Ways To Be Anonymous Online :

2019-05-08T17:27:00.000+05:30

Hi do you want to be anonymous online to view blocked websites, protect your self from hackers or want to hack some one
and stay un-traced?. In the following post i will explain 4 easy ways by which you can stay anonymous online!

1. Using Proxies
A proxy is an address ( IP address ) of a Server (proxy server) that is placed between your computer and the Internet The advantage of a proxy is that your real IP address is Hidden so when you hack your giving the IP address of the proxy sever and not your real IP address Same way if your a normal Internet user the hacker won't get your real IP but the IP of the proxy server.You can use it to enter site or forum that you are IP is banned. To know more about proxies les me know above this post and I will post a full Tutorial about it.

2. Using Tor
Tor-proxy is a free proxy-server service that Internet users can use to hide their IP address while surfing the Web. Tor (The Onion Router) is free software for enabling online anonymity. Tor directs Internet traffic

Web developers/ Students don't save your plain password in the database. There exists a chance for HACKING!

2017-01-28T21:32:00.001+05:30

Web developers/ Students don't save your plain password in the database. There is a chance for HACKING!

Last week, I had checked a couple of companies website's source codes to shield them from hacking. It has been seen that, they are using plain password (as shown in the screenshot below) in their database. That is you can see the password of all registered users in the database using any database tool like PHPMYADMIN, SQLYOG etc. It can be noted that many users, using the same username and password for logging into multiple websites like gmail, onlinesbi etc. Thus hackers can easily enter into multiple website using your username and password which was stolen from a less secured website. So I recommend all of my readers to use different usernames and passwords in different websites.

Now we can come to our topic. From time to time, servers and databases are stolen or compromised by hackers all over the world. With this in mind, it is important to ensure that some important user data, such as passwords, cannot be recovered. In this tutorial , I will explain how hash technique helps us to escape from these situations.

What is "hashing"

Before the brief discussion we want to know that what is hashing technique. The theoretical definition of hashing is given below.

Hashing converts a piece of data (either small or large), into a relatively short piece of data such as a string or an integer.

Normally, all famous hashing algorithms are "one-way" algorithms means, it will convert your information (say password) into a string with some alphanumeric characters. md5(), crc32() etc are widely using hashing functions.

Hashing using PHP, An example!

In PHP, there are many built in functions for hashing and its format is very simple compared to other programming languages.
An example PHP hash function is md5(). Please use this code for md5 hashing

<?php
$info = "PravySoft Calicut";
echo "My information before md5=".$info;
$info_hash = md5($info);
echo "<br>My information after md5=".$info_hash;
?>

The screenshot below shows typical result of this code

From the screenshot, it is clear that the md5 function will convert the information into 32 character hexadecimal number (Number 0,1,2,3,4,5,6,7,8,9 and characters A,B,C,D,E,F). One hexadecimal character can be represented using 4 bits (ie 1=0001, and A=1010) thus md5 result set dimension is 128 bit.

You cannot reconstruct the original information (pravysoft calicut) from the result (00d79e8e609cfbdf5b75d80fdef96fb4).

[Note: Actually there are some hacking strategies to break/interpret md5, but that is out of scope of this tutorial, Ofcourse you can send me a request to know that techniques!!].

User Registration and Login Steps

Now we can check the user registration steps

1. User fills their information in the registration form

2. It is better to use password fields type as password (<input type="password" >)

3. Submitted data is received by the web-server

4. Convert submitted password to md5 code. Discard original password, it will not use anywhere!

5. Save this md5 data in the corresponding field in the database

Now we can check the steps for user login process

1. The registered user now type username and password in the login window.

2. The submitted password is converted to md5 code using md5 function.

3. The code will compare the usernames as well as md5 code based passwords.

5. If they match, it will grant access to the user.

Thus if any hacker stolen the database they will only get Md5 version of the password only. Not their original secret password!!. Thus the users are protected from password hijackers.

