I was working on this coding challenge for a job interview when I ran into a problem: I was getting this error:

ArgumentError: Invalid keyfile or passphrase

But it wasn't coming from the options I was passing, it was happening in a method inside the gem, that I wasn't able to access through the interface. So that meant I had to change the underlying source code.

This SO article which suggested I fork and source the gem, which basically means that you fork the gem, clone it in your local drive, make whatever edits you want to it, and then push the changes to your fork. You then point the gem to the new url, and voila, you are now using the modified gem in your app.

Here's the original piece of code in question:

key = Google::APIClient::PKCS12.load_key(File.open( opts['key'], mode: 'rb'), "notasecret" )

and here are my changes:

key = Google::APIClient::PKCS12.load_key(File.open( opts['key'], mode: 'rb'), "notasecret" )

all i did was add the , mode: 'rb'

I got the idea for this from this article talking about the implementing google api client on Windows, which in turn got its idea from this SO article about PKCS errors. The funny thing is that in the author's case, he felt his issue was that he was working on a windows instead of linux based system. But I had the same problem and I'm working in Mac OS.

So any way, I made the change to the source file.

Then I did the following in my terminal:
