|
|
in the last month.
|
|
No sweat.
|
|
|
|
<p>
|
|
We made several small operational improvements
|
|
including deployment of
|
|
<a href="http://dnsviz.net/d/keys.openpgp.org/dnssec/" target="_blank">DNSSEC</a>,
|
|
implementing some
|
|
<a href="/about/api#rate-limiting" target="_blank">rate-limiting</a>,
|
|
nailing down our
|
|
<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP">content security policy</a>
|
|
headers,
|
|
and enabling
|
|
<a href="https://blog.torproject.org/whats-new-tor-0298" target="_blank">single-hop</a>
|
|
mode on our Tor Onion Service.
|
|

<h4>Secure mail delivery with MTA-STS</h4>
|
|
|
|
<p>
|
|
One improvement that deserves special mention is
|
|
<a href="https://www.hardenize.com/blog/mta-sts">MTA-STS</a>,
|
|
which improves the security of outgoing emails.
|
|
|
|
<p>
|
|
While HTTPS is deployed fairly universally these days,
|
|
that sadly isn't the case for email.
|
|
Many servers don't do encryption at all,
|
|
or use a self-signed certificate
|
|
instead of a proper one (e.g. from Let's Encrypt).
|
|
But delivery failures upset customers more
|
|
than reduced security,
|
|
and many mails are still delivered without encryption.
|
|
|
|
<p>
|
|
With MTA-STS, domain operators can indicate
|
|
(via HTTPS)
|
|
that their mail server <em>does</em> support encryption.
|
|
When a secure connection can't be established
|
|
to such a server,
|
|
message delivery will be postponed
|
|
or eventually bounce,
|
|
instead of proceeding insecurely.
|
|
|
|
<p>
|
|
This is extremely useful for service like
|
|
<span class="brand">keys.openpgp.org</span>.
|
|
If encryption isn't reliable,
|
|
attackers can intercept verification mails relatively easily.
|
|
But for providers who have MTA-STS deployed,
|
|
we can be sure that
|
|
every message is delivered securely,
|
|
and to the right server.
|
|
|
|
<p>
|
|
You can <a href="https://aykevl.nl/apps/mta-sts/" target="_blank">run a check</a>
|
|
to find out whether your email provider
|
|
supports MTA-STS.
|
|
If they don't,
|
|
please drop them a message and tell them
|
|
to step up their security game!
|
|
|
|
<h4>Work in progress</h4>
|
|
|
|
<p>
|
|
We are working on two features:
|
|
|
|
<p>
|
|
The first is <strong>localization</strong>.
|
|
Most people do not speak English,
|
|
but so far that is the only language we support.
|
|
To make this service more accessible,
|
|
we are working with the OTF's
|
|
<a href="https://www.opentech.fund/labs/localization-lab/" target="_blank">Localization Lab</a>
|
|
to make the website and outgoing emails
|
|
available in several more languages.
|
|
|
|
<p>
|
|
The second is to bring back
|
|
<strong>third-party signatures</strong>.
|
|
As <a href="/about/faq#third-party-signatures">mentioned in our FAQ</a>,
|
|
we currently don't support these due to spam and potential for abuse.
|
|
The idea is to require
|
|
<a href="https://gitlab.com/openpgp-wg/rfc4880bis/merge_requests/20/diffs" target="_blank">cross-signatures</a>,
|
|
which allow each key to choose for itself
|
|
which signatures from other people it wants to distribute.
|
|
Despite this extra step,
|
|
this is fairly compatible with existing software.
|
|
It also nicely stays out of the way of users
|
|
who don't care about signatures.
|
|
|
|
<p>
|
|
Although work is in progress for both of those features,
|
|
neither have a planned time of release yet.
|
|
|
|
<p>
|
|
Regarding the "<tt>no user ID</tt>" issue with GnuPG
|
|
(mentioned in our
|
|
<a href="/about/news#2019-06-12-launch-challenges">last news post</a>
|
|
and our
|
|
<a href="/about/faq#older-gnupg" target="_blank">FAQ</a>),
|
|
a patch that fixes this problem is now carried by Debian,
|
|
as well as GPGTools for macOS.
|
|
GnuPG upstream has not merged the patch so far.
|
|
|
|
<p>
|
|
That's it!
|
|
Thanks for your interest!

