Code Skeleton to Establish Connection Between a .NET Application and the HSM

After all previous configuration steps have been done, it should be now possible to use Pkcs11Interop interface API to provide the .NET application with an end-to-end connection to Utimaco HSM device. The following shortest code skeleton can be used to establish this bridge:

›_ Console
using Net.Pkcs11Interop. ighLevelAPI; static void Main(string[] args) { // Path to unmanaged library provided by the device vendor String path = "cs_pkcs11_R2.dll"; // Unmanaged PKCS#11 library is loaded by the constructor of Pkcs11 class. // Every PKCS#11 library needs to be initialized with C\_Initialize method // which is also called automatically by the constructor of Pkcs11 class. Pkcs11 pkcs11 = new Pkcs11(path, false); // find accessible slot of the token List<Slot> slots = pkcs11.GetSlotList(true); Slot slot = slots[0]; Session session = slot.OpenSession(false); String pin = "1234"; session.Login(CKU.CKU_USER, pin); session.Logout(); session.CloseSession(); // Unmanaged PKCS#11 library is unloaded by Dispose() method. // C_Finalize should be the last call made by an application and it // is also called automatically by Dispose() method. pkcs11.Dispose(); }

›_ Console

using Net.Pkcs11Interop. ighLevelAPI;

static void Main(string[] args)

{

// Path to unmanaged library provided by the device vendor

String path = "cs_pkcs11_R2.dll";

// Unmanaged PKCS#11 library is loaded by the constructor of Pkcs11 class.

// Every PKCS#11 library needs to be initialized with C\_Initialize method

// which is also called automatically by the constructor of Pkcs11 class.

Pkcs11 pkcs11 = new Pkcs11(path, false);

// find accessible slot of the token

List<Slot> slots = pkcs11.GetSlotList(true);

Slot slot = slots[0];

Session session = slot.OpenSession(false); String pin = "1234"; session.Login(CKU.CKU_USER, pin); session.Logout(); session.CloseSession();

// Unmanaged PKCS#11 library is unloaded by Dispose() method. // C_Finalize should be the last call made by an application and it

// is also called automatically by Dispose() method.

pkcs11.Dispose();

}
