Covid-QR-Decoder/README.md

Covid Passport Decoder

Extract all payloads included in the Covid QR provided by the Quebec government (Preuve/passeport de vaccination)

Note: The public key does not seem to be provided by the government at this point. Hence, it is not possible to validate QR authenticity at the time being. (Although some of the code is provided in the Python version)

Public keys should be available here later: https://covid19.quebec.ca/PreuveVaccinaleApi/issuer/.well-known/jwks.json
