PHP - Updating Hash Password
Hi,
I am trying to get this script to execute as an administrator of an online system. If a user has forgotten their password, I enter their username and enter a new password which they can update later. I am not sure why this is not updating the password for the username entered?
<?php
// Initialize the session
session_start();
// Check if the user is logged in, if not then redirect to login page
if(!isset($_SESSION["loggedin"]) || $_SESSION["loggedin"] !== true){
header("location: login.php");
exit;
}
// Include config file
require_once "config.php";
// Define variables and initialize with empty values
$new_password = $confirm_password = "";
$new_password_err = $confirm_password_err = "";
// Processing form data when form is submitted
if($_SERVER["REQUEST_METHOD"] == "POST"){
// Validate new password
if(empty(trim($_POST["new_password"]))){
$new_password_err = "Please enter the new password.";
} elseif(strlen(trim($_POST["new_password"])) < 6){
$new_password_err = "Password must have atleast 6 characters.";
} else{
$new_password = trim($_POST["new_password"]);
}
// Validate confirm password
if(empty(trim($_POST["confirm_password"]))){
$confirm_password_err = "Please confirm the password.";
} else{
$confirm_password = trim($_POST["confirm_password"]);
if(empty($new_password_err) && ($new_password != $confirm_password)){
$confirm_password_err = "Password did not match.";
}
}
// Check input errors before updating the database
if(empty($new_password_err) && empty($confirm_password_err)){
// Prepare an update statement
$sql = "UPDATE User_Accounts_ SET password = ? WHERE username = ?";
if($stmt = mysqli_prepare($link, $sql)){
// Bind variables to the prepared statement as parameters
mysqli_stmt_bind_param($stmt, "ss", $param_password, $username);
// Set parameters
$param_password = password_hash($new_password, PASSWORD_DEFAULT);
$username = $_POST['username'];
// Attempt to execute the prepared statement
if(mysqli_stmt_execute($stmt)){
// Password updated successfully. Destroy the session, and redirect to login page
session_destroy();
header("location: login.php");
exit();
} else{
echo "Oops! Something went wrong. Please try again later.";
}
// Close statement
mysqli_stmt_close($stmt);
}
}
// Close connection
mysqli_close($link);
}
?>

Similar TutorialsI have a login system Username and Password.
My password is encrypted with bcrypt, if it okay to store that bcrypt in a session as $_SESSION["hash"]
To verify that the user is who they say they are?
Or do i only need to do
$_SESSION["username"]
Hi,
Recently I've been trying writing a safe password hash and I wanted to know that if I use an MD5 hash at the end, just so it will be like some short of "packed",so instead of saving a 128 string, I'll use md5 to "pack" it into 32 characters and save up to 96 characters.
I know MD5 isn't safe and all, but the question is, does it lower the security ?
Also, would be happy for feedbacks about my password hash
function hash_($input,$key) {
$op=hash("whirlpool",hash("sha512",$key) . "$" . $input . "$" . hash("sha512",$key));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.

Alright, I have created a hash password checker and here is my code: include("include.php"); // include the mySQL info! $users = mysql_query(" SELECT * FROM User "); // Select all from the users table in the database! while($row = mysql_fetch_array($users)) // While it fetches the users do the following... { if (hash("sha256", $password) == $row["Password"]) echo "Congratulations! The Hash matches the password entered into the database!"; } elseif (hash("sha256", $password) != $row["Password"]) { echo "Your Hash failed to match the password entered!"; } Now for some reason this displays a totally blank page. When I turn error display on I get the error "Unexpected T_ELSEIF" on this line elseif (hash("sha256", $password) != $row["Password"]) Any help is appreciated... Hi, I am limbo with this one. What I have makes sense to me, but I know I'm missing something or doing something wrong I have been able to hash passwords with salt by new people registering to my site by doing this: if(!$error) { $alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcedfghijklmnopqrstuvwxyz1234567890"; $rand = str_shuffle($alpha); $salt = substr($rand,0,40); $hashed_password = sha1($salt . $_POST['password']); $query = "INSERT INTO `cysticUsers` ( `FirstName`, `LastName`, `Email`, `Password`, `salt`, `RelationshipToCF`, `State`, `Gender`, `Birthday`, `Status` )VALUES( '" . mysql_real_escape_string($_POST['firstName']) .

