it can open and save encrypted PDF file now(ver 2.9.0 or later).
but it can't encrypt PDF file that not encrypted by java.

The return of public int Open( String path, String password ) method in Document.java in line 326 maybe -2:unknown encryption.
I want to know, which encryption type it supports now(ver 2.9.0 or later).
whether we should just open files as normal, the sdk will check the encryption type.

just "Standard" filter can be supported for java.
which defined in "Encrypt" entry in trailer dictionary.
