PKCS11 Find Private Key by Label

See more PKCS11 Examples

Demonstrates how to find a private key based on a user-specified label.

Note: This example requires Chilkat v9.5.0.96 or later.

C++

#include <CkPkcs11.h>
#include <CkJsonObject.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;

    //  Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
    //  For example:
    pkcs11.put_SharedLibPath("C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS11.dll");

    //  Use your HSM's PIN.
    const char *pin = "0000";

    //  Normal user = 1
    int userType = 1;

    //  Establish a logged-on user session with the HSM.
    success = pkcs11.QuickSession(userType,pin);
    if (success == false) {
        std::cout << pkcs11.lastErrorText() << "\r\n";
        return;
    }

    //  Provide a template to find a PKCS11 object.
    CkJsonObject jsonTemplate;

    //  Find an RSA private key with the label "MySshKey".
    //  Here's an example of how the key was originally imported: 
    //  PKCS11 Import SSH Key
    jsonTemplate.UpdateString("class","private_key");
    jsonTemplate.UpdateString("key_type","rsa");
    jsonTemplate.UpdateString("label","MySshKey");

    unsigned long privKeyHandle = pkcs11.FindObject(jsonTemplate);
    if (privKeyHandle == 0) {
        std::cout << pkcs11.lastErrorText() << "\r\n";
        return;
    }

    //  The private key handle is only valid during the PKCS11 session.
    //  If you wish to use the private key in another PKCS11 session,
    //  you'll first need to find it.  See:  
    std::cout << "private key handle: " << privKeyHandle << "\r\n";

    //  Do whatever you wish with the private key handle...
    //  ...
    //  ...

    pkcs11.CloseSession();
