this would be useful...

[marvinsxtr]

We would need example QR codes to debug this. Otherwise this should be easy to implement.

I don't have one right now, but I can try and get one...

maybe there are useful specs here? -> https://ec.europa.eu/health/sites/default/files/ehealth/docs/digital-green-certificates_v5_en.pdf

Just found a test certificate and a pixelated recovery certificate which we could try.

@marvinsxtr Does it matter that both examples don't have a valid signature?

[marvinsxtr]

Not really, what's most important is that they are recognized by Corona-Warn-App or CovPass. Have you tried the recovery cert? @Ein-Tim

[Ein-Tim]

They are recognized but CovPass shows "COVID-Zertifikat enthält keine gültige Signatur" and CWA is not able to scan recovery or test certificates in version 2.4, this feature will be added in version 2.5...

[marvinsxtr]

That should suffice for our testing purposes.

[marvinsxtr]

We can use the official dgc testdata repository for testing purposes from now on as described in #33. The repository includes test data for countries like UK where this web app does not work with vaccination certificates either.

Closing this with reference to #34.
