Hi,
I am trying to sign the pdf with the program sample given under heading: How
to sign with an external signature dictionary (authenticatedAttributes
example) at the following url:
http://itextpdf.sourceforge.net/howtosign.html
But when i am opening the pdf then i am getting the ? mark in the top. And
it says that :
" the validaity of the document certification is unknown. the plug
in required is not avaialble."
So, which plug in it is talking about? I am using the Adobe 8 version.
One more quick query that at the same URL as mentioned above following
constants have been used,
*ADBE_PKCS7_DETACHED, SELF_SIGNED, WINCER_SIGNED. *
**
*So, in the api's, i am not able to find the meaning of these constants.
So, please send me the resource links where i can read the meaning of these
constans.*
**
*Just informing you that I have to use LUNA as hsm and keys, certificates
will be stored on it. Pleas suggest me that which will be the best way to
sign/certify the PDF as there are so many heading present in the URL
mentioned above. *
Thanks
Gurpreet Singh
