Martijn Brinkers commented on PDFBOX-872:
-----------------------------------------
The exception is thrown because the PDF was encrypted with AES. PDFBox does not
yet support AES out of the box. I have added a patch to add AES encryption to
the SecurityHandler. AES is enabled in the StandardSecurityHandler when the
PDCryptFilterDictionary says that the PDF was encrypted with AES.
With the patch, the attached PDF can be read.
