Encrypt MIME using a PEM certificate. C++

#include <CkMime.h>
#include <CkCert.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.

    CkMime mime;

    //  Create a simple MIME message to be encrypted:
    success = mime.AddHeaderField("Content-Type","text/plain");
    success = mime.AddHeaderField("abc","123");
    mime.SetBody("This is a test");

    CkCert cert;
    success = cert.LoadFromFile("qa_data/pem/mf_public_rsa.pem");
    if (success == false) {
        std::cout << cert.lastErrorText() << "\r\n";
        return;
    }

    //  Encrypt the MIME.
    success = mime.Encrypt(cert);
    if (success == false) {
        std::cout << mime.lastErrorText() << "\r\n";
        return;
    }

    //  Display the MIME:
    std::cout << mime.getMime() << "\r\n";

    //  The resulting S/MIME looks like this:

    //  Content-Type: application/x-pkcs7-mime; name="smime.p7m"; smime-type="enveloped-data"
    //  abc: 123
    //  Content-Disposition: attachment; filename="smime.p7m"
