Add credential vct schema validation at retrieval #700
Description
Problem Statement
Checking the integrity of the issued verifiable credentials according to their vct help to ensure emitted credentials are valid. That verification can be made using the schema associated to the vct, validating the credential response at retrieval. That schema is available in the credential vct metadata described by SD-JWT-based Verifiable Credentials (SD-JWT VC)
Proposed Solution
@sd-jwt/sd-jwt-vc library offer to validate the schema, the integration in wallet-common is on the way wwWallet/wallet-common#13. Wait for it to be merged before starting the issue.
