What if we stored the certificate in a filename based on the down
cased SHA256 hash of the cert's name?

This would avoid issues with case insensitive filesystems at the cost
of UX for people who want to directly work with the files on disk
instead of using `puppet cert`

Bug #1168: Master-side client certificates convert hostnames to lowercase
https://projects.puppetlabs.com/issues/1168#change-54792

Author: Mike Brittain

Keywords: certificate, naming
Branch: 


I'm trying to use master-side certificate generation with hosts at Amazon's EC2 
service.  Internal hostnames there use mixed-case names:
<pre>
  domU-12-31-12-34-56-78.compute-1.internal
</pre>
Note the "U" is upper-case.

I build a set of certificates for this client:
<pre>
  puppetca --generate domU-12-31-12-34-56-78.compute-1.internal
</pre>
Resulting files are:
<pre>
  ./private_keys/domu-12-31-12-34-56-78.compute-1.internal.pem
  ./certs/domu-12-31-12-34-56-78.compute-1.internal.pem
  ./ca/signed/domu-12-31-12-34-56-78.compute-1.internal.pem
</pre>
Note all lower-case "u"s in "domu".

When I put these onto the puppet client, they are mis-matched between hostname 
and filenames.  The client (when started) ends up creating new keys with 
mixed-case names next to the versions that were copied from the Puppet master 
server:
<pre>
  -rw------- 1 root root domU-12-31-12-34-56-78.compute-1.internal.pem
  -r-------- 1 root root domu-12-31-12-34-56-78.compute-1.internal.pem
</pre>
It's very possible this is invalid.  I don't know the specs surrounding 
certificate generation.
