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.

C++

#include <CkPkcs11.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.

    CkPkcs11 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("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) {
        std::cout << pkcs11.lastErrorText() << "\r\n";
        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) {
        std::cout << pkcs11.lastErrorText() << "\r\n";
        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) {
        std::cout << pkcs11.lastErrorText() << "\r\n";
        return;
    }

    std::cout << "PKCS11 session successfully opened and closed." << "\r\n";
    }
