(C# UWP/WinRT) ScMinidriver - List Certificates on a Smart Card or USB Token

See more ScMinidriver Examples

Gets a list of certificates contained 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. In the next version, Chilkat will be releasing a Pkcs11 class to support Linux, MacOSX, and possibly other operating systems.
