Send Encrypted Email

Download Chilkat Java Library

Demonstrates how to send encrypted email in Java using the Chilkat email component.

// Chilkat Java Example Program
	
import com.chilkatsoft.CkMailMan;
import com.chilkatsoft.CkEmail;

public class EncryptedEmail {
	
  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  // Sending an encrypted email using the recipient's digital certificate.
  public static void main(String argv[]) 
  {
    CkMailMan mailman = new CkMailMan();
    mailman.UnlockComponent("anything for 30-day trial");
    
    // Set your SMTP server's hostname
    mailman.put_SmtpHost("smtp.comcast.net");
    
    // If your SMTP server requires a login, set username/password
    //mailman.put_SmtpUsername("myUsername");
    //mailman.put_SmtpPassword("myPassword");
    
    // Create a simple email
    CkEmail email = new CkEmail();
    email.put_Subject("Sending mail from Java");
    email.put_Body("This email was sent from a Java program");
    email.put_From("Chilkat Support <support@chilkatsoft.com>");
    // Add a single recipient
    email.AddTo("TagTooga","admin@tagtooga.com");
    
    // There are a number of ways to send digitally encrypted email using Chilkat.
    // This example demonstrates the easiest (other examples will explore
    // some of the other possibilities).
    // To send an encrypted email, you will first need the digital certificate
    // for the recipient. The email address in the certificate should match
    // the recipient's email address.  You do not need the private key to send
    // encrypted email: only the public-key is required.  The recipient however,
    // must have his/her certificate installed with private key in order to decrypt.
    // 
    // If you have the digital certificate in a .cer file, double-click on it from
    // Windows Explorer and install the certificate in the default location.  
    // Chilkat should now be able to locate it.  You only need to set the SendEncrypted
    // property = true to send encrypted email.  
    //
    // That's it.  When SendEmail is called, it will locate the certificate matching
    // the recipient's email address, encrypt the email (including all attachments) and 
    // send it.
    email.put_SendEncrypted(true);
    
    // Note: When sending encrypted mail, only one recipient is allowed.  If you wish
    // to send the same email to multiple recipients, create a program loop to call
    // SendEmail for each recipient.
    boolean success = mailman.SendEmail(email);
    if (!success)
    {
    	mailman.SaveLastError("lastError.txt");	
    }
    
  }
