Encrypted PDF document 2006-08-14 - By Sergey Kling

Hello!
I use iText for the development, but have collided with one not clear moment:
I shall admit have the encrypted pdf document and we wish to receive
the information on its internal structure without extraction of its
contents.
Under specification PDF of a format at enciphering information about
structure of the document remains opened, but at use iText (when we
simply for example receive the dictionary) there is a mistake: "Bad
user password".
Whether there are any ways of the decision of the given problem?
I shall be very grateful to you for any recommendations.
P.S. It is meant, that user and owner passwords to us are not known, I
need to define only presence in pdf a file of some opportunities pdf's
format

Best regards,
Sergey V Kling
