Find Certificate for Email Encryption

Demonstrates finding the recipient's certificate in the Windows certificate store and using it to send encrypted email. C++

#include <CkMailMan.h>
#include <CkEmail.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.

    CkMailMan mailman;

    //  Set the SMTP server.
    mailman.put_SmtpHost("smtp.example.com");

    //  Create a new email object
    CkEmail email;

    email.put_Subject("This email is encrypted");
    email.put_Body("This is a digitally encrypted mail");
    email.put_From("Joe <joe@example.com>");
    //  Emails are encrypted using the recipient's certificate.
    const char *recipientEmailAddr = "jane@example2.com";
    email.AddTo("Jane",recipientEmailAddr);

    //  Indicate that the email is to be sent encrypted.
    email.put_SendEncrypted(true);

    //  This example demonstrates finding the email encryption certificate
    //  on a Windows system where the certificate is stored in the Windows 
    //  certificate store.

    CkCert cert;
    //  The recipient's certificate is used to encrypt.
    //  (Because the recipient is the only one in possession of the private key to decrypt.)
    success = cert.LoadByEmailAddress(recipientEmailAddr);
    if (success != true) {
        std::cout << cert.lastErrorText() << "\r\n";
        return;
    }

    //  Specify the certificate to be used for encryption.
    success = email.SetEncryptCert(cert);

    success = mailman.SendEmail(email);
    if (success != true) {
        std::cout << mailman.lastErrorText() << "\r\n";
