Hi. I am using some 3rd party programs to digitally sign and timestamp PDF file.
If I use one of the Polish Trusted Certificate Authorities (Non repudation certificate),
Acrobat Reader displays the error with message - "Uknown critical extension"
Because of that error Acrobat Reader can't make the certification path.
The id of this extensions is 220.127.116.11.18.104.22.168.3
(Here is the description) - http://www.alvestrand.no/objectid/22.214.171.124.126.96.36.199.3.html
This can be critical or non-critical extensions, which CA providers are allowed to use when generating qualified
certificates - http://rfc-ref.org/RFC-TEXTS/3739/chapter5.html
I am using the latest version of Acrobat Reader, Windows XP SP3.
Hope anyone can help.
With best regards
