Tilman Hausherr updated PDFBOX-2456:
------------------------------------
Attachment: PasswordSample-256bit.pdf
I'm expanding the test to process three files prepared by [~msahyoun], to check
that permissions are treated correctly. In the attached file
PasswordSample-256bit.pdf, there was a padding error in Object 38 (an XRef
stream) with the old parser. This is another Adobe documentation problem, in
the encryption segment it isn't mentioned, but in the File Structure segment,
one can read this: "The cross-reference stream shall not be encrypted". Thus
we'll skip that one.
> create TestSymmetricKeyEncryption.java