<h4>Why a new keyserver?</h4>
|
|
|
|
<p>
|
|
We created <span class="brand">keys.openpgp.org</span>
|
|
to provide an alternative to the SKS Keyserver pool,
|
|
which is the default in many applications today.
|
|
This distributed network of keyservers has been struggling with
|
|
<a target="_blank" href="https://medium.com/@mdrahony/are-sks-keyservers-safe-do-we-need-them-7056b495101c">abuse</a>,
|
|
<a target="_blank" href="https://en.wikipedia.org/wiki/Key_server_(cryptographic)#Problems_with_keyservers">performance</a>,
|
|
as well as <a href="http://www.openwall.com/lists/oss-security/2017/12/10/1">privacy issues</a>,
|
|
and more recently also
|
|
<a target="_blank" href="http://nongnu.13855.n7.nabble.com/SKS-apocalypse-mitigation-td228252.html">GDPR</a>
|
|
compliance questions.
|
|
Kristian Fiskerstrand has done a stellar job maintaining the pool for
|
|
<a target="_blank" href="https://blog.sumptuouscapital.com/2016/12/10-year-anniversary-for-sks-keyservers-net/">more than ten years</a>,
|
|
but at this point development activity seems to have
|
|
<a target="_blank" href="https://bitbucket.org/skskeyserver/sks-keyserver/pull-requests/60/clean-build-with-405">mostly ceased</a>.
|
|
|
|
<p>
|
|
We thought it time to consider a fresh approach to solve these problems.
|
|
|
|
<h4>Identity and non-identity information</h4>
|
|
|
|
<p>
|
|
The <span class="brand">keys.openpgp.org</span> keyserver splits up
|
|
identity and non-identity information in keys.
|
|
You can find more details on our <a href="/about" target="_blank">about page</a>:
|
|
The gist is that non-identity information (keys, revocations, and so on)
|
|
is freely distributed,
|
|
while identity information
|
|
is only distributed with consent
|
|
that can also be revoked at any time.
|
|
|
|
<p>
|
|
If a new key is verified for some email address,
|
|
it will replace the previous one.
|
|
This way,
|
|
every email address is only associated with a single key at most.
|
|
It can also be removed from the listing
|
|
at any time by the owner of the address.
|
|
This is very useful for key discovery:
|
|
if a search by email address returns a key,
|
|
it means this is the single key
|
|
that is currently valid for the searched email address.
|
|
|
|
<h4>Support in Enigmail and OpenKeychain</h4>
|
|
|
|
<p>
|
|
The <span class="brand">keys.openpgp.org</span> keysever
|
|
will receive first-party support in upcoming releases of
|
|
<a href="https://enigmail.net" target="_blank">Enigmail</a> for Thunderbird,
|
|
as well as
|
|
<a href="https://play.google.com/store/apps/details?id=org.sufficientlysecure.keychain&hl=en">OpenKeychain</a> on Android.
|
|
This means users of those implementations will
|
|
benefit from the faster response times,
|
|
and improved key discovery by email address.
|
|
We hope that this will also give us some momentum
|
|
to build this project into a bigger community effort.
|
|
|
|
<h4 id="2019-06-12-launch-challenges">Current challenges</h4>
|
|
|
|
<p>
|
|
Privacy-preserving techniques in keyservers are still new,
|
|
and sadly there are still a few compatibility issues
|
|
caused by splitting out identity information.
|
|
|
|
<p>
|
|
In particular, when GnuPG (as of this writing, version 2.2.16) encounters
|
|
an OpenPGP key without identities,
|
|
it throws an error "no user ID"
|
|
and does not process new non-identity information
|
|
(like revocation certificates)
|
|
even if it is cryptographically valid.
|
|
We are actively engaged in
|
|
providing fixes for these issues.
|
|
|
|
<h4>The future</h4>
|
|
|
|
<p>
|
|
Privacy-preserving techniques in keyservers are still new,
|
|
and we have more ideas for reducing the metadata.
|
|
But for now, our plan is only to
|
|
keep <span class="brand">keys.openpgp.org</span> reliable and fast 🐇,
|
|
fix any upcoming bugs 🐞,
|
|
and <a href="/about#community">listen to feedback</a> from the community. 👂
