DigiSigner Applet Features
DigiSigner Applet is a Java PDF viewer with an advanced digital signing functionality. Please take a look at the list of features DigiSigner can offer you.
Support for Smartcards and USB sticks
To create digital signatures DigiSigner Applet can access your smartcards or USB sticks through the MS Windows key store (on Windows) or PKCS#11 interface (on all platforms). This is the list of key stores that we support:
- MS Windows internal key store
- Smartcards and USB sticks (a.k.a PKCS#11 tokens)
- Apple Keychain key store
- PKCS#12 (a.k.a PFX) file key stores
Time Stamp Server Support
DigiSigner fully integrates with the standard Time Stamp Servers according to the RFC 3161 Time Stamp Protocol. You can specify the server settings through the configuration options and your users don't need to enter them explicitly.
Signature Appearances
Digital signatures must not always look the same. DigiSigner Applet lets you design your own signature appearances. It is very easy to use different images or fonts. Signature appearances can be managed, edited or removed.
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.
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.
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.
How to Install DigiSigner Applet
DigiSigner Applet can be delivered in two distributions:
- Binary distribution
- Source distribution
Binary distribution
Binary distribution is the easiest one to install. Use it if all your requirements are covered by our configuration options.
How to install:
- Download the binary distribution from our Download section.
- Copy the distribution archive to your web server and unpack it there.
- Point the browser to the file DigiApplet.html to start the applet.
- Do you want to include DigiSigner Applet in your own web page?
Then open the source of DigiApplet.html and copy the content between the lines
<!-- DIGISIGNER APPLET START --> and <!-- DIGISIGNER APPLET END -->
in your own web page. - If you want, that the signed documents are automatically saved on your server,
start the server script in the server directory (startServer.bat or startServer.sh).
You will find the saved document in server/signed_pdfs directory.
Source distribution
Source distribution includes the source code of the DigiSigner Applet class and the build script to build the applet. The source distribution lets you implement your custom integration with your web application, add additional validation or create reaction on certain events like document signing or saving.
How to install, customize and build DigiSigner Applet:
- If you are going to make changes to the applet's source code you have to install JDK and ANT build tool first.
- Download the source distribution from our Download section and unpack it.
- You will find the applet's source code under src/DigiApplet.java. You can change the code in this class according to your needs.
- After you are finished with your changes, open your shell, go to the directory with build.xml script, type ant in the command line and press Enter. You will find the build results in the dist directory.
- Please note, that by default the applet will be signed with a test certificate. If you want to use your own certificate, replace the signJarKeystore.jks key store file with your own key store. The default value for the key alias and key password is signJar and can be changed in the beginning of build.xml script.
DigiSigner Applet has many configuration options that let you hide buttons, remove GUI elements or define
default values for signature parameters like time stamp server settings, hash algorithms etc.
If you need more configuration options please contact us
and we will try to help you.
How to specify a configuration option
The easiest way to specify an option is to specify it as an applet parameter directly in your web page. If you take a look at the source code of the web page with the applet you will see the following:
<script src="http://www.java.com/js/deployJava.js"></script>
<script>
var dir =
location.href.substring(0, location.href.lastIndexOf('/') + 1);
var archive = dir + "DigiApplet.jar";
var attributes =
{code:'DigiApplet.class',
archive:archive,
width:930, height:800}; // applet size on web page
var parameters =
{java_arguments:'-Djnlp.packEnabled=true',
// PDF document to open
digisigner_inputUrl:'http://www.digisigner.com/DigiSigner.pdf',
// hide zoom in button
digisigner_zoomInToolButton:'false',
// hide zoom out button
digisigner_zoomOutToolButton:'false',
// ... more options
};
var version = '1.6.0';
deployJava.runApplet(attributes, parameters, version);
</script>
The most interesting part are the applet parameters that start with the digisigner prefix. These are the options that control applet's appearance and behavior. You can add them or remove them as you want.
You can also set option in your Java code. Here is an example:
DigiOptions.setOption(DigiOptions.TIME_STAMP_SERVER_URL, "http://my_time_stamp_server.com"); DigiOptions.setOption(DigiOptions.TIME_STAMP_SERVER_ACCOUNT, "login"); DigiOptions.setOption(DigiOptions.TIME_STAMP_SERVER_PASSWORD, "password");
In the following sections you will find the list of options that you can use to configure DigiSigner Applet
Server part
As a part of DigiSigner Applet distribution we deliver also a simple server, which can accept signed documents and save them on the file system. The server is located in the server directory. To start it just execute the corresponding script: startServer.bat or startServer.sh.
The script has several parameters that you can change according to your needs:
-Ddigisigner.serverPort - server port
-Ddigisigner.webRoot - path to the web application that accepts and saves signed documents
-Ddigisigner.outputDir - where the signed documents are saved
The full code of the web application is also delivered and available under server/webapp/src. You can build it using the build.xml script. Feel free to use the code as a base for your own server implementations.
To specify to which URL the applet should send the signed documents you should use the parameter digisigner_outputUrl. See the next section for more details.
Input/Output Options
Options to specify what PDF document to open by applet's start and to what URL to send the signed document.
| OPTION NAME | TYPE | DESCRIPTION |
|---|---|---|
| digisigner_inputUrl | URL | URL of the PDF file to open by applet's start |
| digisigner_outputUrl | URL | URL to where the PDF file will be sent right after signing |
Here is an example:
// PDF document to open digisigner_inputUrl:'http://www.digisigner.com/DigiSigner.pdf', // where the signed PDF document should be sent digisigner_outputUrl:'http://www.digisigner.com:8080/saveDocument'
Please note, that the parameter digisigner_outputUrl should point to some server, which is capable to accept and save the signed document.
