PKCS11 Login / Logout

See more PKCS11 Examples

Sample code showing how to login and logout of a PKCS11 session. A session becomes authenticated when Login is called, and returns to the unauthenticated state when Logout is called. A smart card's PIN is passed to the Login method.

Note: This example requires Chilkat v9.5.0.88 or later.

C#

bool success = false;

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

//  Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

Chilkat.Pkcs11 pkcs11 = new Chilkat.Pkcs11();

//  Set your shared lib path -- either a full path to the DLL, .so, or .dylib,
//  or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)
pkcs11.SharedLibPath = "aetpkss1.dll";

success = pkcs11.Initialize();
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    return;
}

//  Pass -1 for the slotID to open a session on the first non-empty slot.
int slotID = -1;

//  Open a session.
bool readWrite = true;
success = pkcs11.OpenSession(slotID,readWrite);
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    return;
}

//  Make it an authenticated session by calling Login.
//  The smart card PIN is passed to the Login method.
//  The user type can be one of three choices:
//  0 - Security Officer
//  1 - Normal User
//  2 - Context Specific.
//  You'll likely always login as the Normal User.
int userType = 1;
string pin = "0000";
success = pkcs11.Login(userType,pin);
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    success = pkcs11.CloseSession();
    return;
}

//  Do what is needed with the authenticated session...
//  ...
//  ...

//  Revert to an unauthenticated session by calling Logout.
success = pkcs11.Logout();
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    success = pkcs11.CloseSession();
    return;
}

//  When finished, close the session.
//  It is important to close the session (memory leaks will occur if the session is not properly closed).
success = pkcs11.CloseSession();
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    return;
}

Debug.WriteLine("PKCS11 Login and Logout successfully demonstrated.");
