1) use keylength 256 => AES256 will be used
it works.
But I get a warning.

Thanks, I got these too from time to time, but ignored them due to the
code comment "Relaxed to accomodate buggy encoders". However from your
text I understand that it happened with PDFBox. It is indeed a bug, due
to operator precedence rules. I will fix this in PDFBOX-1594 soon.
As a side effect my old Adobe Reader filed under Linux, that he is too
old. Since I have no Windows here, I then installed the Adobe Reader
under Wine. This makes it possible to open the PDF.
On this occasion I would like to see if you used as Owner password
null (new StandardProtectionPolicy(null, null, ap)), a PW is randomly
generated (as it does for example iText).
Sorry, I don't understand you. AES256 does have a random component but
this is a salt.
