Valid points. You should ask Github, I’m only reporting. I’m in no way a crypto expert. I can speculate that Heartbleed might reveal enough information to crack the private key, maybe by making available both plain and encrypted versions of the exchange.

I added what I did because if the key is compromised on Github it’s compromised everywhere else you use it.
