Michael for the quick response.
Is there any way we can encrypt a pdf having signature fields in them?
I want the pdf which consists of signature fields should allow only printing

I can't think of a reason why it wouldn't work in iText 2.1.7.
I see that you've now tried using different passwords for user and owner,

iText only sets the bits, it's up to Acrobat to allow or not allow.

Hi Thanks,
Will it give the special markers for the updated page
(on the top corner). I think so. Right?.
Will it work same in all pdf editors?
Thanks

Hi Shashi,
you're on the right path.
- but in step 3. you should put placeholders in the
values /ByteRange and /Contents (e.g. zeros or whatever).
- after writing out the resulting PDF (step 4.) you should work
only on these placeholders, you don't need iText
any more (you must not use it
