What is "Free" isn't always "Free".

Read about Adobe & Gnash development.

Earlier I was having problems with finding a good 64 Bit Linux Flash or Acrobat, although that may be resolved for now.

Also, when I want to view a PDF, I just want to view it.  Perhaps rotate a few pages or something.  The last time I used Adobe Acrobat, I was getting annoyed with all the "Extras" that Adobe was adding.  I think there was also "nag-ware" to try to get people to buy the commercial version.

It seems a bit of a pointless exorcise hunting for a non adobe decrypter when a free adobe one is available

You described Adobe as "small", but it expands to about the same size as my Linux operating system.
I was looking for something more lightweight, less bloated, and possibly with more features and better security against malware, (like Foxit Reader)

... if you have one please publish it.

If I find one I will.

FoxitRead seems to be the answer it opens files produced by Adobe Acrobat 256 bit encryption no problem.

None of the first 4 choices of pdf reader that I tried on Debian Linux could open the Marchese document.  Adobe did seem to be having problems with the implementation of standardised 256 bit encryption

RD, if you're using Linux http://en.wikipedia.org/wiki/Xpdf might work for you. STDU viewer does not support encryption it seems, although it recognizes it? And that one is window btw

And ask for a password too???
Either it supports encryption and then the Adobe is non standard, or someone might have planned to support it?? Awwhhhhh..
