does anyone have a tutorial for making protection a software verification using php, vbscript or java script?.

e.g:

matching serial online.

The same thing is there in this forum? maybe should I know?

You mean sending HTTP requests from your app to your server, to a script to verify said codes?

For starters then, in your programming language look at sending requests to pages and parsing responses.

something like that, Application will send SerialNumber to the engine java script / php and corrects a valid or invalid serial is submitted into the script, if the serial is valid then will send back a message to the application (serial is submitted that the application is appropriate /valid and make permanent configuration), otherwise it will block the application

Need to know what language you are using.

I hope if there is source code written using Delphi and PHP

http://stackoverflow...ing-wininet-api

Synapse seems to be most likely what you need in Delphi.

For C/C++, things like CURL and crap exist. And for .NET, its features are quite adequate for XML parsing and HTTP requests.

thx u, I'm going to get there

probably are too simple, I tried looking on google but did not know the term

think about what keywords are associated with this??

I can help you write some simple php... planning to use a plain php + mysql ?

yupz, not too complicated but it can run properly, and that is certainly easy to learn

or would that what you think?

NB: sorry if too often I edit, probably exactly like checking the serial number is a software that made ​​a large software company.

Edited September 2, 201212 yr by X-88

quite easy to learn indeed, but you should do some trick with that serial (for example returning a decryption constant that decrypts the serial to a name in order to verify)

pm me if you need help with the php, although there are many good examples on the net

greetz

Client side: using libcurl to POST or GET its md5 to server and retrieve header from server, you can download library from here:

http://curl.haxx.se/download.html

Server side: using php to verify the md5 and use header function to send header with verified info to client app.

This is what i'm using in one of my apps :

<?PHP
$licid = $_GET['licid']; // you can also use a  $_POST instead$db = mysql_connect('localhost','<mysqluser>','<mysqlpass>');
mysql_select_db('<mydsl licdatabase>',$db);
$query = "select * from licenses where licid = '" . $licid . "'";$result = mysql_query($query,$db);
if (mysql_num_rows($result) == 0) {
  mysql_free_result($result);				 
  echo "LICUNKNOWN";
} else {
		 echo "LICOK";
	    }
?>

the php script will return "LICUNKOWN" or "LICOK" as response depending if the lic is ok or not..

also.. try to encrypt verification url in your code aswell... so it will a least be more difficult to find the validation stuff...

instead of :

url = 'http://myserver.com/validate.php?md5='

make something like (DES triple)

url = '83f82345f173298f6614f2af67103d2c948188e2cf059e04615841a3cc52cbfb67df554fed5ae9bd'

and decrypt it back to plaintext url just before you need it...

Just a suggestion

Edited September 4, 201212 yr by DE!

@DE!: Your script looks good, but anyone with a little php skill and knowledge of the hosts file will be able to circumvent your protection easily

This script will mark all serials as ok (on server base):

<?php
echo 'LICOK';
?>

Better idea is to store actually needed data in the serial, for which a decryption key/part of a key will be sent by the server....

Greetings

Another gud idea is to check the user agent, in this way you can disable the whole script for regular browser users

Edit: another snippet for the user agent

if($_SERVER['HTTP_USER_AGENT']!="PasteSync") //Normal browser
{
    $real_error=mysql_error();
    $error_msg = "<font color='red'><b>MySQL Error:</b> $real_error</font>";
    echo "<title>PasteSync</title><link rel=\"shortcut icon\" href=\"./pastesync.ico\"/>";
    echo $error_msg;
}
else //My android app I created this for
{
    echo "Server error...";
}

Might I say that you guys should pay more attention to security.. SQL injections everywhere..

Interesting... is there maybe a quick way to protect ourselves? Im not really familiar with stuff like that actually

Edit: mysql_real_escape_string() seems to do the job mostly...

Edited September 5, 201212 yr by Mr. eXoDia

Might I say that you guys should pay more attention to security.. SQL injections everywhere..

The script was just a quick example... You should indeed escape the 'licid' to avoid sql injection.. your 'licid' can also be RC5 encrypted and could be some concatenation of a hwid and a registrationame or simular ... so it would be more difficult to guess values...

@Mr. eXoDia

True, a simple script that returns 'LICOK' would also pass the validation.. But as said.. this was only a sample script... you could play with encryption based on session id's, use different kinds of validation at diffirent times .. do a validation after 5 mins, not only on startup and so on....

DE

ok, suppose I agree with your opinion, but if the user name and the password is different, will it works properly?.

hmm..., sorry, I'm not using my computer so I have not had time to try it.

Edited September 9, 201212 yr by X-88

ok everyone, thank you for taking the time.

This is what I mean, but checking the password in php not so perfect as I expected
