ScMinidriver - Import Private Key to Smart Card

See more ScMinidriver Examples

Demonstrates how to import a private key to the "signature" or "key exchange" location in the Nth key container on a smart card. Tcl

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Chilkat recommends the following free tool for interactively examining the contents of your smart card
# through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

# Let's first look at our smart card before importing a private key.
# Here's the view of our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:

# First let's load a private key into the Chilkat private key object.
# (Chilkat provides the ability to load private keys from many different sources and formats.
# this example loads from a PEM file.)
