DigiSigner digital signature functionality

DigiSigner creates digital signatures using standard X.509 certificates utilizing public key infrastructure (PKI).
Take a look at the features DigiSigner has to offer:

Feature	Description
Key Store Support	To create digital signatures DigiSigner can use certificates from the following key stores:   •   PKCS#12 (a.k.a PFX) file key stores   •   Smartcards and USB sticks (a.k.a PKCS#11 tokens)   •   MS Windows internal key store
Visible and Invisible Signatures	DigiSigner fully supports both visible and invisible digital signatures. Visible signatures can be easily positioned anywhere in the document using the mouse pointer.
Signature Appearances	For the visible signatures DigiSigner lets you design your own signature appearances. Signature appearances can be easily managed, edited or removed.
Certification Levels	By signing the document you can specify the certification level of the signature to control allowed and disallowed changes in the signed document.
Timestamp Server Support	DigiSigner fully supports time stamped signatures. You just need to specify the timestamp server address.
Signature Verification	DigiSigner shows and verifies existing digital signature in the document. To verify the signature you just have to click on it.
Hash Algorithms	To create digital signatures DigiSigner supports SHA1 and SHA2 (SHA256, SHA384, SHA512) hash algorithms.
Adobe Reader Compatibility	DigiSigner produces fully Adobe Reader compliant digital signatures, which can be verified in Adobe Reader and vice versa.

What is DigiSigner Kit?

DigiSigner Kit is a software development kit, which includes DigiSigner library, documentation and examples. With DigiSigner Kit you can start using DigiSigner functionality in your applications immediately. Demo version of DigiSigner Kit can be downloaded from our download page.

Differences between DigiSigner Kit Demo and Prod versions

The Demo Version of DigiSigner Kit contains the full functionality DigiSigner has to offer, but with two restrictions: on every page in the document a demo mode message is displayed and every signature you create will add a watermark to your document. The Prod version doesn't have these restrictions and is intended to be used in production.
You can use the Demo Version to evaluate DigiSigner. When you are ready you can seamlessly migrate to the Prod Version. All you will have to do is replace demo digisigner.jar library file with the prod one. No code changes are required.

How easy is it to embed DigiSigner in my application?

It is very easy. Here is the complete code of the application to display the PDF document specified as command line parameter. The PDF signing functionality is of course also included in the application.

						import javax.swing.*;
						import com.digisigner.api.DigiController;
                        import com.digisigner.api.DigiSigner;
                        import com.digisigner.api.DigiViewBuilder;

						
						/**
						 * How to use DigiSigner to build a PDF viewer component. 
						 */
						public class ViewerComponent {						
						  public static void main(String[] args) {							
							DigiController controller = DigiSigner.createController();
		                    DigiViewBuilder builder = DigiSigner.createViewBuilder(controller);
							
							// create pdf viewer panel 
					        JPanel viewerPanel = builder.buildViewerPanel();
					
					        // create your own application frame and add the panel to this frame
					        JFrame applicationFrame = new JFrame();
					        applicationFrame.getContentPane().add(viewerPanel);				
					        applicationFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
					        controller.openDocument(args[0]); // open document
					        applicationFrame.pack();
					        applicationFrame.setVisible(true); // show frame
	  					  }
						}
