> Well... this is actually *not* a PDFBox bug, but an Adobe Distiller (7.0.x) one...
> The following exception is thrown in StandardSecurityHandler.computeEncryptedKey:
> org.apache.pdfbox.exceptions.CryptographyException: Error: length should be 5 when revision is two actual=16
> The PDF file is accepted by various readers and contains the following object:
> 2106 0 obj
> << 
> /Filter /Standard
> /V 1
> /R 2
> /Length 128
> /P -12
> /O (f¥—èàã؇�æa§�»eücmý/Æ6ïàY÷[*™6)
> /U (å£átÂ>c÷sÉcû^KÞ•À›¶YjCò~)
> >>
> endobj
> Referenced by an encrypt tag:
> /Encrypt 2106 0 R
> PDFBox rejects (rightly) such an object with version 1, revision 2 and a length != 5*8
> That said, we are parsing many of those files to feed a Lucene index. Could the validation be relaxed ?
