(PowerBuilder) ScMinidriver - Get Public Keys from Smart Card Key ContainerSee more ScMinidriver ExamplesDemonstrates how to query a key container on a smart card (or USB token) to get the public part of the private keys that are present. A key container can hold two separate private keys -- one in the "signature" position, and the other in the "key exchange" position.
