This Python code decodes the content of QR codes that represent Covid Passports
Since people are very wary of sharing their own QR codes, this has received limited testing with NHS Digital-generated codes. Please test it with your own QR codes and report any issues.
This code was written in Python 3. You will need Python 3 installed to use it.
pip3 install -r requirements.txtto install dependencies
python cli.py 'HC1:long string'to decode the string
Note that you must use single quotes in step two because the string will probably have dollar symbols in it
To use the web version you'll need to be able to serve the page over https. We use caddy for this, and specify our own IP address when testing it locally.