But there are also some chances for hacking the password encrypted using hashing algorithm. For showing a demo I am using another hashing function crc32() [md5 code width is 128 character, so for simulation it will take some time, the crc32() use only 32bits for decryption thus its simulation will complete faster]

<?php
$info = "PravySoft Calicut";// CONSIDER THIS IS MY LOGIN PASSORD
echo "My information before crc32=".$info;
$info_hash = crc32($info);
echo "<br>My information after crc32=".$info_hash;
?> 

The screenshot below shows the result of the above code.

From the screenshot it is clear that, the hash code of the string "PravySoft Calicut" is -332908207. Ofcourse a hacker who has stolen the database cannot recover the string ( "PravySoft Calicut" ) from this number (-332908207). But he can login to the website using another password and that hack is explained below. As you know that cr32 using 32 bit encoding, thus it has only 2 to the power 32 (2^32) combinations only. Thus there is a chance for another string to produce the same hash code i.e -332908207. So if you know any other string which has the same hash code (say a duplicate) can be used to login to the website. Use following code for finding duplicate string

<?php
set_time_limit(0);
$var = 0;
while (true)  //infinite loop
{
 $current_value=crc32(base64_encode($var));
 echo "<br>checking value=".$current_value;
    if ($current_value == -332908207) 
    {
        echo "duplicate string is ".base64_encode($var);
        exit;
    }
     $var++;
}
?>

It will take some time to get the duplicate key/string , after getting the duplicate key you can check the hash code of that duplicate key and hash code of your string are equal. (i.e It is same as that of the hash code of the example string "PravySoft Calicut"). Thus you can access to the website using this duplicate key without knowing original string.

How you can escape from this type of hacking. Better idea is to don't use low-range hashing algorithm like crc32. It is better to use Md5() or sha1() algorithms, They have 128 bit and 160 bit hash codes respectively, Thus finding a duplicate key is very difficult and it will take very long time to get duplicate key.

Some hacking sites are keeping large number of duplicate keys to decode the hash code (Hash code database size is in the range of petabyte, ie 1000 terabyte= 1 peta byte). So hackers can find duplicate keys of some hashcodes very easily [ I am not discussing the websites they store this data(I believes that it is unethical )]. It is also a major problem for web developers to protect their website from unauthorized access. So in the next section we will discuss, how you can block duplicate key access to your websites.

It is the time for a small tea!!, I will explain some-other security issues and ways and means to protect your site from hacking, see you soon in the next post!!

Simple php script for making Excel files

Simple PHP script for making Excel files

This tutorial describes a simple way to generate Microsoft excel file from the php script. As you notice that, there are a lot of complicated external libraries for this purpose (like phpexcel etc.). Here I am describing a simple way to generate excel files without using any external libraries.

Please copy following php code to your web server and run the file. You can see that, a spreadsheet automatically generated there and you can download the same. The contents in the excel file are the same which is given in the code.

<?php

header( "Content-Type: application/vnd.ms-excel" );

header( "Content-disposition: attachment; filename=spreadsheet.xls" );

// print here what you want to see in excel for example:

echo 'First Name' . "\t" . 'Last Name' . "\t" . 'Mobile' . "\n";

echo 'Praveen' . "\t" . 'Thappily' . "\t" . '999999999' . "\n";

I believes that this code is self explanatory. The file name should be given in the second header tag. Here the file name is “spreadsheet.xls”. It can be noted that, for changing excel column, you have to use the tab (\t”) switch and similarly to goto the next row you need to use new line switch (“\n”) in the code as demonstrated above. Figure below shows typical output excel file.

You can use the same file for making excel file from your database (mysql or mssql), just read it using select query and echo the contents. if any doubt please contact us

How to connect two Bluetooth serial modules

2016-04-15T12:37:00.000+05:30

Here we are going to look, how we can connect two Bluetooth serial modules.

Here I am taking the example of Bluetooth module HC 05 because it is a widely using Bluetooth serial module (Bluetooth SPP). Serial port Bluetooth module is 3Mbps Modulation with complete 2.4GHz radio transceiver and baseband.

