I have a direct question but I am open for any better suggestion. I have an index file (bunch of numbers that don't mean nothing to me but are extremely important for my application) that is going to be transfered over the net. Now the best way to transport the info is as a txt file compressed with some compressing system. However, the numbers are somewhat important and I would not want everyone to look at them. So my options are to send them in binary format. But then I have a portability issue (especially with intel boxes). Is there a way to somehow encode (hide) the content of my txt file or is there maybe an alternative way of transport that i haven't consider yet. (yes and Perl modules if such exist would be of extream help ).
