  • Self verification button used for verification

    Self verification button used for verification

    This is a question that I'm not sure where else to put and didn't find much information about.

    Recently more and more people are not using the scanner app but the self-verification button to control my certificate. This doesn't seem right to me though. I mean someone could use the code here, remove the verification and then has a 'valid' certificate.

    Can you confirm whether this is how this button is intended to be used?

    Maybe this option needs to be rethinked.

    F-Droid inclusion

    Hi, is it OK if we add this app to F-Droid? It seems to be fully FOSS so it would be good to be on there.

    Would you accept a PR to add Fastlane metadata? Cf https://gitlab.com/snippets/1895688

    Thanks for your work and for releasing it as free software :)

  • Cannot find the app

    Cannot find the app

    A lot of comments on the Playstore say that the apps cannot be founded. And it's true. If you search "covid certificate" you can find only "swiss covid" app. Neither the wallet and the checker can be founded.

  • Support certificates from other countries

    Support certificates from other countries

    When importing my German QR code it shows all the data, but also a "Certified with invalid signature" warning.

    From what I understood there is a PKI with a Europe-wide root CA, so I guess it should be easily possible for the app to trust all certificates with signatures that can be tracked to that root CA.

    Name not showing in Singapore-created EUDCC

    Hi!

    I am based in Singapore and recently our government and EU have treated either certificates as equal. I am trying to store the Singapore-produced QR code to the app but got a null null as my name. All the other data seems to be the same compared to this test data. The Covid Check seems to be showing my details just fine but not the Covid Wallet/Cert

    Environment

    App Version 3.1.0 Android 10 EMUI 10.1.0 build 10.1.0.298

    Just want to raise the issue in case it hasn't been noticed before, but realized the implementation is not that long ago.

    Really great work by the way, love that the app is open sourced on Github!

    Building APKs

    Is there any possibility to build the APKs? I do always get strange error messages:

    `Could not determine the dependencies of task ':wallet:compileAbnDebugJavaWithJavac'.

    Could not resolve all task dependencies for configuration ':wallet:abnDebugCompileClasspath'. Could not resolve project :sdk. Required by: project :wallet > project :common > No matching configuration of project :sdk was found. The consumer was configured to find an API of a component, as well as attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug', attribute 'version' with value 'abn', attribute 'org.jetbrains.kotlin.platform.type' with value 'androidJvm' but: - None of the consumable configurations have attributes.`

    Keystore and everything is set up properly!

  • Forged Certificate gets validated

    Forged Certificate gets validated

    Due to a bug in the QR decoder, forged QR Certificates get validated.

    This bug is similar (if not equal) to ministero-salute/it-dgc-verificaC19-android#185 and it can be reproduced as follows.

    Valid Certificate

    QR Valid

    IMG_20211104_201430_883.jpg

    This QR code has the same data as the one below. Sadly it gets validated in the Swiss Covid Checker app.

    Invalid Certificate

    Invalid QR

    Note that, when decoded with zbar, both QR codes have the same data contained.

    Hypothesis

    This feels like a QR Decoding issue. We're discussing it at denysvitali/covid-cert-analysis#9 and at ministero-salute/it-dgc-verificaC19-android#185

  • Doesn't have a valid signature?

    Doesn't have a valid signature?

    Hi,

    At my build, I get "The COVID certificate does not have a valid signature" message on the result screen.

    Same QR Code, but there is no that kind of alert/error message on the official android app.

  • Unable to generate transfer code

    Unable to generate transfer code

    I have a Pixel 4 phone running an up-to-date Android 12 with the latest version of the Covid Cert app installed. When I attempt to generate a transfer code I get an error message: "Unable to generate transfer code. Please contact support." with a phone number. The person at the phone number could not help.

    Other functions of the app seem to work fine.

    Also, the app can generate transfer codes on a Pixel 3a running an up-to-date Android 12.

  • Combination of cert and test cert

    Combination of cert and test cert

    The 2G+ symbole should get also blue colored if a test and another certificate is combined.

    I made the unfortunate experience that some certificate checking personal does not know that 2G+ can be acquiered if a test and a vaccine is combined. They where just looking if the 2G+ symbole was light up blue or not.

  • Make 3G, 2G, 2G+-Status more clearly visible

    Make 3G, 2G, 2G+-Status more clearly visible

    I use my smartphone quite often with a color filter / grayscale mode for not having to much screen time.

    In this situation the vaccination / test status (3G, 2G, 2G+) is due to the choosen colors not clearly visible. I guess this is similar for the iPhone Certificate App.

    Might it be possible to add something not depending on colors, i.e. e striketrough or something similar?

    Here is a sample image of the problem: grafik

  • Add a certificate light for 2G

    Add a certificate light for 2G

    Certificate light is currently not supported for 2G. In a 2G situation the certificate full needs to be shown. This violates the original purpose of having a certificate light.

    The certificate full reveals too much information. The details of the certificate full is not needed to check 2G.

    Implementation hint: It might be necessary to implement a second version of a certificate light to not impair the original certificate light.
