Hi Team,
      We have encrypted Editable PDF and our requirement is to fill that
editable pdf by preserving the same encryption.
  Approach :
  Step 1:


    - Read PDF File .
       - if encrypted  remove encryption


    -    pDDocument.setAllSecurityToBeRemoved(true);


    -  Fill the editable PDF using  *PDAcroForm*
       -  Save *filled editable  PDF*
    -  Step 2:
       - Read Filled editable PDF file.
       -
*Want add encryption/permission  same as original PDF  *
       - *save filled editable PDF with original *

*encryption/permission . *

   Can you please help out with this using Apache PDFBOX ?


You need to know what the original encryption was, and reuse the 
passwords (user and owner).

An alternative would be to use incremental saving, but this is tricky as 
it requires some knowledge of the COS model.

See the testSaveIncrementalAfterSign method in TestCreateSignature.java 
in the source code download.
