I am making a pdf viewer in a part of my program.
I'm trying to open PDF file by using PdfDocument API
It works fine in AES128 encrypt files or non-encrypted files,
but it fails to open AES256 bit password-encrypted file.
I have tried to open the aes256 pdf in edge and chrome browser,
edge failed, but chrome had no problem.
I think it is a problem of MS PdfDocument API.
Is there someone who had same problem or
someone who has solution?
