Retrieving Trust Marks

1. Inputs to Trust Mark Issuer:

   • id: The identifier for the Trust Mark (e.g., http://dc4eu.example.com/EHICCredential/se).
   • sub: The entity's entity_id.

2. Steps:

   • Supply the id and sub to the Trust Mark Issuer.

   • Retrieve the issued Trust Mark as a signed JWT.

3. Validation:

   • Use a JWT library to verify the Trust Mark's signature using the Trust Mark Issuer's public key:
     • Retrieve public keys from the Trust Mark Issuer's /.well-known/jwks.json endpoint.
     • Validate claims such as iss, sub, id, and iat for compliance.

4. Include in Metadata: Add issued Trust Marks to your issuer’s metadata:

   Code Block
   language yml
   trust_marks: - "eyJhbGciOiJIUzI1NiIsInR..." - "eyJhbGciOiJIUzI1NiIsInR..."

   
   

How to Add Trust Marks to the vc_up_and_running Issuer

To update the Trust Marks, you need to modify the trust_marks section of the satosa/plugins/oidc_frontend.yaml file. Follow the steps below to replace the existing Trust Marks with the ones received from the federation operator.

1. Locate the Trust Marks Section

   In the current configuration, the trust_marks are defined under: 

   Code Block
   language yml
   trust_marks: - <existing-trust-mark-1> - <existing-trust-mark-2>

   You need to replace these values with the new Trust Marks provided by the federation operator.

2. Example Update 

   If the federation operator provided the following new Trust Marks:

   Code Block
   language yml
   eyJhbGciOiJSUzI1NiIsImtpZCI6IjM2NWQ2MjY3LTI5MzQtNGJhNy05YjEyLWU4ZmFkNTYwYjZjMyJ9... eyJhbGciOiJSUzI1NiIsImtpZCI6IjkwNTFjZTgzLTY1NzEtNDliYi04ODdjLTc3OWQzMDNmOTRmYyJ9...

   Modify the trust_marks section as follows: 

   Code Block
   language yml
   trust_marks: - eyJhbGciOiJSUzI1NiIsImtpZCI6IjM2NWQ2MjY3LTI5MzQtNGJhNy05YjEyLWU4ZmFkNTYwYjZjMyJ9... - eyJhbGciOiJSUzI1NiIsImtpZCI6IjkwNTFjZTgzLTY1NzEtNDliYi04ODdjLTc3OWQzMDNmOTRmYyJ9..

   
   

3. Restart the Issuer to Apply Changes

   Once you've updated the configuration file, restart the Issuer container to apply the changes: 

   Code Block
   language bash
   ./stop.sh && \ ./start.sh

   
   

4. Verify the Changes
   After restarting the Issuer, verify that the new Trust Marks are correctly applied:
   

   Code Block
   language bash
   curl -k -s https://<issuer-host>:8000/.well-known/openid-federation | cut -d '.' -f2 | tr '_-' '/+' | base64 -d 2>/dev/null | jq .

   Look for the updated trust_marks in the JSON response.

Testing Trust Marks

1. Decode JWT: Use tools like jwt.io to inspect the Trust Mark's claims and ensure all required fields are present.

2. Verify Signature: Validate the JWT signature against the Trust Mark Issuer's public key.

3. Check Expiration: Ensure the exp claim (if present) has not expired.

4. Validate References: Follow the ref URL (if provided) to confirm compliance with human-readable policy documents.
