Shows how to get the SHA256 hash of a certificate. Unicode C++

#include <CkCertW.h>
#include <CkBinDataW.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkCertW cert;

    // Load a certificate object with a certificate.
    // The certificate object could have come from any source,
    // or perhaps was obtained from another Chilkat function.
    // The source does not matter.  What matters is that we have
    // a cert object loaded with the certificate..
    success = cert.LoadFromFile(L"qa_data/certs/cert_test123.cer");
    if (success != true) {
        wprintf(L"%s\n",cert.lastErrorText());
        return;
    }

    // Get the binary DER of the certificae, and compute the SHA256 hash:
    CkBinDataW bdDer;
    cert.ExportCertDerBd(bdDer);

    // Get the base64 representation of the SHA256 hash.
    const wchar_t *certHash = bdDer.getHash(L"sha256",L"base64");

    wprintf(L"Certificate hash in base64 = %s\n",certHash);
