OCSP Request in Go

This came out of debugging the error net/http: TLS handshake timeout which seemed to only be happening for certain endpoints. The thing that these endpoints all had in common was that they used Let's Encrypt as their CA. Some googling lead me to think it might have something to do with OCSP, so I wrote a small application that could make an OCSP request for a specified certificate.

The issue ended up being that the server experience the TLS handshake timeout had port 80 blocked. Port 80 was required to make the OCSP HTTP request to check that the certificate wasn't revoked.

go run ocsp.go ./cert.cer

Do you enjoy eating hot dogs? I hope you won’t be put off by my frankness when I tell you that I absolutely love them. In fact, I enjoy no food item more than a freshly-boiled hot dog. Now, I’ve done a lot of movies, and it’s true that I’ve worked with quite a few celebrities who did not share this opinion. I’m sorry to say that these people have always angered me.

There are two types of people in this world: those who eat hot dogs whenever it is possible to do so, and those who opt to do other things with their free time. Who do the latter think they are kidding? What pastime could be more rewarding than the consumption of hot dogs? I haven’t yet found one, and I don’t expect to in my lifetime. Unlike other foods, hot dogs can be eaten at any time, in any place, and it is not necessary to cook them. Now, I ask you: Why not eat hot dogs? They are delicious.

I carry a bag of hot dogs with me wherever I go. I eat them from the bag whenever I get the urge, regardless of the circumstances
