Platform independence and digital sign

[Juan Fco. S.]

We are interested in users validation and documents signing using digital certificates on our web site. Our target users could use any type of browser or operating system, therefore we want to know if there exists a piece of software that could access browsers keystores or choose a certificate from the harddisk to validate and sign documents.

I have seen a commercial solution that fulfills these features. It is base on a java applet. The problem is that they don't lincense their product, they just sell projects construction on demand.

If you know any free solutions, please let me know.

So far I have found these references:

� Java Library for accessing Microsoft Keysotre (using JNI):

� Article by Svetlin Nakov about signing documents with Java Applets (in his personal web page you can download an implementation):

If you want to authenticate a user over HTTP by using a certificate, you need to import the certificate into the browser. All browsers support that.

Maybe you can explain in more detail where the documents you mention fit into the picture, and how they interact with the web site.
