Re: Just another silly pattern

You have an "x" deliminated (did I just make that word up?) string ($d) of the output of

chr() - 1

on every character of your original code. And on that topic your original code is: {@a=("A(Whfg)","A(nabgure)","A(crey)","A(unpxre)");for (@a){s/\(/\"/g;s/\)/ \"/g;tr/A-Ma-m]N-Zn-z]/N-Zn-z]A-Ma-m]/;s/N/print/;$_.=";";eval($_);}} You take every element of @a and first turn the { into " and the } into a space and a " so:

A(Whfg)

becomes ( s/\(/\"/g )

A"Whfg)

becomes ( s/\)/ \"/g )

A"Whfg "

then you use tr/A-Ma-m]N-Zn-z]/N-Zn-z]A-Ma-m]/ to turn

A"Whfg "

into

N"Just "

this works because it replaces a character, for example W, with its complement (kinda broke explanation :) i.e. W is the 10th character in N-Z, and J is the 10th character in A-M, so J replaces W. It is case insensitive because you say both A-M and a-m, etc. Then

N"Just "

becomes ( s/N/print/ )

print"Just "

then ; is added to the end of the string by $_.=";"; and the string is evaluated! for my first explanation of a obfuscation, not that bad :)

Hehe. I didn't think anyone would actually go through it and explain it.
Yes, I admit it is a little obvious, but it was fun to put together.
