Probably best not to upload your private key to Github!

If you put production cert & key to config (see README), warning disappear.
Thanks for the report!
P.S. See updated status of issue #2
Last week I wanted to comment about a bug on HN, then I realized it's more constructive to open up an issue on their Github repo.
If nothing else, this might remind those who see it that you can leak private keys / passwords if you put then in source control.
Chris Poole described having this exact problem, in his recent post about 4Chan being hacked - AWS keys in the commit history. (http://chrishateswriting.com/post/84931829578/when-a-bad-day...)
