protected and encrypted security

I also have the same issue: I am encrypting my file using AES 256 algorithm. But when i try to execute the Document.open(path, password), I am getting "-10:// access denied or invalid file path" . Although my password and file is correct.
can anybody tell me , am i doing right? Or there is any other encryption algorithum that is supported by the PDF reader?

Please reply!!!!

may you send us sample file to:
[email protected]

I have mailed my sample file that i use for encrypting the file that is being downloaded from a url.
Please check mail

AES256 use 128 bit as block.
so, 16 bytes, for each group.

Yes I am using the same block for the encryption/Decryption

plz wait next version.
there are 2 new classes:
--com.radaee.util.PDFAESEnc
--com.radaee.util.PDFAESStream.

and PDFEncAct show how to using these 2 classes.
