Digital Sign PDF file SSF01 test

Hello ABAP gurus,

I'm trying to add digital sign to a PDF running the SSF01 report.

I'm using the standard certificate for test and my parameters are:

Signing                            X

SSF format                      PKCS7

ID                                    CN=DD3, OU=I0020478421, OU=SAP Web AS, O=SAP

SSF Profile                     SAPSNCS.pse

Password

Input data                             C:\Users\in.pdf

Output data                          C:\Users\out.pdf

Security product (only AS)   SAPSECULIB

Hash algorithm                    SHA1

SSFEXP                              NOCHECK

SSFSREXP                         NOCHECK

The output PDF is created and have more line than the input one, some at the start and the others at the end, but I can't the digital signature when I open the PDF.

There is something that I miss?

Thank you for help,

Pasquale.
