PHP - Code Will Not Work After Adding Sha1 And Salt Encryption

Hello,
I have one line that I can't understand of PHP code used to encrypt strings:
$temp = ord(substr($str,$i,1)) ^ 203;
I understand everything but this " ^203 "
Can you explain me what it does?

I need a simple two-way encryption algorithm that does not require mcrypt.  What did PHP use for 2ways prior to mcrypt?  The reason for this is installing mcrypt on our production server requires a recompile of PHP and I'm not keen on doing that on a production server.  Security and bit-length of the algo is not that important.  Please advise.

This one requires lots of up front information:

I have a page, for this example that I will call page.php. It takes get parameters, and for this example I'll call the parameter "step". So I have a URL like this: page.php?step=1 This page has a form with an action of page.php?step=1. The code on the page validates the posting information. If the information is bad, it returns the user to page.php?step=1; if it is good, it takes the user to page.php?step=2 via header( "location:page.php?step=2" ). So redirection is done by relative path, not full URLs.
This all works as expected.

Now what I've done is set .htaccess to be HTTPS for this page, via this code:

# Turn SSL on for payments
RewriteCond %{HTTPS} off
RewriteCond %{SCRIPT_FILENAME} \/page\.php [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

This works (initially). However, once you try to post the form, it just redirects back to the step=1 version of the page. I really don't know how or why that would be.

I'm not sure how else I can explain this or what other information you may have. But it's frustrating to not get a page working in HTTPS that works in HTTP. Very odd. Any suggestions? (I don't even really know the best location to figure out when/why it's redirecting back to the original page.)

Hi, I have some code which displays my blog post in a foreach loop, and I want to add some social sharing code(FB like button, share on Twitter etc.), but the problem is the way I have my code now, creates 3 instances of the sharing buttons, but if you like one post, all three are liked and any thing you do affects all of the blog post. How can I fix this?


<?php
include ("includes/includes.php");

$blogPosts = GetBlogPosts();

foreach ($blogPosts as $post)
{
echo "<div class='post'>";
echo "<h2>" . $post->title . "</h2>";
echo "<p class='postnote'>" . $post->post . "</p";
echo "<span class='footer'>Posted By: " . $post->author . "</span>";
echo "<span class='footer'>Posted On: " . $post->datePosted . "</span>";

echo '

echo "</div>";
}


?>

Is there anything wrong in doing this?

I currently have 100,000+ users all with their passwords hashed in md5(). I want to secure it a bit by simply hashing all of their existing hashes to sha1() and then check their password matches the sha1(md5()).

Is there any reason why I shouldn't do this?

Is this okay to do for dealing with passwords before running an insert query into a database?

$password = sha1(mysqli_real_escape_string($dbc, $_POST['password']));

Hi,
So basically this is error:
Code: [Select]
  if (strcmp($extuser,$username) == 0 && strcmp($extpass,$password) == 0)

extpass is a value it reads from the database. That value is sha1-hashed.
Password is plain and is sent via a form.

So what happens is the following:
extuser and username equals 0, as they match. extpass and password matches IF i put the sha1 hashed password as the password.
So no problems in that, it's supposed to work that way.

If we change the code a bit, so that the user shouldn't post an unknown password:
Code: [Select]
  if (strcmp($extuser,$username) == 0 && strcmp($extpass,sha1($password)) == 0)

Right, so we take the submitted password and sha1 it. Then check if that new string matches the database and whops, login failed.


Okay.. by doing some debugging by printing the actual values i conclude this:
The sha1($password) equals 139a8cf8be8..... while in my database all the letters are CaSe. This is most likely the error.. Any ideas for a fix?

I have the following array which builds a concatenation of the items in tree-like form.



$arrayT = array();
$arrayT[0] = "a";
$arrayT[1] = "b";
$arrayT[2] = "c";
$arrayT[3] = "d";
$arrayT[4] = "e";
$arrayT[5] = "f";
$arrayT[6] = "g";
$arrayT[7] = "h";

$arrayT = buildTree($arrayT);

print_r($arrayT);

function buildTree($array) {
    $arrayTree = $array;
    $start = 0;
    $end = count($arrayTree);

$i = 0;
    while ($start != $end - 1) {
        if ($i % 2 == 1) {
            $arrayTree[count($arrayTree) - 1].=$arrayTree[$start + $i];
        }
        else
            $arrayTree[] .= $arrayTree[$start + $i];
        $i++;
        if (($start + $i) == $end) {
            $i = 0;
            $start = $end;
            $end = count($arrayTree);
        }
    }
    return $arrayTree;
}



Example output is

Quote

Array ( => a [1] => b [2] => c [3] => d [4] => e [5] => f [6] => g [7] => h [8] => ab [9] => cd [10] => ef [11] => gh [12] => abcd [13] => efgh [14] => abcdefgh )


I would like the values to be hashed using sha1. e.g value at [8] ab would be the hash of a and [1] b, value [12]abcd would be the hash of the values at [8]ab and [9]cd. I modified it myself in the next code snippet but I still don't feel it's doing what it's meant
function buildTree($array) {
    $arrayTree = $array;
    $start = 0;
    $end = count($arrayTree);

