    ; ---------------------------------------------------------------------------------------------------------
    ; The following is true only for Chilkat v10.1.1 and earlier:
    ; Also, the Chilkat CertStore class can only use MS CNG or CryptoAPI.
    ; Some smartcard/USB token drivers only support PKCS11 or ScMinidriver.
    ; You may get better results using Chilkat.Cert.LoadFromSmartcard because
    ; Cert.LoadFromSmartcard can automatically detect and utilize PKCS11, ScMinidriver, CNG, and CryptoAPI.
    ; ---------------------------------------------------------------------------------------------------------
    ; Starting in Chilkat versions after v10.1.1, OpenSmartcard also works with
    ; Apple Keychain and PKCS11 drivers on Windows, Linux, and MacOS.
