Find Certificate for Email Encryption

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

    success := false

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

    mailman := chilkat.NewMailMan()

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

    // Create a new email object
    email := chilkat.NewEmail()

    email.SetSubject("This email is encrypted")
    email.SetBody("This is a digitally encrypted mail")
    email.SetFrom("Joe <joe@example.com>")
    // Emails are encrypted using the recipient's certificate.
    recipientEmailAddr := "jane@example2.com"
    email.AddTo("Jane",recipientEmailAddr)

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

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

    cert := chilkat.NewCert()
    // 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 {
        fmt.Println(cert.LastErrorText())
        mailman.DisposeMailMan()
        email.DisposeEmail()
        cert.DisposeCert()
        return
    }

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

    success = mailman.SendEmail(email)
    if success != true {
        fmt.Println(mailman.LastErrorText())
    } else {
        fmt.Println("Encrypted Mail Sent!")
    }


    mailman.DisposeMailMan()
    email.DisposeEmail()
    cert.DisposeCert()
