Cryptographic operations with the Card Manager

Post by poinonche » Sun Oct 01, 2017 8:00 am

I would like to put a cryptographic key on the card and read it back afterwards by using the functionality of the Issuer Security Domain only. Is it feasible? Also, can I do cryptographic operations only by using the ISD?

You cannot do cryptographic operations with ISD. You must write an applet and use KeyPair and Signature class.

But is it possible to store a key to the smart card using the ISD only? What about reading the key back?

Due to security reasons reading the key back is prohibited. You can only get information what type of key is stored.
