HealthCards Sample Scripts for Python

Please note that these scripts are for demonstrational purposes only. These have not been tested and should not be used directly in production.

Installation

Run the install.sh script in this directory.

./install.sh

The install script takes care of setting up your virtual environment, installing dependencies, etc.

Activating your Virtual Environment

Before you can run scripts, you must first activate your virtual environment. You can do this with the following command:

source myenv/bin/activate

Generate a JWK Set

To generate a random JWK Set, use the following command:

python generate_random_jwks.py jwks.json jwks_private.json

This script will generate the necessary JWK formatted keys, saving the public keyset in jwks.json and the private keyset in jwks_private.json.

Generate a VC

To generate a sample VC, use the following command:

python encode_resource.py jwks_private.json https://commonhealth.org fixtures/vc-c19-pcr-jwt-payload.json sample_vcs/lab_result.smart-health-card

This script uses the private JWK set defined in jwks_private.json, generates a new VC based on ./fixtures/vc-c19-pcr-jwt-payload.json, and saves that in sample_vcs/lab_result.smart-health-card.

Verify a VC

To verifiy a VC, use the following command:

python decode_resource.py sample_vcs/covid19.smart-health-card

This script loads the VC from sample_vcs/covid19.smart-health-card, and verifies it based on the issuer and kid information encoded in the JWS.

Testing locally

You can run a local server to serve .well-known/jwks.json.

Use the following commands:

python generate_random_jwks.py .well-known/jwks.json jwks_private.json
python encode_resource.py jwks_private.json http://localhost:8080 fixtures/vc-c19-pcr-jwt-payload.json sample_vcs/lab_result.smart-health-card

Then, start running a local server:

python -m http.server 8080

Finally, verify the VC using the following command:

python decode_resource.py sample_vcs/lab_result.smart-health-card

Additionally, you can test QR code generation with the sample QR code scanning app and a locally running verifier service using the following command to generate a QR code:

python encode_resource_in_qr_code.py jwks_private.json http://host.docker.internal:8080 fixtures/vc-c19-pcr-jwt-payload.json sample_vcs/lab_result.png

This sets the issuer to http://host.docker.internal:8080, which allows the sample verifier app to resolve port 8080 on the host during verification.
