pub fn sign_credential_jwt(
vc: &VerifiableCredential,
signer: &dyn Signer,
kid: &str,
) -> Result<String>Expand description
Sign a VerifiableCredential as a JWT.
Returns the compact JWT serialization. The kid should be a DID URL
identifying the verification method (e.g., did:key:z6Mk...#z6Mk...).
Per the VC-JWT spec, valid_from maps to nbf and valid_until maps
to exp. An iat (issued-at) claim is always included.
