Scriptable green pass verifier. With this application you can automatize accesses based on green pass validity.
You need to have pip and libzbar to install the application.
You can install it using your favorite package manager, for instance in Ubuntu:
$ sudo apt install python3-pip libzbar0
You can just install the application using pip:
$ pip install greenpass
If you want to install it from sources, install the python3 requirements using the following command:
$ pip3 install -r requirements.txt
You can feed the application with different file formats, for instance:
Green pass official PDFs
$ greenpass --pdf greenpass.pdf
QRCode images in PNG
$ greenpass --qr greenpass.png
Txt files with the content of the qrcode
$ greenpass --txt greenpass.txt
Standard input and pipes
$ zbarimg --raw greenpass.png | greenpass --txt -
On a side note, you can verify camera-acquired images if your scanner prints the raw content of the QRcode on stdout
$ zbarcam --raw -q1 | greenpass --txt -
The application returns an UNIX compatible code, therefore you can concatenate commands that will be executed only if the green pass is verified.
$ greenpass --qr greenpass.png && echo "green pass ok"
You can also get the expiration configuration using --settings
without
other inputs.
$ greenpass --settings
