PDF encryption on Linux / AIX

Hi all

I want to create encrypted (password protected) pdf files. Can this be done currently using PDFInclude on Linux and/or AIX?

We are using OpenEdge 11.2 (64 bit) on Red Hat Linux (also 64 bit), as well as Progress 9.1E (32 bit) on AIX (64 bit).

We have been creating pdf files successfully for years - but without passwords - using an old 2004 version of PDFInclude on both versions of Progress.

Hi Ezan This should be

Hi Ezan

This should be possible, but a small .so must be built (using the source code in the dll sub-directory, i.e. rc4.h & rc4.c) in order to have the rc4 function for Progress.
I never did this myself, but if you manage to do it I'm very interested in the steps you followed, in order to document it here.

On the other end, I have a new almost fully rewritten version of pdfinclude, which does not make use of an external dll/so library for encryption, only AES-128 (and does a lot more). Contact me for more information if you are interested.
