Load Default Certificate from Smart Card or Token

See more Certificates Examples

Chilkat contains internal logic to examine a connected smart card or USB token, and will make decisions based on make/model to successfully interact with the hardware. When faced with a new smartcard or token, the best starting point is to call LoadFromSmartcard with an empty string argument to see what Chilkat discovers. Unicode C

#include <C_CkCertW.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkCertW cert;

    success = FALSE;

    cert = CkCertW_Create();

    // If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
    CkCertW_putSmartCardPin(cert,L"12345678");

    // To let Chilkat discover what smartcard or token is connected, pass an empty string to LoadFromSmartcard.
    // When testing in this way, it's best to have only a single smartcard or token connected to the system.
    success = CkCertW_LoadFromSmartcard(cert,L"");
    if (success == FALSE) {
        wprintf(L"%s\n",CkCertW_lastErrorText(cert));
        wprintf(L"Certificate not loaded.\n");
        CkCertW_Dispose(cert);
        return;
    }

    // The LastErrorText property on all Chilkat objects will contain 
    // information even when the method call is successful.
    // You can examine the LastErrorText to see what Chilkat found and
    // what decisions were made.
    // 
    // For example, if a certificate was successfully loaded via LoadFromSmartcard,
    // but then signing failed, such as w/ Pdf, XmlDSig, CAdES, etc.,
    // then we would want to examine the LastErrorText from the call to
    // LoadFromSmartcard to get detailed information about the card.
    wprintf(L"%s\n",CkCertW_lastErrorText(cert));

    wprintf(L"Found: %s serial=%s\n",CkCertW_subjectDN(cert),CkCertW_serialNumber(cert));


    CkCertW_Dispose(cert);
