Thanks for answer.

as to Q1:
https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf
https://www.iso.org/standard/63534.html

and to Q2:
I need to validate PADES signature in PDF file, so this is related to PDF.
Unfortunately QuickPDF do not have support for PADES signatures, for checking and for signing.

So for now, I must maintain this by my self.

Regarding "question 2"...
It's not a real QuickPDF-question but... ;-)

openSSL should feed your needs?

Hi Michal,

regarding "question 1" there isn't a real download-link.
A bit strange for a free and open file format but...
The new documented specification is only available as a paid download:

I read "PDF 32000-1:2008"
First Edition 2008-7-1

Question 1: Maybe you have a link to recent version ?


Problem:
in:   Table 252 – Entries in a signature dictionary
Key: Contents

"For public-key signatures, Contents should be either a DER-encoded PKCS#1 binary data object or a DER-encoded PKCS#7 binary data object."

Question 2:
How to decode "DER-encoded PKCS#7" to human readable form 

Something like in this following example:
