Adobe interactive forms digital signature

Hi to all,

I'm try to get digital signature data from a signed PDF generated with Adobe interactive forms.

I want to know only if the PDF is signed or not. For the moment I'm not interesting about the CA.

When I call metod set_task_getsignatures a cx_fp_runtime_usage exception is raised.

If I try to test this operation with sample program FP_PDF_TEST_12 the following message is shown:


- SECURE ADS connection: "SYSTEM ERROR: com.adobe.ProcessingException: com.adobe.ProcessingException: GetSigatures require a secure connection. Please install the high encryption PDF Manipulation service and enable SSL."

I found a note ( that spoke about this problem.

Is this the only way for knowing if a PDF is signed or not?

Best regards,
