Verifiable QR SDK for ICAO Visible Digital Seals

JavaScript Implementation of ICAO Visible Digital Seals, a JSON-based Verifiable QR Credentials.

Install

npm install @pathcheck/vds-sdk --save

Setting up CSCA, DCS and Key IDs

./gen-csca-dsc.sh

It will generate a dsc-worker.p8 file like this:

-----BEGIN PRIVATE KEY-----
MIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0wawIBAQQgZgp3uylFeCIIXozb
ZkCkSNr4DcLDxplZ1ax/u7ndXqahRANCAARkJeqyO85dyR+UrQ5Ey8EdgLyf9Nts
CrwORAj6T68/elL19aoISQDbzaNYJjdD77XdHtd+nFGTQVpB88wPTwgb
-----END PRIVATE KEY-----

and a dsc-worker.pem certificate as:

-----BEGIN CERTIFICATE-----

And a Payload

const TEST_PAYLOAD = {
    "data": {
        "hdr": {
            "t": "icao.vacc",
            "v": 1,
            "is": "UTO"
        },
        "msg": {
            "uvci": "U32870",
            "pid": {
                "n": "Smith Bill",
                "dob": "1990-01-02",
                "sex": "M",
                "i": "A1234567Z",
                "ai": "L4567890Z"
            },
            "ve": [{
                "des": "XM68M6",
                "nam": "Comirnaty",
                "dis": "RA01.0",
                "vd": [{
                    "dvc": "2021-03-03",
                    "seq": 1,
                    "ctr": "UTO",
                    "adm": "RIVM",
                    "lot": "VC35679",
                    "dvn": "2021-03-24"
                }, {
                    "dvc": "2021-03-24",
                    "seq": 2,
                    "ctr": "UTO",
                    "adm": "RIVM",
                    "lot": "VC87540"
                }]
            }]
        }
    }
};

Call the signAndPack to create the JSON String for the QR Code:

const qrValue = await signAndPack(TEST_PAYLOAD, PUBLIC_KEY_PEM, PRIVATE_KEY_P8);

And call the unpack and verify to convert the QR Code information into the payload:

const payload = await unpackAndVerify(qrValue);
