Go Corona QR Code Decoder
This repository contains a decoder and verifier for EU Digital COVID Certificate (EUDCC) QR code data, written in Go.
If you got vaccinated and want to know what is stored in the QR code, this package (and example program) can answer that question!
go install github.com/stapelberg/coronaqr/cmd/coronadecode@latest apt install curl zbar-tools curl -sL https://github.com/eu-digital-green-certificates/dgc-testdata/raw/main/CH/png/1.png | \ zbarimg --quiet --raw - | \ coronadecode
(With older Go versions before 1.16, use
go get -u github.com/stapelberg/coronaqr/cmd/coronadecode instead.)
For cryptographic signature
implements loading the trust lists of the German, Austrian or French
governments, which each include all the certificates that are accepted EU-wide.
This is how you would select which trust list to use:
curl -sL https://github.com/eu-digital-green-certificates/dgc-testdata/raw/main/CH/png/1.png | \ zbarimg --quiet --raw - | \ coronadecode -verify -trustlist=trustlistmirror/at
This implementation passes the positive and negative interoperability tests
