    // Note: Requires Chilkat v9.5.0.65 or greater.

    // This requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // First generate an RSA private key.
    CkRsaW rsa;

    // Generate a random 2048-bit RSA key.
    bool success = rsa.GenerateKey(2048);
    if (success != true) {

        return;
    }

    // Get the private key
    CkPrivateKeyW *privKey = rsa.ExportPrivateKeyObj();

    // Create the CSR object and set properties.
    CkCsrW csr;

    // Specify the Common Name.  This is the only required property.
    // For SSL/TLS certificates, this would be the domain name. 
    // For email certificates this would be the email address. 
    csr.put_CommonName(L"mysubdomain.mydomain.com");

    // Country Name (2 letter code)
    csr.put_Country(L"GB");

    // State or Province Name (full name)
    csr.put_State(L"Yorks");

    // Locality Name (eg, city)
    csr.put_Locality(L"York");

    // Organization Name (eg, company)
    csr.put_Company(L"Internet Widgits Pty Ltd");

    // Organizational Unit Name (eg, secion/division)
    csr.put_CompanyDivision(L"IT");

    // Email address
    csr.put_EmailAddress(L"support@mydomain.com");

    // Create the CSR using the private key.
    const wchar_t *pemStr = csr.genCsrPem(*privKey);
    if (csr.get_LastMethodSuccess() != true) {
        wprintf(L"%s\n",csr.lastErrorText());
        delete privKey;
        return;
    }

    // Save the private key and CSR to a files.
    privKey->SavePkcs8EncryptedPemFile(L"password",L"qa_output/privKey1.pem");
    delete privKey;

    CkFileAccessW fac;
    fac.WriteEntireTextFile(L"qa_output/csr1.pem",pemStr,L"utf-8",false);

    // Show the CSR.
    wprintf(L"%s\n",pemStr);

    // Sample output:
    // The CSR PEM can be checked here:
    // https://www.networking4all.com/en/support/tools/csr+check/
    // Copy-and-paste the PEM into the online CSR Decoding / CSR Verification form
