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.

Swift

func chilkatTest() {
    var success: Bool = 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.

    let pkcs11 = CkoPkcs11()!

    // 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 {
        print("\(pkcs11.lastErrorText!)")
        return
    }

    // Pass -1 for the slotID to open a session on the first non-empty slot.
    var slotID: Int = -1

    // Open a session.
    var readWrite: Bool = true
    success = pkcs11.openSession(slotId: slotID, readWrite: readWrite)
    if success == false {
        print("\(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.
    var userType: Int = 1
    var pin: String? = "0000"
    success = pkcs11.login(userType: userType, pin: pin)
    if success == false {
        print("\(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 {
        print("\(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 {
        print("\(pkcs11.lastErrorText!)")
        return
    }

    print("PKCS11 Login and Logout successfully demonstrated.")