HC 05 Module and important pins

Some of other features of this module are

· Up to +4dBm RF transmit power
· Low Power 1.8V Operation ,1.8 to 3.6V I/O
· Default Baud rate: 38400, Data bits:8, Stop bit:1, Parity:No parity, Data control: has. Supported baud rate: 9600,19200,38400,57600,115200,230400,460800.
· Given a rising pulse in PIO0, device will be disconnected.
· Status instruction port PIO1: low-disconnected, high-connected
· PIO10 and PIO11 can be connected to red and blue led separately. When master and slave are paired, red and blue led blinks 1time/2s in interval, while disconnected only blue led blinks 2times/s.
Auto-connect to the last device on power as default.
· Permit pairing device to connect as default. Auto-pairing PINCODE:”0000” as default Auto-reconnect in 30 min when disconnected as a result of beyond the range of connection.
· Bluetooth protocal: Bluetooth Specification v2.0+EDR
· Frequency: 2.4GHz ISM band
· Modulation: GFSK(Gaussian Frequency Shift Keying)
· Emission power: ≤4dBm, Class 2
· Sensitivity: ≤-84dBm at 0.1% BER

· Security: Authentication and encryption
· Profiles: Bluetooth serial port
· Power supply: +3.3VDC 50mA
· Working temperature: -20 ~ +75Centigrade
· Dimension: 26.9mm x 13mm x 2.2 mm

You can easily connect your android phone/ PC to this HC 05 module. For that, just power ON your HC module, then switch on your PC/Phone Bluetooth. Now search from your PC or Android phone, it will show the device name. Select pair option and give pair password. The default password might be 1234 or 0000. If everything is OK, then your HC-05’s pair LED (if any) will glow.

But if you want to connect to two embedded system device using HC-05 we want to do following tricks.

How to connect two embedded system project using Bluetooth module

HC-05 comes from the factory as SLAVE mode; that means a master (Android/PC) can easily manage the connection between the HC slave connections. But if you are connecting two HC modules, for example, you want to connect two embedded system projects, you should do some tricks!. Otherwise, it will not works.

The reason is that, Initially Both of the modules are in slave configuration and slave-slave (or master-master) communication is not possible. So we want to change the mode of one Bluetooth module for the communication.

For this you need following tools

1. TTL to RS232 converter

2. Terminal Software (you can download it from www.pravysoft.org website)

Normally HC-05 modules are TTL module means if we directly connected this module to PC serial port the RS232 signals from PC will damage our module. So you should use a TTL to RS232 converter. If you are familiar with MAX232 chip, you can make this using simple circuit (visit http://pravysoft.blogspot.org ) for making this module.

HC 05 With built in RS232 PORT

Now you need to connect the RS232 connector to your PC. Latest PC’s does not have serial port (DB9 pin), if so you need to use RS232 to USB converter module, note that you should install proper drivers to work USB to serial converter. You can see the corresponding ports of USB to serial converter in DEVICE MANAGER as shown in the figure.

Serial to USB convertor (Black) and HC 05 module

Device Manager window to find serial port number

If the port number is greater than COM7, change the port number to a lower one. Otherwise, the terminal software won't detects the PORT

Then take your HC05 module and feed a 3.3V voltage for its KEY pin (Please see the first figure).

Some HC05 RS232 modules are coming with KEY PINs, for that you just place a jumper there.

HC05 with Key Jumber is shorted

Open terminal software select correct serial port

Please note that you should select baud rate of 38400.

To test all connections are ok or not, you just type AT and press enter

You will get continuous OK string, don’t worry please power off your HC05 module and reopen terminal now.

Again connect the module using terminal software and sent AT+ROLE=1

Terminal software window

If everything is ok, then your module become MASTER now. To check it is master or not just power ON the device and search it using a phone.

Alternatively power on another HC module (slave config) and Power on configure HC module, if it is MASTER, it will automatically connect to the slave module (Check PAIR LED status)

TIP: Power on slave module before Master one for fast pairing

Upgrade your Android Experience with these Tricks

We all like animations, it make your device feel good but in long term if you see these animations conserve battery and even make your phone a little slower, if you are running a high end phone then these little difference won’t be noticeable for lower end phones you are going to face a lot of issues. So here I would like to explain some tip and tricks to improve battery capacity by reducing animations

For this first you need to become a developer (i.e enable developer option in your phone) this is a hidden feture of latest android OS. So to enable or to see these features please goto your android phone MENU

Phone Settings > About

On the Build Number, TAP 3 times

This will enable the developer options in your android phone.

