Signing pdf signature field with hashed cert in itextsharp -


I have a hash of a certificate using the example and use it to fill the signature field in a PDF form Do anyone with ITextSharp have any examples or know how? This is a web app and the only way I can get to capture a sign from a smart card to a local customer.

You do not use a hash of the certificate to sign Can do Signing is done using the private key (and is not intended)

For the web application you have two options - either transfer the whole document to the client, or use some distributed signature mechanism Do not include client-side modules (either browser plugin / Java applet or standalone application).

Our company has developed a distributed cryptography add-on for the SecureBlackbox, which is described in the description and in the answer you need, the plan explains how the distributed signature will work.
