Hi, I get a mission on my job which needs to process the watermark and encryption on PDF. I need to build my own application, I use the PDF clown, it can help me solve the watermark thing. but I can't find any information that can help me on the encryption, I need to encrypt a lot of PDF, some of them can be printed, some of them need password to open, some of them..., can you give me some tips.
thanks a lot for your any advice. The clown is really good and help me a lot.
Thank you Jim.
I'm sorry but currently PDF Clown doesn't support any encryption facility at all : please look at some other project for such a functionality, for example iText .
