Answer to How for beginners of SQL Injection

If I ask you one question to what SQL injection is, your answer will be either I don’t know or I know. Now my question for those who say I know is? What do you really know about SQL injections? You may say it is a way for an un authenticated person to get access of system without having any kind of login credentials. Now if I will ask how? You may say it’s easy; I will just enter following code in login box instead of entering valid proper login details

Username as a’or’1’=’1 and password as a’or’1’=’1

Now I will ask you do you know what you are doing here. Now confused  :).No Problem, here is the chance for you to know about this

When you open a login page , you enter your login information , now the Web applications access databases to match this information in its database table , if it matches then it will provide you  the access of  system else it will display you error message

In order to access database an application fires SQL Query in the following form

Select * from users where username = xyz and password = abc;

Here we are passing xyz as arguments that you have entered in username field and abc as password, it is like a condition that whether there exists and data with username = xyz and password = abc. Now in SQL Injection what you are actually doing is manipulation of this SQL query.
When we enter username and password as a’or’1’=’1 , it makes the condition “where username = ‘’ and password  = ‘’ “ true since a’or’1’=’1 is always true , hence condition will be satisfied and it will provide you access of system, but it will only provide you access of any random account , if you know username then you can enter username  and password as a’=’1’=’1 , it will give you access of account of desired username
This is commonly known as Blind SQL Injection.

So with this i will complete my post, in next part we will explore it further, if anyone having any confusion regarding this ,then feel free to ask

Introduction of Jquery and its use in cakephp Applications

The day Tim Berners-Lee invented WWW AKA World Wide Web , we have seen a lot of changes in the way we present information through internet . Today if you visit a website, you will see a lot of special effects that adds a lot to look and feel of website . Have you ever wondered how these effects can be implemented in a webpage?
No? Not a problem , here is the chance for you. You might have heard about javaScript which is used to make webpages interactive, but it was not that much effective , So web developers provide a  new library named jQuery  is designed to change the way that you write JavaScript. It is also fast and concise

Now Let us now learn how to use it in cake applicationYou have to first download it . You can download it from here . Then you have to put it in js folder of  your webroot directory inside app folder of your cakephp application.

In order to use jQuery Special Effects, you have to include it in your view or  ctp file using following syntax

echo $this->Html->script('jQuery');

Note you have to make sure , that name of jQuery file should be "jQuery.js", otherwise it will not work on Linux server.

 
Look us now start with some scripting
The Basic syntax used in Jquery is $(selector).action()

• A dollar sign basically mean getElementBy
• A (selector) to "query (or find)" HTML elements
• A jQuery action() to be performed on the element(s)

<script type="text/JavaScript">
$(document).ready(function(){
// This line is used to prevent execution of script until page load
 $(".hide").click(function(){
       $(".manish").hide("slow"); // hides all elements with class="manish”
      });
 $(".show").click(function(){
         $(".manish").show("slow"); // Show all elements with class="manish”
  });
}) ;</script>

Now we will do some css part . You have to create a new css file with any name of your choice and write the following code in it.
 

div.manish  {
  width:300px;
  background-color:yellow;
  padding:7px;
  border:solid 1px #c3c3c3;
  }

Now include it in css folder of webroot directory and then include it in your webpage using following syntax

echo $this->Html->css('style1');

Now its time to create some button on which you will fire events such as hide, show using cakephp syntax

echo  $this->Form->button('hide me', array('class' => 'hide'));
echo  $this->Form->button('show me', array('class' => 'show'));
 <div class="manish">
     <p>
    <span style="font-family:arial;font-size:14px;">My name is Manish Kumar Goyal
      I am a computer Engineer</span>
    </p>
 </div>

So with this we are done, this is one of the most basic explanation of Jquery , if still have any kind of query. Feel free to ask

Nmap : Fist step of hacking

Nmap stands for Network Mapper. Nmap was designed to be a free utility for network exploration or security auditing. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use.It was designed to rapidly scan large networks, but works fine against single hosts.

Let us take a simple scenario to learn more about nmap

Say a a thief wants to steal something from house , then as a very first step,  he wants to find the location from where he can get himself into house, similar to that nmap performs same thing for you. It scans all the ports(It is a entry point in simple terms) where a host is listening ,and lists them 

In order to scan a host you have to perform following steps
1:- Open CMD prompt
2:- type nmap.exe -sS -F <hostname>


Press enter , it will lists all the port where a server is listening

How to add a timer using Javascript in a webpage?

Have your ever taken an online exam , you might have seen a timer where after appropriate time it automatically submits the form and redirects you to next page, today through this post , I will explain you this whole functionality in detail

Here we need 2 things

1: Simple HTML form :- 

We will create a simple html form with one question , 2 radio buttons and a submit button, it will look like this

<form name = “question” action = “next.php” method = “post”>

1:- What is Chemical name of hydrogen?

<input type = “radio” name = “ans” value = “Hydrogen” >Hydrogen

<input type = “radio” name = “ans” value = “Helium” >Helium

<input type = “hidden” value =”1600” id  =”hdnTimer”>

<input type = “submit”>

</form>

2:- Next comes script part , so here is your script

<script type = 'text/javascript'>

function MyTimer() {

var valueTimer = $('#hdnTimer').val();

if(valueTimer > 0){

       valueTimer = valueTimer - 1; 

       secs  = ((valueTimer % 3600) % 60).toString();

       if(secs.length  == 1) secs  = '0' + secs;

      $('#idTimerLCD').text('Time Left :' + secs + ' sec' ); 

       $('#hdnTimer').val( valueTimer ); 

 }  else {

       $('#Question').submit(); // Submit form as soon as timer complete

}

}

// This is used to call MyTimer() as soon as body loads and after every 1 sec

$("body") . ready(function(){

setInterval( "MyTimer()" , 1000);

});

</script>

Note here i have used jquery , so you need to download it from their official site and add it to your page

So this is what you all need to add a timer in your application , now enjoy , if still have some query , then feel free to ask :)
