Question Hacking pdf files


Who knows what does PDF files do for it's security. For example there are some PDF files which can not be copied (mark), or can not be printed. Is it a gentle way for PDF readers that they do not allow to be printed or PDF uses a way that it can not be printed?

Well, if you can render the PDF at all, it's printable. It just may not be printable using whatever API the PDF stuff normally uses. However, not respecting the "DRM" (*snicker*) built-in to the PDF may be a violation of the DMCA

there has once been a tool which allows to remove the security from pdf files, at least when it's only 40 bit encrypted, I think it's called "aebpr".

I heard that someone was able to open such secured pdf files in ghostscript.

Note: I can't tell you how to open them in gs and I can't send you the above mentioned programm because I don't have it !
