in reply to Retrieving hardware information through Perl

Perl is an _interpreted_ language. Anyone who can read/write the script can hack it to avoid your checking mechanisms. There's no use in copy protecting your scripts.
(No, perlcc is not the answer)

    In fact, I do not try to protect a Perl script but a Java application. Since Java does not really have any mechanism to access the hardware and create a key I was hoping to do it through Perl and pass the CPU ID or something like that back to Java. Any ideas? Thanks, Chris

      Perl hasn't got any native solutions to get hardware information.
      Under Linux, you can use the /proc filesystem, under Win32 I'm sure there's a win32api solution, etcetera.

      By the way, all that needs to be done to work around your so called protection would be changing the perl script, so embed it and encode it. Even then, it'll not be hard to work around it.

      Same goes for Java, as even .class files can be decompiled.

      see this page or this one for examples.