Hello PhP Freaks forum In the past weeks ive been trying to make a website, where you can register. Everything seems to work except my cherished Change password feature. Everytime you try to change the password, it just resets it to nothing. Here is the code below. <?php if(isset($_SESSION['username'])) { $username = $_SESSION['username']; $lastname = $_SESSION['lastname']; $firstname = $_SESSION['firstname']; $email = $_SESSION['email']; echo " <h4>Options for:</h4> $username <br /> <br /> First name: $firstname <br />Last name: $lastname <br /><br /><h3>Want to change your password:</h3><br /> <form action='?do=option' method='post'> Old password <input type='password' placeholder='Has to be between 5-15 digits' name='password' size='30' value='' /><br /> <br /> New Password<input type='password' placeholder='Has to be between 5-15 digits' name='newpass' size='30' value='' /><br /> <br /> Confirm new password <input type='password' placeholder='Has to be between 5-15 digits' name='passconf' size='30' value='' /><br /> <center></div><input type='submit' value='Submit'/></center></form>"; }else{ echo 'Please login to view your options!'; } $password = $_REQUEST['password']; $pass_conf = $_REQUEST['newpass']; $email = $_REQUEST['passconf']; $connect = mysql_connect("Host", "User", "Password"); if(!$connect){ die(mysql_error()); } //Selecting database $select_db = mysql_select_db("My Database", $connect); if(!$select_db){ die(mysql_error()); } //Find if entered data is correct $result = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'"); $row = mysql_fetch_array($result); $id = $row['id']; mysql_query("UPDATE users SET password='$newpass' WHERE username='$user'") ?> And i do know that i dont have a if(Empty($newpass)){ Die(Please fill out the new password) } Or any security on the others, but the problem just seems that it resets the password into nothing Hope i can get this fixed Best Regards William Pfaffe This topic has been moved to Application Design. http://www.phpfreaks.com/forums/index.php?topic=353345.0 <?php

I encrypt user password by SHA('$Password') method but now i want to add "Forget Password Module" for which I need to decrypt it first before tell my user but I don't Know how to decrypt it. Please help me........ Guys, Having a major headache here. I need to send an enquiry using jquery and php. The user can only send an enquiry if they are logged in - so it's a one click process. On the click (which is an <a> tag) the user's data is retrieved from the database and sent to the company they are enquiring about. When the link is clicked, a jquery popup is shown to notify the user that the enquiry has been sent. This all works. However, currently the enquiry is sent when the page loads and this is what I'm having trouble with. Code: [Select] <a href="#e" onclick="openinfobox('Enquiry Sent', 1)" class="enq"></a>What I want to do is say if the URL contains #e, then send the enquiry, otherwise do nothing. I understand that the # portion of the url cannot be referenced by PHP. How on earth can I run php process to say only run this php process if there is a # in the url? I have a section on my website where the url points to www.example.com/some_page#some_element #some_element is used by javascript to load the element in question into the parent element. However i need pagination done on this loaded element. How should i go about it? would it work? obv i cant use www.example.com/some_page#some_element/page/2. Any tips or advice? Is a hash array the same thing as an associative array? My PHP books make no reference to this, yet I have seen the term referred to. Thanks. Are there any PHP hashes that are extremely secure and that CANNOT be reverse-engineered?
Hi SMF forum use semi-colom in url for example http://www.phpfreaks.com/forums/profile/?area=showposts;u=71740 after showposts there is semi-colon.

HI, I have a registration script where a password is made with one hash, and a user password reset page that uses another hash. I don't know how to make them the same, as every time I change them, it messes up the code and I get errors. I will comment the parts that I think need changing. Because when I try to log in with the new password that was made by the reset password script, it says "wrong username or password" because either it wasn't updated in the database, or it was updated in a bad way. Any help greatly appreciated. The password email reset code: Code: [Select] <?php define('IN_SCRIPT', true); // Start a session session_start(); ini_set ("display_errors", "1"); error_reporting(E_ALL); $host = ""; $database = ""; $username = ""; $password = ""; $tbl_name = ""; $conn = mysql_connect($host, $username, $password) or die("Could not connect: " . mysql_error()); if($conn) { mysql_select_db($database); echo "connected to database!!"; } else { echo "failed to select database"; } //this function will display error messages in alert boxes, used for login forms so if a field is invalid it will still keep the info //use error('foobar'); function error($msg) { ?> <html> <head> <script language="JavaScript"> <!-- alert("<?=$msg?>"); history.back(); //--> </script> </head> <body> </body> </html> <? exit; } //This functions checks and makes sure the email address that is being added to database is valid in format. function check_email_address($email) { // First, we check that there's one @ symbol, and that the lengths are right if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email)) { // Email invalid because wrong number of characters in one section, or wrong number of @ symbols. return false; } // Split it into sections to make life easier $email_array = explode("@", $email); $local_array = explode(".", $email_array[0]); for ($i = 0; $i < sizeof($local_array); $i++) { if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i])) { return false; } } if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1])) { // Check if domain is IP.

How do I accomplish this. The url looks like: http://www.somesite.com/findagent/MapController.aspx?action=getAgentsByRadius&distance=5&filter=PL&sessionhash=%3F%01j%23%3Eo%0AH%05h%0B%3FU%0B%3F%3F%3F%7B%3F%3C&zip=91111 I guess getting the session id and urlencoding on my end wouldnt work? I would have to grab their session id and encode somehow? What is the difference between the hash algo "tiger192,3" and "tiger192,4"? I ran fsum/HashCalc to get a TIGER hash from a string and it is different with either "tiger192,3" or "tiger192,4". I also tried using the hash as hex string input to rehash 3 or 4 times, but still cannot get an equivalent to that of "tiger192,3" or "tiger192,4"... |
