(JavaScript) Find Certificate for Email Encryption

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

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var mailman = new CkMailMan();

// Set the SMTP server.
mailman.SmtpHost = "smtp.example.com";

// Create a new email object
var email = new CkEmail();

email.Subject = "This email is encrypted";
email.Body = "This is a digitally encrypted mail";
email.From = "Joe <joe@example.com>";
// Emails are encrypted using the recipient's certificate.
var recipientEmailAddr = "jane@example2.com";
email.AddTo("Jane",recipientEmailAddr);

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

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

var cert = new CkCert();
// 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) {
    console.log(cert.LastErrorText);
    return;
}

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

success = mailman.SendEmail(email);
if (success !== true) {
    console.log(mailman.LastErrorText);
}
else {
    console.log("Encrypted Mail Sent!");
