I recently started working at Verily, a sister company to Google, which focuses on healthcare and life sciences. I've been learning about the tech used to generate the COVID QR codes including the FHIR data format, and the SMART app framework. When I received my vaccination QR code it seemed like a perfect opportunity to dive in deeper.
At first I found a few Python decoding examples ( , ). but I didn't want to go through the hassle of setting up a Python workspace. Then I found shc-covid19-decoder but it didn't work for me. I couldn't stop thinking about it so I decided to make my own. In the end, I found it a consuming learning experience as I dove into the quirks of JWTs, base64 encoding, and zlib compression used by SMART Health Cards.
