Examples of iaik.x509.X509Certificate.sign()

iaik.x509.X509Certificate.sign()

This methods implements an easy way to sign your certificate. Note that TBSCertificate must be set before calling this method. @param sig a Signature engine that is initialized for signing with the appropriate private key @param signerPub the signer's public key @throws SignatureException if the signature could not be done @throws CertificateEncodingException if an error occured during tbsCertificate encoding @throws NoSuchAlgorithmException if the Public key or is not available signature algorithm @throws InvalidAlgorithmParameterException if signature algorithm parameters could not be encoded correctly

      if (!comment.equals("")) {
    cert.addExtension(new NetscapeComment(comment));
      }
      cert.sign(AlgorithmID.md5WithRSAEncryption,kp.getPrivate());


      X509Certificate[] chain = new X509Certificate[1];
      chain[0] = cert;


      /* encrypt the key and save the cert */

   * This is the private key out of the server's certificate, 
   */

      cert.sign(AlgorithmID.md5WithRSAEncryption, serverKey);
  } catch (InvalidKeyException e) {
      System.out.println("OOPS " + e);
      e.printStackTrace();
