    Sign PDF Documents

    Madhukar

      Hi All,

       

      I have developed a smart card mini driver for  a smart card and able to sign office documents. Now, I'm trying to sign a PDF document. To do so I'm using Adobe Acrobat Professional 11. When I try to sign the PDF document by clicking "Sign" button and when I debug my mini driver I see the document is try to sign using SHA-256 algorithm. However, the smart card and the mini driver developed only supports SHA1 algorithm.

       

      How can I over come this problem. I have few questions here:

      1. Is there a way I can make the Adobe Prof 11 to use SHA1 algorithm?

      2. Do I need to develop an Adobe plugin so that it uses SHA1 algorithm to sign? If so, can I get some documentation?

       

      Thanks and Regards,

      Madhukar
