Dear all,
I hope that I put the question in the right one category.
I have two encrypted PDF files - the one is 128 bit encrypted and processed fine. The other one is 256 bit encrypted and can not be handled (I get the error "11 (file is password protected or encrypted)" . Both files have property "page extraction" set to "not allowed". So I would expect that the extraction of content should fail for both documents. Why does it work in the case of 128 bit encryption?
Thanks and best regards,
Mikhail
