Stephen Hendrix commented on PDFBOX-2456:
-----------------------------------------
Supporting documentation for not decrypting the encryption dictionary from PDF
reference 1.7
(http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_reference_1-7.pdf):
"Unlike strings within the body of the document, those in the encryption
dictionary must be direct objects. The contents of the encryption dictionary
are not encrypted by the usual methods (the algorithm specified by the V
entry). "
> create TestSymmetricKeyEncryption.java
