(MFC) Find and Load Certificate by Thumbprint

Demonstrates how to find and load a certificate by SHA1 thumbprint. This is a Microsoft Windows-only example. It assumes the certificate is already installed on the Windows system.

Note: This example requires Chilkat v9.5.0.83 or greater.

#include <CkCert.h>

void ChilkatSample(void)
    {
    CkString strOut;

    // This example requires Chilkat v9.5.0.83 or greater.

    CkCert cert;

    // The thumbprint can be passed in any encoding, such as hex, base64, etc.
    // The 2nd argument indicates the encoding of the 1st argument.
    bool success = cert.LoadByThumbprint("ea5a129c1919a52d238ee28d9f3a8f345b768388","hex");
    if (success == false) {
        strOut.append(cert.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    strOut.append("Found: ");
    strOut.append(cert.subjectDN());
    strOut.append("\r\n");


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