Save battery now…..!!

Basically there are 3 types of animation scale options you can disable in android that’s is

1. Window Animation Scale

2. Transition Animation Scale

3. Animator Duration Scale

Open setting>developer options
Just open that and scroll that, until you find three options:

Window Animation Scale, Transition Animation Scale and Animator Duration Scale.

Now just press each of them and Turn them Off.

Now restart your phone and see a boosted up phone.

Want to tag Fake GPS location???

After enabling the developer options you can Mock your GPS Location hence you can Fake it, this could be helpful in numerous situations, that relies on upon the way you utilize it.

Explore to Settings > Developer Options,

Check for Mock Locations highlight and enable it by ticking the check box. Now you can give fake GPS tags for various APPs

Keeping your Android Device Awake while Charging

Whle charging android phone lie in ideal state, no RSS or news fields are working on that time. To keep your android phone awake while charging you need to do following trick

Explore to Settings > Developer Options, check for Stay Awake component and enable it by ticking the check box.

Make Desktop Backup Password

Explore to Settings > Developer Options, tap the desktop backup password option, enter your present password and after that new password.

Empower Higher Graphics in Games

If you are getting low graphics in your android games, follow this trick to enhance its resolution.

Explore to Settings > Developer Options, check for Force 4X MSAA include and empower it by ticking the check box.

Enable CPU Usage Overlay

If your battery drain out in the middle of the day, you can use this trick to keep your battery power some more hours.

Navigate to Settings > Developer Options,

check for Show CPU Usage feature and enable it by ticking the check box

Simply use WHATSAPP in your computer !!!

2015-03-05T16:27:00.000+05:30

Even though there is no official whatsapp software work in personal computer, you can access whatsapp in PC using various techniques. For example, with the help of Blue stack software you can install this software on your PC. But in this case you can access whatsapp only in one device (either on PC or Phone) [Whatsapp team always checking your MAC ID for this purpose]. Switching from one device to another is also a time consuming process (SMS or Voice validation is needed each time). So as a solution for this problem whatsapp team introduced a new technique. Now you can use whatsapp in your computer browser

To get startedplease follow these simple steps

Realize the cheating through Facebook!! Facebook-ലൂടെ ഉള്ള കബളിപ്പിക്കല്‍ തിരിച്ചറിയൂ!!

2013-11-11T16:32:00.002+05:30

Realize the cheating through Facebook!!

(English version below)

Facebook-ലൂടെ ഉള്ള കബളിപ്പിക്കല്‍ തിരിച്ചറിയൂ!!

“അസുഖം ബാധിച്ച ഈ കുഞ്ഞിന്റെ ഫോട്ടോ ലൈക്‌ ചെയ്യു Facebook അവര്‍ക്ക് പണം നല്‍കും”.

നിങ്ങള്‍ ഇങ്ങനെയുള്ള ഒരുപാടു പോസ്റ്റുകള്‍ facebook-ല്‍ കാണാറുണ്ട്‌ അല്ലേ, facebook അവര്‍ക്ക് പണം നല്‍കുമോ??

ഉത്തരം: ഇല്ല.

Facebook- ഒരു പോസ്റ്റ്‌ എല്ലാവരും കാണാന്‍ ആഗ്രഹിക്കുന്നു എങ്കില്‍ നിങ്ങളുടെ LIKE എന്തിന്‌? നിങ്ങളുടെ അനുവാദം പോലും അവര്‍ക്ക് ആവശ്യം ഇല്ല. അത്തരം പോസ്റ്റുകള്‍ നിങ്ങളുടെ timeline-ല്‍ automatic ആയി വന്നോളും.

