(Excel) ScMinidriver - Import a Certificate to IDPrime MD T=0 Smart Card

See more ScMinidriver Examples

Demonstrates how to import a certificate and its private key to a key container on an ID Prime MD T=0 smartcard.

Note: Requires Chilkat v9.5.0.88 or later. This example only runs on Windows because ScMinidriver is a Windows-only class.
