I assume this patch is against the version before I made my changes, because it
gets refused ("Cannot apply hunk"). However both of your files get opened and
read with the current code. But don't worry, when it's all done I'll also have
two test files created not with PDFBox to make sure that the code is good with
files without the length entry.

> Follow-up of PDFBOX-4413. AES256 works for public key crypto, but AES128
> doesn't when the file is generated by an external software. (local tests
> work) We should at least get the decryption to work.
