  • Verifying valid EU-DCC fails with general ecdsa.Verify error.

    Verifying valid EU-DCC fails with general ecdsa.Verify error.

    Describe the bug

    Signature validation fails for valid EU-DCC Vaccine passport.

    The bug might be a marshaling issue in the order of the Protected Headers map contents (KID and ALGO). COSE Libraries in NodeJS and Python seem to validate the Pass just fine. Go-COSE seems to fail.

    Passes generated with this package validate the signature fine (when using the custom public key and not the certificates from EU-DGC gateway)

    To Reproduce

    Call the Verify Function on a valid EU-DCC Vaccine Passport that was NOT generated by this package (A valid one from the Ministry of Health).

    Expected behavior

    Signature should be validated and return no error

  • Fetching KIDs and Signer Certificates is very slow

    Fetching KIDs and Signer Certificates is very slow

    Describe the bug

    Fetching KIDs and Signer Certificates is very slow since the requests are sequential (1-by-1) for around 252 different Signer Certificates.

    Expected behavior

    Some kind of caching or multi-threaded approach might improve performance. Currently verifying a pass can take up to 1 min.