2. നിങ്ങളുടെ ലൈക്‌ കൊണ്ട് facebook-നു ഒരു പൈസയും ലഭിക്കുന്നില്ല. ആയതിനാല്‍ അവര്‍ക്ക് നിങ്ങളുടെ ലൈക്‌ കൊണ്ട് ഒരു ആവശ്യവും ഇല്ല.

3. Facebook അങ്ങനെ പണം രോഗികള്‍ക്ക് നല്‍കുന്നെങ്ങില്‍ അത് ഒരു ബ്രീകിംഗ് ന്യൂസ്‌ തന്നെ ആകും കാരണം 1 billion ആളുകള്‍ ദിവസവും facebook-ല്‍ ഇത്തരം POST-കല്‍ ലൈക്‌ ചെയ്യുന്നു. ഓരോ ലൈക്‌-നും പണം കൊടുത്താല്‍ അത് എത്ര വലിയ തുക ആകും . ഞാന്‍ ഇത് വരെ അത്തരം ഒരു വാര്‍ത്ത‍ കണ്ടിട്ടില്ല.

ആളുകളുടെ വികാരങ്ങള്‍ മുതലെടുത്തു അവരെ ചൂഷണം ചെയ്യാന്‍ ആഗ്രഹിക്കുന്നവര്‍ ആണ് ഇത്തരം പോസ്റ്റുകള്‍ FACEBOOK-ല്‍ ഇടുന്നത്. ആയതിനാല്‍ ഇന്ന് മുതല്‍ ഇത്തരം പോസ്റ്റുകള്‍ കണ്ടാല്‍ ഷെയര്‍ ചെയ്യരുത് LIKE ചെയ്യരുത്.!!

Does Facebook Pay Money To The Victims For Likes On Posts?

NO, NOT at all.

1 If Facebook wants to publish a particular post to see everyone, they don’t want you like or your permission. It will come on your timeline automatically.

Facebook DOES NOT receive any payment when you like or comment anything. This is just a feature of the Facebook API to store like, comments and shares.
If Facebook actually pays that amount to the victim , It should be breaking news and you can see that in newspapers or TV.

Thus these types of posts are foolishing people by touching their emotions. They are promoting their stuff in a very bad manner. So please don’t like or share this type of posts on Facebook.

Trick for sending “Anonymous call” for free

2013-10-14T12:59:00.001+05:30

Trick for sending “Anonymous phone call” for free

Dear friends,
Here I am presenting a simple trick to send anonymous miscall to your friends at any time.

Consider the following situation,
You want to disturb your friend at night (say 1 am) by calling into his/her mobile/Land line. For that following restrictions are there
1.    If he/she is taken your call at that time you will loss your call charge.
2.    You want to hear some abuse from that person (Monkey, Donkey, Idiot, stupid etc. As per your     standard variation may exist!!)
3.    You have to awake at 1 am for miscalling your friend. Means your sleep also in trouble.

Now I am presenting to solve these restrictions.

Please note that your computer date and time should be correct.

1.First you have to visit the website https://wakeup.io. No registration/Login required.

2.Set your friend’s (The victim’s!!) mobile number as shown in the figure (For testing put your number instead!)

3. Set Date and Time (Dont use time 12:xx Use 6:00pm 7:00pm etc ) in the form and click “Schedule free wakeup call button”

Wait for that time, You will get an Anonymous phone call from Washington DC!!!

Note: Please don't use this trick for disturbing a person. PravySoft is not responsible for any damage caused by this trick. This trick will not work always because we are using free plan (Not the pro) so you can set only 2 calls/day. If you want more calls means pro account, Please inform me , I have trick for that also info.pravysoft@gmail.com

Double or multiple touch sensing APP INVENTOR Canvas

2013-09-28T16:17:00.001+05:30

In this tutorial I am explaining about how to sense double touch (Multiple click) in MIT APP Inventor Canvas.

App Inventor is a very good and simple tool for Android development invented by google labs and now hosted in MIT server. A CANVAS is a two dimensional touch sensitive rectangular panel on which drawing can be done and sprites can be moved . With the help of CANVAS, you can make variety of applications and that palatte is capable to track your gestures on the touch screen. Unfortunately, APP inventor team (Google, MIT) not given any answer for the question, “How to sense the double or multiple touch using CANVAS ”. I have searched on many websites, But I didn’t get any response. Thus I created a block to sense app inventor double/ multiple touch action (Double Click). With the help of this tutorial you will study how you can use the timer or clock pallatte for your android development.

