Hey Tim, Even compiling it isn't enough. Its just as easy to use a decompiler and then process it through some of perl's own back end translator routines ( -M0=Deparse etc) which can even de-obfuscate the code to some degree. Although its better than doing "nothing", its not a far leap to get to the sources from this stage with Perl. I think following your thoughts at the end of your post (in looking for alternatives) is a better way to go once we understand what Charles is wanting to accomplish.
True, I've heard this, though I've not tried to do much in the way of this method personally (I never had a reason to). I did test some stuff before and didn't have much luck, but I only spent a few minutes on it, so it's not surprising I didn't have any luck with it. Even so, depending on what Charles wants, as we agree, someone could just perhaps use strings or something to get the information that they want. As for the obtaining actual code, could you do me a favor and provide me with some specific information? I'd like to test some theories I have with that to see what I can do, or deny people _from_ doing. Maybe it'll work. :-) -- Regards, Tim Greer chatmaster () charter net Server administration, security, programming, consulting. --------------------------------------------------------------------------- Evaluating SSL VPNs' Consider NEOTERIS, chosen as leader by top analysts!
