Silverlight PKCS#11 with JavaScript Interface

We worked a lot in the past months on NCryptoki, the .NET wrapper to PKCS#11 module and we worked a lot in finding the best way to integrate PKCS#11 tokens in a web page (aspx, php, jsp, etc.). Till now we used a Java based approach using a Java Applet embedded in the web page. Such an applet includes a Java version of NCryptoki (JCryptoki) and a JQuery script that supplies a JavaScript interface to JCryptoki's classes. Such a Java approach works as expected by has some not nice-to-have security issues that: 1) give a bad user experience; 2) are higly dependant on the JRE installed on the client side. So we searched for a better way. We ported the entire NCryptoki package to Silverlight 5 and we have created a Silverlight user control that exports the NCryptoki classes to the JavaScript world. This approach seems very nice respect to the user exeprience and doesn't give strong security issues.

As an example, below there is a PKCS#11 dump script.
