Signing a PDF file

[Former Member]

Hi all.

I want to sign a pdf file.

1.- u2019ve generated the PSE file in my system and Iu2019ve validated it. Iu2019ve inserted my certificate in the pse file.

2.- Iu2019ve created a program how converts a spool to PDF format (FM CONVERT_OTFSPOOLJOB_2_PDF ).

3- I use the FM SSF_GET_PARAMETER to get my pse parameters.

4.- I use the FM SSF_KRN_SIGN_BY_AS to sign the pdf data. This FM generates a signed data in binary type.

5.- I Verify the signed data with FM SSF_KRN_VERIFY. The validation is good.

6.- I generate the pdf and download it with FM GUI_DOWNLOAD. I use the binary signed data ( Generated in FM SSF_KRN_SIGN_BY_AS ) in this FM.

The problem is with the pdf generated. I can open it and I can read it without problems but I donu2019t see the sign in this document.

The pdf document signed is with un 1Kb more than the pdf not signed ( there are more information ) but the sign not appears .

I'm using SAPCRYPTOLIB and my SAP version is 4.7

Can you help me , please??? What is my error ??

Thanks a lot.

Ismael

Thanks a lot.

But this not solve my problem.

I've read a lot of information about this, and I've test the sign FM, but only need to save the pdf file with signature and I

save it but without the signature.

Some ideas???

Thanks

Hi Ismael,

Did you solved your issue? Looking the posting date, i suppose yes.

Can you tell me how you did it?

Thank you
