Scripting...I love weakly typed languages :P

Hi fellas I was a bit busy these few days. I was trying to get the basics of Scripting and i have been pretty successful. So here's my first UserScript for mozilla for the site This little script lets you select all the checkboxes on the report page for quick deletion. Have fun :)

// Use this tiny little script to select/unselect all reports on the reports page
// of travian so that you could delete them quickly.
// ==UserScript==
// @name SlectAll
// @namespace
// @decription "Select All" reports on the page with a click for deletion.
// @include http//*.travian.*/berichte.php*
// @include *.travian.*/berichte.php*
// @email
// ==/UserScript==
// *********************************************************

var nbsp = document.createTextNode( "\u00A0" );
var newChkBox = document.createElement("input");
newChkBox.type = "checkbox"; = "chk_box";
var chkBox = document.getElementsByTagName("input");
for(i=0; i
if(chkBox[i].getAttribute('type') == "checkbox")
if(chkBox[i].getAttribute("id") != "chk_box")
if(chkBox[i].checked == true)
chkBox[i].checked =false;
chkBox[i].checked = true;

//CheckBox Text
var newTxt = document.createElement("b");
newTxt.setAttribute("style","color: #00CC33;");
var chkboxTxt = document.createTextNode("SelectAll");

//target Button
var trgtButton = document.getElementById("btn_delete");

//insertAfter Function.
function insertAfter(newElement,targetElement)
var parent = targetElement.parentNode;
if (parent.lastChild == targetElement)

//Lets Roll Baby

Obnoxious Schemeing :P(Brute Forcer in Scheme)

Aah the woes of BruteForcing!!! I was racking my brain for some time to code a very nice bruteforcing algo. I had some ideas but they were all messy so had to stop. Finally i found one googling. It was awesome simply awesome. It was written in c# and i thought I too should get an implementation of the same in some other language that has not yet been implemented. So here's my shot at Fame :P.

I am in love with scheme. To me its the best language where you can understand looping(The thing we take for granted thanks to the For Loop). Its also the best language for understanding recursion. Recursion in scheme is simply superb!!!! So here's a little implementation of that awesome bruteforcing algo in scheme translated by me.

(define sb "")
(define charlst '(#\a #\b #\c #\d #\e #\f #\g #\h #\i #\j #\k #\l #\m #\n #\o #\p #\q #\r #\s #\t #\u #\v #\w #\x #\y #\z))
(define (Start length)
(let loop([i 0] [max length])
[(= i max) (IterateChars 0 sb length)]
[else (set! sb (string-append sb "a"))
(loop (+ i 1) max)])))
(define (IterateChars pos sb length)
(let loop([i 0] [max 26])
[(= i max) (display "")]
[else (string-set! sb pos (list-ref charlst i))
[(= pos (- length 1)) (display "\n") (display sb)]
[else (IterateChars (+ pos 1) sb length)])
(loop (+ i 1) max)])))
(Start 4)

In order to change the the length of the string just change (Start length) => length to desired choice. I must simply say that anyone who wants to understand Looping and Recursion better should give scheme a shot.

skNiNe9's SKCrackMe #1

Its a Java crackme. I am trying to learn java so i gave it a shot. It uses DES encryption in ECB mode or rather DES decryption to verify the serial. This as how DES can be implemented in java.

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;

public class DES
public byte[] getDES(byte[] inputbytes, byte[] keybytes) throws Exception
SecretKeySpec key = new SecretKeySpec(keybytes,"DES");
Cipher cipher = Cipher.getInstance("DES");
cipher.init(Cipher.ENCRYPT_MODE, key);
byte[] cryptedTxt = cipher.doFinal(inputbytes);
return cryptedTxt;
public byte[] decryptDES(byte[] inputbytes, byte[] keybytes) throws Exception
SecretKeySpec key = new SecretKeySpec(keybytes,"DES");
Cipher cipher = Cipher.getInstance("DES");
cipher.init(Cipher.DECRYPT_MODE, key);
byte[] decryptedtxt = cipher.doFinal(inputbytes);
return decryptedtxt;

Have fun implementing DES :P

br0ken's What is my password?

Aah its  been sometime since br0ken put a crackme. I missed his last one my net connection was out then :P. br0ken's college has been keeping him too busy these days :P. It was a fun crackme. Made me do some math in a long time,  also i had to dig in a bit to remind myself the Gauss-elimination, Newton Raphson , Gauss-sidel iteration methods that i learnt for solving liner equations. You guys can have a look at br0ken's password once the solution gets approved. Cheers and happy cracking.

Aah! finally a lvl 4 crackme. Special features: a no good dll has been added :P. Gold Medal to anyone who does it before Indomit :) A step by step visual keygen will be most appreciated. Multiple keys for each name mayb possible but not a neccesity.

Have Fun Cracking It.

The latest addition to my crackmes. This one is simpler than my last two crackmes. The objective is to get the success message. Have fun Cracking it.
