Being unfamiliar with the beginners@ list but having
stumbled upon this thread on a web archive, I thought
I'd reply, for what it's worth. A few years ago, I
wondered this same thing and came up with the
following:
http://www.dfw.net/~scottvr/Filter_decrypt_crack.pl.txt
It's a fairly long commentary on it so I won't post it
here, just the link.

One trivial way is to add -MO=Deparse to your
invocation line:
perl -MO=Deparse your-proggy-here
That'll be a decompilation of the bytecodes. To
actually get the
original source requires a few-line modification of
the source of your
Perl, but that's for another posting. :)
I'm not sure if I should post this to a beginner list,
except to warn
you that any attempt to encrypt your source is
therefore trivial to
back out, and this is by design. :)