LOGIC Behind this work

Sensing: How often you touched up the canvas for a short interval (~500 milli seconds=1/2 seconds).

At First you have to insert following Pallates using APP inventor designer webpage

CANVAS
CLOCK
TEXT BOX

Click save and open CODE EDITOR (on a JAVA installed system)

STEPS

For that you need a global variable , that will store your number of clicks (Touch)

to make a global variable

Click on Definition> Name block

Give a suitable name . In my case I have given name “time”.

Next You have to give a time interval for timer, for double click we need only ½ seconds only. So I have given timer value to 500 mS. I have put that block in screen initialization block (See the figure).

Canvas1.Mouse touch up will give information about how often you touched the canvas.

If you clicked multiple times , variable "timer" will increase by 1 (see math block inside Canvas1.Mousetouchup block). At the end of 1 timer cycle (500 mS). An interrupt will be fired and the entire execution cycle of the program will reach in the clock1.timer block, In that block I printed the number of clicks stored in our global variable (timer) to the TextBox1. After printing the value on text box 1, set the time variable value to zero.(Otherwise it increases with every click)

Mozilla firefox latest version module:Do not track

2012-03-08T09:15:00.000+05:30

Mozilla Delivers New Version of Firefox – First Web Browser in the world to Support Do Not Track on Multiple Platforms

Mozilla, a global, nonprofit organization dedicated to making the Web better,On december 2011 released a new version of Mozilla Firefox for Windows, Mac, Linux and Android. The new version of Firefox comes on the heels of the wildly successful release of Firefox 4, which had more than 200 million downloads on Windows, Mac and Linux and millions of downloads in the Android Market.

Mozilla’s shift to a rapid release development cycle delivers cutting edge Firefox features, performance enhancements, security updates and stability improvements to users faster.

The latest version of Firefox includes more than 1,000 improvements and performance enhancements that make it easier to discover and use all of the innovative features in Firefox. This release adds support for more modern Web technologies that make it easier for developers to build amazing Firefox Add-ons, Web applications and websites.

Firefox for Android includes the Do Not Track privacy feature in this release, making Firefox the first browser to support Do Not Track on multiple platforms. Mozilla created Do Not Track to give users more control over the way their browsing behavior is tracked and used on the Web. The feature, which lets users tell websites that they wish to opt-out of online behavioral tracking, is now easier to find in Firefox Preferences.

Firefox offers users complete control over the look and functionality of their Web browser with a gallery of hundreds of thousands of add-ons. About 85% of Firefox 4 users have an add-on installed to customize the look, features and functionality of their Firefox.
Mozilla has a rich set of resources that make it easier for Web developers to build compelling Firefox Add-ons using HTML, JavaScript and CSS. The new Firefox Add-on SDK for Windows, Mac and Linux enables local development of add-ons, while the Firefox Add-on Builder Beta provides a hosted Web-based build environment. Developers can build Firefox Add-ons for all platforms that install and update without requiring a browser restart or interrupting the Web browsing experience.
Firefox for Windows, Mac and Linux now supports the CSS Animations standard to enable developers to build more amazing Web applications and websites. Mozilla Hacks has a tutorial on CSS Animations and a comprehensive blog post explaining what developers can create with Firefox.
To get the latest version of Firefox for Windows, Mac or Linux click on “check for update” under the “About Firefox” menu or download the Firefox Aurora and Beta channels here. Visit this page to get the latest version of Firefox on your Android device or to join the beta. Users with Firefox for Android installed will receive a notification to update to the latest version.

2011-03-07T15:03:00.000+05:30

PHP web spider

Tutorial below shows how to make custom search engine by using yahoo boss api. If you're looking for search engine customization, then building your own search engine is something you'll want to look into. Here we are using an api provided by yahoo search service. Search APIs are nothing new, but typically they've included rate limits, strict terms of service regarding the re-ordering and presentation of results, and provided little or no opportunity for monetization.

