How to sign pdf from external application

[Speakearme@adobeforums.com]

Hello,

I’m looking for the method to sign a PDF file from external application.
First I looked for a library. But actually I’m trying to do this work with the tools of Adobe SDK.

I use the actual version of acrobat reader and adobe SDK (version 9).

I would sign a document without acrobat reader running.
I prefer not include a plug-in. That’s it will run with the default Adobe Reader’s installation.

I’m reading that is possible call a piece of JavaScript from C++ o Visual Basic with the “AFExecuteThisScript” function.
I hope that it will be a good solution, but I’m not sure.

Another solution may be use the API Headers (SDK 9) to make Plug-ins for make my application?
Can I use PubSec or DigSig to make a digital signature from a program? Not included in Acrobat Reader!

It is another solution that I found: (Unfortunately for the version 5.05 of Acrobat Reader and I’m not sure that it will run well)

At the moment I not want use Adobe LifeCycle for this work.

If you was involved with a similar project or have a product, please contact me.
Thank you.

SPECIFICATIONS OF OUR PROJECT:

We need to make an ActiveX program to enable our customers sign PDF before upload it.
The ActiveX program have to run through the web browser, so We are looking for a small DLL (Without dependences with .NET Framework or Java virtual Machine), it have to run own-self. It will have to add one or multiple digital signature at PDF file. The digital ID could be stored in a token device or in the store of windows. So, the library will have to "speak" with the csp (Certificate Service Provider) to sign the certificate.
I could use the CAPICOM to allow our customers select a certificate from a pop-up window. Then I need your product: For example a method or function that with INPUT
(1) PDF file to sign
(2) An ID of the certificate selected by the user.
Then result will be the "Input PDF file" with the digital signature added.

If you have this product, we are interested!
Regards!

Adobe Reader does NOT provide any APIs for this type of function.

Adobe Acrobat, however, does. These are the types of things that a paid for product gets you...
