Will I Hack Something New?

1 year, 2 days since my last obfu. Hope I'm not too rusty. :)

$q="WillIHackSomethingNew";

Self Criticism by jake (Pilgrim) on Sep 18, 2002 at 15:15 UTC
There are a few things I like about this obfu. But in general, there are a lot of things that bug me. The first being that it could have been a lot better. Let's start with the phrase "WillIHackSomethingNew". It seemed appropriate when I started, since I was kinda curious if I could. Plus I needed a sentence exactly that length. It doesn't exactly roll of the tongue. And I feel that this statement has no relationship to the rest of the composition. I like to have the process of the code resemble the output or the code itself. Like this obfu. I like the way I presented the content of @@. I wanted the source of my output (j.a.p.h.) to be obvious, while obfuscating the process for extracting the data. But the process is where I really have my issues. The control structures are way obvious. Especially the if statements. I basically do the exact same thing 4 times in a row. And there is nothing special about the while statements. The only thing that obfuscates these are things like using strange scalars (i.e. $:%$%==1) and embedding the control structures into one continious block of code. sub _ is right out! I am happy with two things with this block of code. It is almost completely solid, using only one unnecessary ' ' and ony unnecessary ';'. And I had fun with the first two lines: `;$;=$/=(1==21);$==$-=2;$=*= $==++$=;$.='';$$=$-;;while(` [download] I like the overall idea. I'm sure I will make a second attempt sometime soon. jake	[reply] [d/l]

I'm much happier with this than the original. `{$~="WillIHackSomethingNew" ;@@= ( ' u sj ' , ' ' , ' t ' , ' ' , ' e r a n ' , ' ' , 'p err e ho t' , ' k c ' , ' l ' , ' ' , ' h a ' ) ;$;=!1;$==$-=2;$==$==++$=; $$=$-;$}=$--1;$%=$$$-;$\|=! 0;$x=' '}while($~=~/(.)/g){ ;print$x x$-.substr($@[$;], $=,$\|);$:=ord($1); if($:%$% ==($%==$-)\|\|$}==$:%$%){$;+= $-($}-$:%$%);$=+=$-$:%$%; }$=-=$:%$%($:%$%==-$}+$%); $;-=++$:%$%($$+$\|==$:%$%)}` [download] I guess I was a tad rusty. :)	[reply] [d/l]

While i'm certain you can do much better, here's what my spin would be: `$q="WillIHackSomethingNew"; @@=( ' u sj ', ' ', ' t ', ' ', ' e r a n ', ' ', 'p err e ho t', ' k c ', ' l ', ' ', ' h a ') ;$==$-=$^F;$==$==++$=;map{ $..=substr$@[$;],$=,1;$;+=! ($_=(ord)%4)?$-:$_-$^F?q::: -3;$=-=/3/?3:/1/?-$-:q;;}$q =~m;.;g;print join"$\"$\"", $.=~/./g,chr++$;+$;++- --$\|` [download] hmm, that's probably easier to read. sigh* oh well, it was fun... jynx	[reply] [d/l]
