I've just implemented PHPass into an application that I am working on, and I am seeing a strange inconsistency. The issue is, the application is installed on one site, and it works perfectly. But the same application works on another site, and the login nor registration works. Does anyone know what might be the issue that registration and login works on one site but not the other with PHPass? Thanks. Hi, My hosting company (Bluehost) told me when someone goes to my home page, it sends these series of queries and this is the reason for my high cpu usage and this is why my site says Error Establishing Database. The hosting company gave me these: Each script is using a decent about of CPU. [2:09:33 AM] hollane3 31881 6.2 0.1 186084 49000 ?

I have a question regarding PHP sessions and their security. So here is my story ... I created a login script (login.php) for my website. When a user goes to the login.php page, they see a login form that they must fill with their username and password to login to the members' area and view their profile, etc. On that login page, when the user enters their username and password and then clicks the "Login" button, my script filters the data, sends MySQL query and checks if the login is valid. If the login is NOT valid, then they get a "Login Failed" message. If the login is valid, I register their username and the password in sessions and redirect them to the members.php page. Here is some of my code for my login.php page after mysql confirms the login is valid <?php $query = mysql_query('SELECT * FROM `users` WHERE username='$user' AND password='$pass'"); $numRows = mysql_num_rows($query); if ( $numRows ) { // login is valid $_SESSION['username'] = $user; $_SESSION['pass'] = $pass; // redirect user to members area header('Location: /members.php'); } else { // login is invalid echo "Login failed"; } ?> My question is ... is this login script secured? I mean, I am not generating any session id or any cookie. I am just storing the username and the password in two session variables and those are the things that i will use to display the user's profile, etc. Can attackers attack this script? Is this secured or is there any other way I can make it stronger? |
