Hannob inspired me with his vacdec
[https://github.com/hannob/vacdec]https://github.com/hannob/vacdec
Python script to encode something like EU Covid-19 vaccine certificate.
This script takes a string with python dictionary string as parameter and create output.png It is reversed version of Hannobs's vacdec. You need to get own sample data.
You will need the python cbor2 and base45 packages. You can install them via your distribution or via pip:
pip install base45 cbor2
In your system you need qrencode. Exapmle for Fedora34.
dnf install qrencode
Run:
./vacenc sample_data.txt
