(PureBasic) ScMinidriver - Import a Certificate and Private Key to a Smart Card or USB Token

See more ScMinidriver Examples

Demonstrates how to import a certificate and its private key to a key container on a smart card or USB token.

Note: This functionality was introduced in Chilkat v9.5.0.87.

Note: The ScMinidriver functionality is for Windows-only because ScMinidriver DLLs only exist on Windows.
