<h1>FAQ</h1>
|
||||
<p class="lead">Do I have to pay to use this service?</p>
|
||||
<p>No, it's free.</p>
|
||||
<p class="lead">Can I use this certificate on my commerce website?</p>
|
||||
<p>Although there's no technical reason why you couldn't use
|
||||
the sslip.io SSL key and certificate for your commerce
|
||||
web, we <i>strongly</i> recommend against it: the key
|
||||
is publicly available; your traffic isn't secure. sslip.io's
|
||||
primary purpose is to assist developers who need to test
|
||||
against valid SSL certs, not to safeguard content.</p>
|
||||
<p class="lead">My webserver wants a certificate and an "intermediate certificate
|
||||
chain"—where do I get that? </p>
|
||||
<p>Certain web servers (e.g. <a href="http://www.tenable.com">Tenable's</a> <a href="http://www.tenable.com/products/nessus-vulnerability-scanner">Nessus</a> scanner) prefer to split the chained certificate file
|
||||
(which has three concatenated certificates) into two
|
||||
files: one file containing a single certificate for the
|
||||
server itself (e.g. the "*.sslip.io" certificate), and
|
||||
a second file containing the intermediate certificate
|
||||
authorities (e.g. the two COMODO certificate authorities).</p>
|
||||
<p>You can split the chained certificate file by hand, or
|
||||
you can download them, pre-split, from GitHub: </p>
|
||||
<ul>
|
||||
<li>the server <a href="https://raw.githubusercontent.com/cunnie/sslip.io/master/ssl/sslip.io.crt.pem">certificate</a> ("*.sslip.io") </li>
|
||||
<li>the intermediate certificate <a href="https://raw.githubusercontent.com/cunnie/sslip.io/master/ssl/intermediate-ca.crt.pem">chain</a> (the COMODO CAs)</li>
|
||||
</ul>
|
||||
<p class="lead">Why can't I use dots in my hostname? xip.io lets me use
|
||||
dots. </p>
|
||||
<p>You can't have dots, but you can have dashes: for example,
|
||||
"www-sf-ca-us-10-9-9-142.sslip.io" will work with sslip.io's
|
||||
wildcard SSL certificate, but "www.sf.ca.us.10.9.9.142.sslip.io"
|
||||
will not. This is a technical limitation of wildcard
|
||||
certs and the manner in which browsers treat them (read
|
||||
more <a href="http://security.stackexchange.com/questions/10538/what-certificates-are-needed-for-multi-level-subdomains">here</a>).</p>
|
||||
<p>This restricts sslip.io's usage model. For example, it
|
||||
won't work properly with Cloud Foundry's app domain or
|
||||
system domain.</p>
|
||||
<p class="lead">Does sslip.io work with name-based virtual hosting? We
|
||||
have multiple projects but only one webserver.</p>
|
||||
|
||||
<p> sslip.io interoperates quite well with <a href="https://en.wikipedia.org/wiki/Virtual_hosting#Name-based">name-based virtual hosting</a>.
|
||||
You can prepend identifying information to the sslip.io
|
||||
hostname without jeopardizing the address resolution, and then use
|
||||
those hostnames to distinguish the content being served.
|
||||
For example, let's assume that your webserver's IP address
|
||||
is 10.9.9.30, and that you have three projects you're
|
||||
working on (Apple, Google, and Facebook). You would use
|
||||
the following three sslip.io hostnames: </p>
|
||||
|
||||
<ul>
|
||||
<li>apple-10-9-9-30.sslip.io</li>
|
||||
<li>facebook-10-9-9-30.sslip.io</li>
|
||||
<li>google-10-9-9-30.sslip.io</li>
|
||||
</ul>
|
||||
<p class="lead">Can you make the hostnames easier to remember? It's as
|
||||
hard as memorizing IP addresses.</p>
|
||||
<p>Unfortunately, no. We appreciate that "52-0-56-137.sslip.io"
|
||||
is not an easy-to-remember hostname, whereas something
|
||||
along the lines of "aws-server.sslip.io" would be much
|
||||
simpler, but we don't see an easy solution—we need
|
||||
to be able to extract the IP address from the hostname
|
||||
in order for our DNS nameserver to reply with the proper
|
||||
address when queried.</p>
|
||||
<p class="lead">Do you have support for IPv6-style addresses?</p>
|
||||
<p>Not yet, but if there's enough demand for it we might try
|
||||
implementing it.</p>
|
||||
<p class="lead">Why did you choose a 4096-bit key instead of a 2048-bit
|
||||
key?
|
||||
</p>
|
||||
<p>We couldn't help ourselves—when it comes to keys,
|
||||
longer is better. In retrospect there were flaws in our
|
||||
thinking: certain hardware devices, e.g. YubiKeys, only
|
||||
support keys of length 2048 bits or less. Also, there
|
||||
was no technical value in making a long key—it's
|
||||
publicly available on GitHub, so a zero-bit key would
|
||||
have been equally secure.</p>
|
||||
<p class="lead">Do I have to use the sslip.io domain? I'd rather have a
|
||||
valid cert for my domain.</p>
|
||||
<p>If you want valid SSL certificate, and you don't want to
|
||||
use the sslip.io domain, then you'll need to purchase
|
||||
a certificate for your domain. We purchased ours from
|
||||
<a href="https://www.cheapsslshop.com">Cheap SSL Shop</a>,
|
||||
but use a vendor with whom you're comfortable. </p>
|
||||
<p class="lead">What is the sslip.io certificate chain? </p>
|
||||
<p>The sslip.io certificate chain is the series of certificates,
|
||||
each signing the next, with a root certificate at the
|
||||
top. It looks like the following:</p>
|
||||
<div class="col-sm-12">
|
||||
<img src="img/cert_chain.png" height="206" /> </div>
|
||||
<div class="row"></div>
|
||||
<p></p>
|
||||
<p>Note that the "root" certificate is "AddTrust's External
|
||||
CA Root", which issued a certificate to the "COMODO RSA
|
||||
Certification Authority", which in turn issued a certificate
|
||||
to the "COMODO RSA Domain Validation Secure Server CA"
|
||||
which in turn issued our certificate, "*.sslip.io".
|
||||
</p>
|
||||
<p class="lead">How is "sslip.io" pronounced?</p>
|
||||
<p>ESS-ESS-ELL-EYE-PEE-DOT-EYE-OH</p>
|
||||
<p class="lead">Where do I report bugs? I think I found one.</p>
|
||||
<p>Open an issue on <a href="https://github.com/cunnie/sslip.io/issues">GitHub</a>;
|
||||
we're tracking our issues there.</p>
|
||||
<p class="lead">There's a typo/mistake on the sslip.io website. </p>

||||