$i = 0;
    while ($start != $end - 1) {
        if ($i % 2 == 1) {
            $arrayTree[count($arrayTree) - 1].=$arrayTree[$start + $i];

sha1($arrayTree[count($arrayTree)-1].=$arrayTree[$start + $i]);
        }
        else
            $arrayTree[] .= sha1($arrayTree[$start + $i]);
        $i++;
        if (($start + $i) == $end) {
            $i = 0;
            $start = $end;
            $end = count($arrayTree);
        }
    }
    return $arrayTree;
}

$val1 = sha1($arrayT[0]);

$val2 = sha1($arrayT[1]);

$val3 = sha1($val1.$val2);

$val4 = sha1("ab");
echo "VAL1 ".$val1;
echo "<br/>";
echo "VAL2 ".$val2;
echo "<br/>";
echo "VAL3 ".$val3;
echo "<br/>";
echo "VAL4 ".$val4;



Anyone any ideas? Thankyou.

Hello all,

I looked everytwhere to find the answer to my question bug so far, no luck. I hope someone here can help me with this issue.

Oke, my problem is as following.

I'm creating a string with a foreach loop that I then will has after the loop. The problem is, is that that string is addad to a variable. When I sha1 hash that variable with the sha1 function from within PHP I get a different hash as when I just echo the string and manually hash that.

The point is, is that the manually hashed string is then correct, and the automitically hash string isn't.

This is the code I'm using, can someone tell me where to look at to solve this problem?


if (is_array($this->getFormData())){
     foreach ($this->getFormData() as $name => $value) { 
         $string .= $name."=".$value.$shamethod;
   }
}
$hashstring = sha1($string, false);
echo '<br /><br />'.$hashstring.'<br /><br />';
echo $string;


Thanks for  your time.

Dok

Php Lovers,

 

When you register on my site, you supposed to get an account activation link emailed to confirm your email and account opening.

Activation Link contains activation code. Code, I wanted all numbers like so: 193736262829292

And not alphanumerical like so: djkqh3kl3lwnj3j22b

Someone did this line for me 1.5yrs back and only just came to my attention it is generating alphanumeric chars as I was checking the column where it would save the code to see if the column type is correct or not. Type was varchar all this time. If the code becomes only numerical then can switch column (account_activation_code) type to "INT".

	$account_activation_code = sha1( (string) mt_rand(0,99999999)); //Type Casted the INT to STRING on the 11st parameter of sha1 as it needs to be a string.         
	

Another programmer did that line 1.5yrs back. Lost contact with him. Tell me, why sha1 needs to be TypeCasted to "STRING" ? As far as I remember 1.5yrs back it had to be converted to STRING. Else, was giving error. I mean, we dealing with INT here "mt_rand(0,99999999)" so why php force us to TypeCast to STRING here ? Absurd! Right ?

I am still experimenting with SANITIZATION and so ignore the SANITIZATION lines.

 

Hi guys I have a script which i've been playing around with thanks to Spiderwell: http://www.phpfreaks.com/forums/index.php?action=profile;u=35078

I have sort of merged it with another 'member managment' script which is working great.

Now i can't seem to correctly create a login page to pass the hashed password using (sha1).

Now all i want to do is verify the username and the (hashed) password according to the database and allow the user in. The script i am using to check login works fine without a hashed password in the database. But ideally i'd like to use a hashed form of password.

Can somebody show me what change i need to make in this script below in order to pass a sha1 hashed password? I'm guessing it's a really small change from the examples i've seen online, but i just cant seem to get mine to work. :|

Your help would be much appreciated.

Login Page PHP:

Code: [Select]
<form name="login" method="post" action="check_login.php3">
<p><strong>Secured Area User Log-in</strong></p>
<p>Username: <input name="bioname" type="text" id="bioname"></p>
<p>Password: <input name="biopass" type="password" id="biopass"></p>
<p> </p>
<p><input type="submit" name="Submit" value="Login"></p>
</form>

Check Login Processor (which is the file i that needs the sha1 added somewhere i think)

Code: [Select]
<?php
require_once('config.php3');

// Connect to the server and select the database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db")or die("Unable to select database");


//
$loginusername = false;
$loginpassword = false;


$err = false; // default error message is empty

// The username and password sent from login.php
//the isset() basically means if its there get it, otherwise dont bother

if (isset($_POST['bioname'])) $loginusername=$_POST['bioname'];
if (isset($_POST['biopass']))$loginpassword=$_POST['biopass'];

// if either isnt filled in, tell the user, a very basic bit of validation

if (!$loginusername || !$loginpassword) $err = "please complete the form";
if (!$err) //if no error continue

{
//The following bit of coding protects from MySQL injection attacks

$loginusername = stripslashes($loginusername);
$loginpassword = stripslashes($loginpassword);
$loginusername = mysql_real_escape_string($loginusername);
$loginpassword = mysql_real_escape_string($loginpassword);

//you could add other things like check for text only blah blah

$sql="SELECT * FROM $tbl WHERE bioname='$loginusername' and biopass='$loginpassword'";

