<div dir="ltr"><div>Hello,<br><br></div>I like Jiri's idea. Why not deliver the distribution without a certificate but add documentation and tooling (scripts or code) to easily install a certificate from <a href="http://letsencrypt.org">letsencrypt.org</a>? It's the cleanest solution since it will avoid bundling a self-signed certificate. The main issue I have with self-signed certificates is that users will most likely not change it, which is a bigger issue than using unsecured connections.<br><br><br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr">Thank you,<br>Stefan Negrea<br><br>Software Engineer<br></div></div></div>

</span>Cool ! That would work for the local agent, which is the scenario I was<br>
planning on working on. For remote agents, we should *not* do this, as<br>
the keystore includes the private key for the cert, which should be<br>
known only to the server. But for the remote agent, I expect the server<br>
to use a proper certificate chain.<br>

</span>That's good to know, thanks!<br>

> I do not know how to tell WildFly in its security-realm to do this same kind of bypass... did you look into that? Because the agent will need to be told about doing this bypass, too. The way I worked around it was I actually put my self-signed cert into my JVM's truststore (which isn't something I think we want to ask people to do).<br>
<br>
</span>It depends on the HTTP client you are using. In the "production"<br>
scenarios, no change is needed, as the cert would probably have a valid<br>
chain.<br>
<br>
For dev scenarios, or scenarios where the cert is issued by an unknown<br>
root CA (like internal certificates), the common practice is to add the<br>
root CA to the JVM's keystore, similar to what you did. The reason is<br>
that this cert is not trusted by any known Certificate Authority, so, an<br>
admin would have to explicitly tell that this cert is known and is to be<br>
trusted. The cert we will be shipping on the keystore is *not* trusted<br>
and is intended to be used only on dev scenarios.<br>
<br>
Another practice is to do a certificate pinning, ie, tell your HTTP<br>
client that you know about this specific cert. The disadvantage of this<br>
is that we'd have to keep the server and client in sync. Looking at your<br>
instructions on secure-comm.html , this is probably what you are doing<br>
on the agent side.<br>
<br>
Unfortunately, there's no secure solution that I know of that would<br>
allow us to ship something usable for our production distribution.<br>
<br>
There was a thread some time ago on wildfly-dev about auto generating<br>
certificates on the first boot. I believe this was part of Elytron and<br>
we might be able to benefit from this in the future.<br>
