Here we have a piece of seriusly injured code, thank heavens we have the comments so we can repair it!
#!/usr/bin/perl -w
use strict;
$_ = "A silly obfuscation:"; # Something to start with.
$ # A buck for your thoughts?
0=0 # Yes, obviusly it is...
;$ # Got it backwards?
_="utaohrpr akr"; # Special variable, filled with gib
+berish?
map # Sure could use one here.
{$,.='$'.++$0.$_} # Anonymous Hash?
split # I'm about to...
'' # An empty string?
;$ # Again?!
_= # The gibberich here?
"Dog and Pony" # Hey, that is me!
;$"=" # Can you quote an assignment?
Js nte elhce # Barewords allowed?
";$" # Interpolating backwards var?
=~s # For my tilde POD?
/ + # \w* ?\w* ?\w* ?\w* ?\w*\?//g;# Division plus a match inside '#'s
+?
;s # Oops, should be a dollar, not 's'
+?
/$_/ # Matches itself?
$"/ # Unterminated String constant?
;s # Same mistake again?
/ + # \w* ?\w* ?\w* ?\w* ?\w*\?//g;# Vaguely familiar....?
$0=".";$" # Program is now current dir and ou
+r special var?
=~ # Another, but empty tilde POD?
s/($0)/($1)/g; # Replacing our program with itself
+?
eval("s/\n$\"/$,/"); # Always, always use an eval in an
+obfu! :)
print; # Now, what did we get...?
This is also my very first real try at something like this, so I am a bit anxious to hear what you all think?