$result=mysql_query($sql);
// Count how many results were pulled from the table
$count=mysql_num_rows($result);

// If the result equals 1, continue
if($count==1)
{
session_start();
$_SESSION['user'] = $loginusername; // store session data
//please see I have used a session variable that is generic not specific, otherwise you will have to make this page different for every user
//that would be a pain in the ass, you don't need to have user1 or user2, its the value stored that relevant, not what the variable name is
header("Location: {$loginusername}/index.php3");

}
else 
{
$err = "Wrong Username or Password";
}
}// end login if statement

if ($err) // show error message if there is one
{
echo $err;
echo "<br>Please go back in your browser and try again";
}
?>


The secure page:

Code: [Select]
<?php
session_start(); 

$mypath = $_SERVER["REQUEST_URI"];
//echo $mypath; // for debugging
//now we have the path lets see if the username is in that path, i.e. test2 is inside /something/test2/index.php 
//use the built in strpos() function, which returns position of the last occurance of the string you are looking for inside another string.
//http://php.net/manual/en/function.strrpos.php

if(strpos($mypath,"/".$_SESSION['user']."/"))//on testing it failed initially as username test is found in path /test2/ so i added the slashes to stop that. so /test/ doesnt get found in /test2/
{
echo "congratulations you are the right person in the right place";
}
else
{
 session_destroy(); //kill the session, naughty person trying to come here
 header("Location: ../login.php3");
 die();// stop page executing any further
}

?>

Thanks and i look forward to your replies.

Hi everyone 

I'm new around here but thought it's about time I joined a good PHP forum! I'll introduce myself properly on the right section, but for now, I'll my post my coding problem on here. I wonder if any has any knowledge or can help.

I'm setting up a connection from my web server to a potential data supplier web server, which involves a load of encryption. One of the stages is generating a SHA1 hash of an encrypted string.

Now I've got some old example code, however the "mhash" function used in this old code appears to obsolete. Thus is doesn't work.

I've tried using the available "sha1" and "hash" functions but cannot replicate the hashed output they provide.

Here's the original code:
Code: [Select]
$encrypted_string = "B0436CBFBC5CAAFB7339AF4A1DF845974D53B9D369146E2E4F1451929D9EBE254363E983F4F94517EB9585FDB112E7B1CCE11A33C5BBA23F8D5DE9D3415BA526489AC796A36FBA76D4293C8DFB673708CED10C9732EEC472D9E43D2626AA104121666E79DD8F2FF6BAC0143BD62E0EE826AF6459779C162613508D48BFE2FC8DD558A1834D7205F96EA8D446E9B371E78E990A3995B1052DCBA9CA0AF99CC77ED2A8B55B2B882BA29D4BB4B07FA91AB4D2F10FBB93732B077335A7E6D96FE813AEDC3711A85CD0C13AE22B28C14FCCE3AF4C1F5D2C0F7697DEC7487CCFC0ED4E77B1B65F39BAD5236E3D3C69D33FC484";

$hashBinaryValue = mhash(MHASH_SHA1, $encrypted_string);
$hashValue = bin2hex($hashBinaryValue);
echo 'hashValue='.$hashValue.'<br>';
The example hashed output should be:
Code: [Select]
31f6d26b18d3c04895cdc2cc05cbd9ad003f2d3e
I cannot seem to replicate this output using the available functions? I've tried the following:
Code: [Select]
$hashBinaryValue = hash('sha1', $encrypted_string);
$hashValue = bin2hex($hashBinaryValue);
And also:
Code: [Select]
$hashBinaryValue = sha1($encrypted_string);
$hashValue = bin2hex($hashBinaryValue);
Both generate:
Code: [Select]
37333736363862393037313732326265346438396433633236383936363430376434613665363231
I've found a webpage that can generate the SHA1 hash, but do not know what language they've done it in.
http://www.fileformat.info/tool/hash.htm?hex=B0436CBFBC5CAAFB7339AF4A1DF845974D53B9D369146E2E4F1451929D9EBE254363E983F4F94517EB9585FDB112E7B1CCE11A33C5BBA23F8D5DE9D3415BA526489AC796A36FBA76D4293C8DFB673708CED10C9732EEC472D9E43D2626AA104121666E79DD8F2FF6BAC0143BD62E0EE826AF6459779C162613508D48BFE2FC8DD558A1834D7205F96EA8D446E9B371E78E990A3995B1052DCBA9CA0AF99CC77ED2A8B55B2B882BA29D4BB4B07FA91AB4D2F10FBB93732B077335A7E6D96FE813AEDC3711A85CD0C13AE22B28C14FCCE3AF4C1F5D2C0F7697DEC7487CCFC0ED4E77B1B65F39BAD5236E3D3C69D33FC484

Any help or input would be greatly appreciated =)

I honestly don't think salt is necessary with my system. I currently use:


$password = md5(sha1(md5(sha1($_POST['password']))));


Is this good enough when it comes to storing a password, encrypted?

which would be secured to use friends? or could we use both together?

show some usage example please
