Hi, I am trying to implement an app which performs cert based authentication through smart card. I have few queries related to the same I have included com.apple.token in the key chain accessory group. I am able to fetch the certificates from the keychain using Yubi key Type c. But this is not working for Yubi key lighting port. Does Apple support lighting port readers? What is the need of crypto token kit extension if we are able to list the certificates from key chain just by adding com.apple.token in the entitlements file.
