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

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

local scmd = chilkat.ScMinidriver.new()

-- Reader names (smart card readers or USB tokens) can be discovered
-- via List Readers or Find Smart Cards

-- If successful, the name of the currently inserted smart card is available:

-- To import a cert + private key, we'll need to be PIN authenticated.
-- For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
