Hi

I'm new with digital signatures and PDF.
I have developed an application based on .NET 2.0 that consists of a
webservice and a client application.
On the server side, using iTextSharp library, PDF files are
automatically generated as a result of client users' actions.
All ok.

The complicated part follows.

The documents must be digitally signed by both the client and the
server applications.
Each user that will work with the client application has an eToken
(Alladin) that should be used to sign the document.
The document is then passed over the net to the webservice and the
webservice has to apply another digital signature to the document.

The deadlock follows.

Using iTextSharp to sign the document I figured out that the only
solution is to use a PFX file and a password.

Not really, see http://itextpdf.sourceforge.net/howtosign.html#signextitextsharp2.
