Hello,

I'm developing a class library for Signing PDF documents. In my interface i'm getting only two parameters. These are:

byte[] signPDF(X509Certificate2 signingCertificate, byte[] PDFContent);

In my class library i will get signing certificate so i don't need to read from smart card anything. When i didn't provide dll location to DigitalSigner it gives me null reference exception. 

As a result, I have one certificate and byte array of pdf file. How can I sign that pdf file ?

Thank you.

Thanks for your reply,
Before NCryptoki I was using iText for signing PDF files and I was sending related certificate and pdf bytes. As you said before, I have private key and related certificate. In other words, I don't want to use NCryptoki for getting private key and certificate from Smart card, I only want to sign PDF files with private key and certificate. Is it possible ? 

Note: I'm beginner in this area. I think, I want PKCS#7 signing.

Thank you. 

Thanks for reply, 

One more question, How can i use PKCS#7 with NDigitsign ? Do you have any example ? Because i didn't find anything.

Thanks...

Could you give me exact location in zip file ? I didn't find anything :(
