PKCS11 Find Driver Files

See more PKCS11 Examples

Uses Chilkat's SCard class to find smartcards/tokens present on the system (Windows/Linux/Mac/etc.) to return information about the expected PKCS11 drivers (DLL, shared lib, dylib) and the confirmed existing PKCS11 drivers present on the system.

Once the PKCS11 driver file is discovered, it can be used as a starting point with the PKCS11 class, which is shown in this example.