These constraints have limited the innovation and commercial viability of new search solutions. The name of the api is BOSS.

BOSS (Build your Own Search Service) is different; it's a truly open API with as few rules and limitations as possible. With BOSS, developers and start-ups now have the technology and infrastructure to build next generation search solutions that can compete head-to-head with the principals in the search industry.

Now we can go through the code

At first you need to create an HTML web search page as shown below

pravysoft

you will get a text box ,shown below

pravysoft<span style=""> </span>web search

Here I am created a text box with name “search” and a submit button. Here I am used POST method for sending form variables. For simple usage action=””, which means post the information on the same page.

Now we can look on the main code for web search engine.

if(isset($_POST['submit']))
{
$search=$_POST['search'];
$request="http://boss.yahooapis.com/ysearch/web/v1/".$search."?format=xml&appid=Uz.......................";
//replace appid with your id
$ch = curl_init($request);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$xml = simplexml_load_string (curl_exec($ch));
// Display search results - Title, Date and URL.
foreach ($xml->resultset_web->result as $result) {
print ''.$result->title.'
';
}
}
?>

At first you can see isset($_POST['submit']) code .which checks whether user clicked on the submit button or not. if this function returns 1.that means user clicked on the button.Then read the contents of the text box with the help of POST function.on the next step you have to replace “ appid” with your own BOSS id

You will get api id from yahoo boss web site BOSS web site

after replace the pravysoft appid with your own boss id .you can easily make your own web spider.

Now we can go through the PHP cURl function.cURL is a library which allows you to connect and communicate to many different types of servers with many different types of protocols. Using cURL you can:

PHP cURL library is definitely the odd man out. Unlike other PHP libraries where a whole plethora of functions is made available, PHP cURL wraps up major parts of its functionality in just four functions.

A typical PHP cURL usage follows the following sequence of steps.

curl_init – Initializes the session and returns a cURL handle which can be passed to other cURL functions.

curl_opt – This is the main work horse of cURL library. This function is called multiple times and specifies what we want the cURL library to do.

curl_exec – Executes a cURL session.

curl_close – Closes the current cURL session.

Please note that our BOSS api returns output as simple xml format.which contains information like click url,title etc.So we have to convert the xml data and to access the click url its better to insert xml parsed datum into an array.

Here I used an array $result to store xml parsed data. Then with the help of foreach loop, I separated each title and click url by giving necessary indexes to the result array and placed necessary places of the HTML page.

Complete code below

if(isset($_POST['submit']))
{
$search=$_POST['search'];
$request="http://boss.yahooapis.com/ysearch/web/v1/".$search."?format=xml&appid=Uz.I................";
$ch = curl_init($request);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$xml = simplexml_load_string (curl_exec($ch));
// Display search results - Title, Date and URL.
foreach ($xml->resultset_web->result as $result) {
print ''.$result->title.'
';
}
}
?>

Firefox Password Silent Saver

FireFox Password HACKER

PLEASE USE THIS TOOL FOR EDUCATION PURPOSE ONLY

Hi Here I am introducing a software, which will store all username and password of the user who uses Mozilla Firefox browser (Without showing popup button like below). With the help of this software we can hack user name and password of users.

In Firefox, even if you have the option “Security Remember passwords for sites” checked in Tools > Options, the browser will still display a notification bar at the top that asks “Do you want Firefox to remember the password for “Username” on website.com?” with three buttons “Remember”, “Never for This Site” and “Not Now”. If user pressed on "Remember" button password will store on firefox database and we can see the password. If user preseed other button we will not get his/her password.

My idea is to block this message box(see above) and click on Remember Button. The first thing that came to my mind was perhaps there is an addon that can do this but I couldn’t find any addon that can make Firefox auto save password without prompting. After spending nearly 2 hours researching on how Firefox saves the password, I managed to find a way on how to make Firefox save the login information to the Firefox Saved. So I am created this software.Please dont use this tool for hacking confidential data(s). Please use this tool for education purpose only
