PHP - Help With Encrypt/decrypt Using A Combination Of Md5 And Initilization Vector.

what is a code to decrypt md5 password for viewing by member?

Hi,

My understanding of 'SHA' command is to encrypt the password, however is there a way to decrypt the password after the encryption? Thanks

$query = "INSERT INTO mismatch_user (username, password, join_date) VALUES ('$username', SHA('$password1'), NOW())";

    $space = array('3x3', '3x3_6x6', '3x3_6x6', '6x6_10x10', '10x10_20x20', '20x20_40x40', 'above_40x40');

Hey all I've found some combination functions out there but they're not working really like I want.

I have an array with some currencies:

array('SEK', 'EUR', 'USD', 'GBP', 'DKK', 'NOK', 'ISK');

Now I want the function to generate an array with all possible pairs:

array(array('SEK', 'EUR'), array('SEK', 'USD') ...)

It must allow for the inverse form: EUR, SEK is different from SEK, EUR.

But trash all pairs that are equal: SEK, SEK or EUR, EUR.

Help me out?

Honestly, for something like this I don't know how to go about creating this script..

So I want to create a script that will generate every combination of 2 numbers that range from 0-749, so 750x750 = 562500 possible combinations, so for example, 0/749, 43/87, 0/0, 1/1, 2/1, 1/2, 500/450, 405/673, etc..

How would I go about starting to write a script that can generate all of the possible combinations and and put them in an array or write them to a file?

Thanks for the help in advanced!

Hi

I allow users to log in, they are redirected to a page and in the url their account ID is carried e.g. accountid=2.  Obviously they could alter the number and potentially see other members details.  What is the best way to hide this information?


Thanks

Hi...

I have a problemand I tried to resolved it but still I failed..

I need to add a code in a php file where I'm not the one who code, now I need to add code on that file, and the problem is the one who the owner of code is not here.

I need to add code :

Code: [Select]
$sub_lotcode = substr($lotCode, 9, 4);
   
    $sql = "SELECT k.PCODE, k.kanban, p.Compounds, p.Max_Lot
            FROM kanban_checker k, param_settings p
        WHERE k.kanban = p.Max_Lot AND k.PCODE = '$sub_lotcode' AND p.Compounds = '$sub_lotcode'";
        $result = mysql_query($sql, $con);
         $total = mysql_num_rows($result);
        if ($total <= 0) {
            notify that PCODE reach the maximum        }
        else{
            echo "continue";
        }

here is the code where I need to add this condition:

Code: [Select]
<?php
error_reporting(0);
$con = mysql_connect('localhost', 'root','');

if (!$con) {
    echo 'failed';
    die();
}

mysql_select_db("mes", $con);

$lotCode = mysql_real_escape_string($_GET['normal']);
$lotCodeDownGrade = mysql_real_escape_string($_GET['downgrade']);
$terminalNo = mysql_real_escape_string($_GET['n']);

Is there an alternative way to encode url params besides:
base64_encode()

examples would be great.

Hi, for my php program running in command line (windows cmd), the user must login first, so my ques is how can they enter the password as *****

Hi, I want to send a URL to a user with their name in it: index.php?user=tom

how can I encrypt this name so that I can track what they do but if I was hacked nobody else could determine who the user was?

Thanks

Hi all
I wonder if somebody could give me some guidance on this.

I manage a website programmed in PHP and having MySQL backend. Recently some of my clients raised concerns about the security of their data. It is not credit card information or so, however I would like to sort it out.

I have a button on the web site which the clients click to tell me that their data should now be analysed and a report sent to them. My php program pulls out the records for this particular user and writes them into an excel file on my web space(on a shared hosting). The same php program then attaches this excel file to an email and sent it to me.

I want to make sure that this data in the excel file is securely transmitted during the above process.

Any help would be much appreciated.

This is my code it's not working.

$username = $_POST['username'];


        $password = $_POST['password'];
        $encrypt_password = md5($password);

        $email = $_POST['email'];


        $usrsql = "SELECT * FROM $tbl_name WHERE username='$username' AND password='$encrypt_password'";

//--> Below is the INSERT Code

$query = "INSERT INTO `x_users` (username, password, email) VALUES ('$username', '$encrypt_password', '$email')";

        $result = mysql_query($query);

        if($result == 1) {

            print("Thank you, your accout has been created!");
        }

Can anyone tell me why the md5() function is not working?

Hey guys!
I have a doubt and this is a question that relates Flash and PHP...

I have a flash (swf) file that grabs/sends variables from/to php.
That swf file is FULLY encrypted and the paths to the PHP urls are also encrypted.

Is there any other way a hacker could find out where and which my PHP files are located/named?

Any ideas, suggestions?
Thanks in advance!
Cheers,

Can php encrypt a link so that it's hidden or expires after a download or x number of days? An example of this use would be on music download sites.
