Hi All!

What I want to do is adding a PKCS#7 signature to a pdf document. This 
signature is generated by a PKCS#11 Library, so I can work with an 
external card reader. It is not possible to get the private 
key/certificate out of the card.

What I understood from now I have to

1. open a pdf document in itext
2. calculate a hash from this file
3. Generate a PKCS#7 signature with the PKCS#11 Library
4. Add this signature to the pdf

I already read the tutorial about adding external signatures under 
"http://itextpdf.sourceforge.net/howtosign.html";, but that doesn't help. 
They always work with keys and certs which I can't access.

So please help me. Java Code would be the best, except for point 3 of 
course.

Thanx in advance,
Chris
