Export Google Authenticator secret OTP-keys

I recently got myself a Yubikey and wanted to set up the Yubico Authenticator with all the OTPs I had in Google Authenticator. Unfortunately Yubico Authenticator doesn't support scanning the QR-code that the Google Authenticator generates when you export the OTP-keys, and it seemed like quite the daunting task to log in to every service to generate new OTP-keys. So I decided to have a look at the contents of the QR code, to see if I could import the keys into Yubico Authenticator in one go. Luckily I found a blog post by Alex Bakker that describes the data format.

Unfortunately, but likely for the best, the security policy of Google Authenticator won't allow you to take a screenshot of
