Send Signed EmailDemonstrates how to send digitally signed email in Java using the Chilkat email component. // Chilkat Java Example Program import com.chilkatsoft.CkMailMan; import com.chilkatsoft.CkEmail; public class SignedEmail { static { try { System.loadLibrary("chilkat"); } catch (UnsatisfiedLinkError e) { System.err.println("Native code library failed to load.\n" + e); System.exit(1); } } // Send a signed email using the sender'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 signed mail from Java"); email.put_Body("This email was sent from a Java program"); email.put_From("TagTooga <admin@tagtooga.com>"); // Add a few recipients email.AddTo("Matt","matt@chilkatsoft.com"); email.AddTo("Support","support@chilkatsoft.com"); // There are a number of ways to send digitally signed email using Chilkat. // This example demonstrates the easiest (other examples will explore // some of the other possibilities). // To send a signed email, the digital certificate matching the sender's email // address (in the FROM header field) should have been previously be installed on your computer // with the private key. // If not, you may install from a .pfx (or .p12) file. // Double-click on the .pfx to install. Do not check the "Enable strong private key // protection" checkbox because if you do, programs that access the private key // will cause the operating system to display a pop-up warning dialog to // notify the logged-in user of the private key access. Otherwise, select all the // defaults and import the certificate. // // IMPORTANT: The .pfx should be imported from the same logged-in account // under which the program will be running. This is because private keys // are stored by Windows within the logged-on user's "protected store". // // Once the PFX is installed, the Chilkat component should be able to locate // the certificate for signing. You only need to set the SendSigned property = true: email.put_SendSigned(true); boolean success = mailman.SendEmail(email); if (!success) { mailman.SaveLastError("lastError.txt"); } } } |
