How to automatically validate (a)...

I'm currently trying to automatically validate all the signatures on a pdf (so that you see a green V instead of the orange questionmark) and than convert this file to a image-pdf (nothing on the pdf is selectable).

I'm trying to do this via the adobe acrobat sdk but i don't know where to start. Can anyone help me out here or give me a sample / ...

the goal is to have this running on a server (all the certificates (ex. belgian root certificate, ... will be installed on the server)

regards,

P.

Hi,

As you want this to work on a server you will need to select a different approach as the Acrobat Application is not supported in server use (and it would likely display dialogs which would stop Acrobat until they are dismissed.

I would recommend looking into the Adobe LiveCycle product.

Hello,

this looks strange to me. I would expect that using the Adobe SDK, we would be able to write programs to run on a server.

so, maybe i was not entirely clear in my question

can i open a pdf with de sdk (in background) and convert it to a tiff file having the signature a green V instead of the 'validity unkown' or 'not verified sign' (?)

i have read things about the DIGSIGHFT and a certain PubSec-api but is this the way i should follow ? Does anyone maybe have a simple example in c# ?

regards


Hi,

The Adobe Acrobat SDK is just a collection of header files, samples and documentation that require Acrobat to be installed on the machine you wish to use the Acrobat SDK on.

This means that any solution you create requires Acrobat to be installed so therefore you have to abide by the Acrobat products license agreement. If you want to do this on a server then you need to look at other options of which the LiveCycle suite would be the most suitable from Adobe.

To answer you direct questions.

I believe the conversion to TIFF is possible and you are able to validate the signatures using the SDK, however you may not be able to make sure that the application remains in the background while it is doing this process and it is against the license agreement to run the Acrobat application on a server.

Hope this helps your understanding

If you read the material that comes with the SDK, it clearly indicates that ''Adobe Acrobat is not licensed for use on a server, nor is it technically suitable''. No questions there.

If you wish to do server-based processing of PDF using Adobe technology, then we offer our LiveCycle ES family of products...


As far as using the SDK (on the desktop) to convert to TIFF - yes, that is fully supported. You can also use it to verify/validate signatures.

HOWEVER, the ''green check'' is NOT part of the page content and therefore will NOT appear on your raster image.
