Use a Smart Card Certificate + Private Key for SSL/TLS Authentication
See more ScMinidriver Examples
Demonstrates how to use a certificate + private key located on a smart card for the TLS client certificate in an HTTPS request.Note: This example only works on Windows. ScMinidriver is a Windows-specific smart card and USB token minidriver that enables smart card authentication and cryptographic operations within Windows operating systems.
