Puppet cert inspector

Today while poking around in the puppet source code, I came across a utility in the ext/ directory called cert_inspector. This seems to be a little utility that opens up certificates and interrogates them for useful data. This is better than what I usually do, which is incanting openssl directly. It also is capable of chewing up an entire /var/lib/puppet/ssl directory and dumping information on every cert and key it finds. See the output below:
