Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

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

// The mailman object is used for sending and receiving email.
Chilkat.MailMan mailman = new Chilkat.MailMan();

// Set the SMTP server.
mailman.SmtpHost = "smtp.comcast.net";

// Load the .cer file into a certificate object.
// When sending S/MIME encrypted email, it is the recipient's
// certificate that is used for encryption.  Only the public key
// is needed to encrypt.  The recipient is the only
// one possessing the private key, and therefore is the only
// one able to decrypt.
Chilkat.Cert cert = new Chilkat.Cert();
bool success = cert.LoadFromFile("cknotes.cer");
if (success != true) {
    Debug.WriteLine(cert.LastErrorText);
    return;
}

// Create a new email object
Chilkat.Email email = new Chilkat.Email();

email.Subject = "This email is encrypted";
email.Body = "This is a digitally encrypted mail";
email.From = "Chilkat Support <support@chilkatsoft.com>";
success = email.AddTo("Chilkat Blog","admin@cknotes.com");

// Indicate that the email is to be sent encrypted.
email.SendEncrypted = true;

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

success = await mailman.SendEmailAsync(email);
if (success != true) {
    Debug.WriteLine(mailman.LastErrorText);
}
else {
    Debug.WriteLine("Mail Sent!");
}
