Using Client Certificate w/ IMAP SSL

Demonstrates how to use a client-side certificate with an IMAP SSL connection. The SetSslClientCert method is called to specify a certificate to be used for the SSL connection. Java

import com.chilkatsoft.*;

public class ChilkatExample {

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

  public static void main(String argv[])
  {
    boolean success = false;

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

    CkImap imap = new CkImap();

    // To use a secure SSL connection, set SSL and the port:
    imap.put_Ssl(true);
    // The typical port for IMAP SSL is 993
    imap.put_Port(993);

    // Load a certificate from a PFX file and use it.
    // Note: Other methods are available to load pre-installed
    // certificates from registry-based certificate stores.

    // Create an instance of a certificate store object, load a PFX file,
    // locate the certificate we need, and use it for signing.
    // (a PFX file may contain more than one certificate.)
    CkCertStore certStore = new CkCertStore();
    // The 1st argument is the filename, the 2nd arg is the 
    // PFX file's password:
    success = certStore.LoadPfxFile("myCertWithPrivateKey.pfx","secret");
    if (success == false) {
        System.out.println(certStore.lastErrorText());
        return;

    // Find the certificate by the subject common name:
    CkJsonObject jsonCN = new CkJsonObject();
    jsonCN.UpdateString("CN","cert common name");

    CkCert cert = new CkCert();
    success = certStore.FindCert(jsonCN,cert);
    if (success == false) {
        System.out.println(certStore.lastErrorText());
        return;
        }

    // If a PFX file is known to contain a single certificate,
    // you may load it directly into a Chilkat certificate object.
    // This snippet of source code shows how:
    CkCert cert2 = new CkCert();
    // The 1st argument is the filename, the 2nd arg is the 
    // PFX file's password:
    success = cert2.LoadPfxFile("myClientCert.pfx","secret");
