PKCS11 Sessions

See more PKCS11 Examples

Sample code showing how to open a PKCS11 session and then later close it.

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

Unicode C++

#include <CkPkcs11W.h>

void ChilkatSample(void)
    {
    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.

    CkPkcs11W 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.put_SharedLibPath(L"ShuttleCsp11_3003.dll");

    // Starting in Chilkat v9.5.0.96, there is a shorter way to establish
    // a PKCS11 session with login.
    // The QuickSession method was added in v9.5.0.96 and is the equivalent of 
    // calling Initialize, OpenSession, and Login.  

    success = pkcs11.Initialize();
    if (success == false) {
        wprintf(L"%s\n",pkcs11.lastErrorText());
        return;
    }

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

    // Open a read/write session.
    bool readWrite = true;
    success = pkcs11.OpenSession(slotID,readWrite);
    if (success == false) {
        wprintf(L"%s\n",pkcs11.lastErrorText());
        return;
    }

    // Do whatever is needed...
    // ...
    // ...

    // 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) {
        wprintf(L"%s\n",pkcs11.lastErrorText());
        return;
    }

    wprintf(L"PKCS11 session successfully opened and closed.\n");
    }
