PHP - Better Password Protected Pages / Login Form .. ??
Hello:
I wanted to see if I can make my password protected pages in my admin area, and the login form "more secure." I was told I should use MD5 / SALTING / HASHING to do this. I have tried some online tutorials, but am not understanding it, so I wanted to start from what I have and build upon it> This is my database table storing the myAdmins data (when I initially insert it into the database): Code: [Select] CREATE TABLE `myAdmins` ( `id` int(4) NOT NULL auto_increment, `myUserName` varchar(65) NOT NULL default '', `myPassword` varchar(65) NOT NULL default '', PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8; INSERT INTO myAdmins VALUES("1","abc","123"); This is the login form I use: Code: [Select] <?php include('../include/myConn.php'); include('include/myAdminNav.php'); session_start(); session_destroy(); $message=""; $Login=$_POST['Login']; if($Login){ $myUserName=$_POST['myUserName']; $myPassword=$_POST['myPassword']; $result=mysql_query("select * from myAdmins where myUserName='$myUserName' and myPassword='$myPassword'"); if(mysql_num_rows($result)!='0'){ session_register("myUserName"); header("location:a_Home.php"); exit; }else{ $message="<div class=\"myAdminLoginError\">Incorrect Username or Password</div>"; } } ?> <form id="form1" name="form1" method="post" action="<? echo $PHP_SELF; ?>"> <? echo $message; ?> Username: <input name="myUserName" type="text" id="myUserName" size="40" /> Password: <input name="myPassword" type="password" id="myPassword" size="40" /> <input name="Login" type="submit" id="Login" value="Login" /> </form> This is the code on top of each page I password protect: Code: [Select] <? session_start(); if(!session_is_registered(myUserName)){ header("location:Login.php"); } ?> Works well, but can it be "better"?? And, if I am allowing the admin to update his/her username or password, I do it this way: Code: [Select] <?php include('../include/myConn.php'); include('include/myCheckLogin.php'); if ($_SERVER['REQUEST_METHOD'] == 'POST') { $myUserName = mysql_real_escape_string($_POST['myUserName']); $myPassword = mysql_real_escape_string($_POST['myPassword']); $sql = " UPDATE myAdmins SET myUserName = '$myUserName', myPassword = '$myPassword' "; mysql_query($sql) && mysql_affected_rows() ?> <?php } $query=mysql_query("SELECT * FROM myAdmins") or die("Could not get data from db: ".mysql_error()); while($result=mysql_fetch_array($query)) { $myUserName=$result['myUserName']; $myPassword=$result['myPassword']; } ?> <form method="post" action="<?php echo $PHP_SELF;?>"> <input type="hidden" name="POSTBACK" value="EDIT"> Username: <input type="text" size="60" maxlength="60" name="myUserName" value="<?php echo $myUserName; ?>"> Password: <input type="password" size="60" maxlength="60" name="myPassword" value="<?php echo $myPassword; ?>"> <input type="submit" value="Submit" /> </form> Should it be "better" .. ?? I don't seem to understand how to "encrypt" all of this to make it "stronger" .. Ideas? Improvements? Similar TutorialsHello everyone: I wanted to see how I can make a simple login page (user name and password) that redirects to a page(s) if the login is correct. Also, I wanted to put protection on the page(s) that will send the user back to the login page if the credentials are nor correct. I would imagine the username/password would be stored in a database table (Admins), and the correct login info would be stored in a session ..? I am use to doing this with ASP, but never PHP. I want to make sure I understand how to do this properly and securely so I can use this as a model for other systems. In ASP I would do a protected page like this: a_login_check.asp Code: [Select] <% if session("admin_user_name") = "" then session.abandon response.redirect "login.asp" end if %> Protected-Page.asp Code: [Select] <!-- #include file="include/a_check_login.asp" --> <html> ... CONTENT ... </html> And of course there is the login page itself ... (I thought it would be nice to add a "Forgot Password" link on the login page, but if that is too complicated I can do that later .. or is it easy ??) Anyway, can someone point-out to me how to do this. I would appreciate it! Hi, I have built a registration and login system for a website, part of which I wish to protect certain pages. The registration systems works well, as does the login BUT I am having difficulty with the next stage. How do I then 'capture' the username and password that were entered by the user and get the PHP page I want to protect to check that these are valid? I guess it is a piece of code I need to put in the top of the protected page? Here is the final piece of code (which then includes a link to the page I want to protect) from the login page which includes session_register, but then how can I use this information in the page I wish to protect? //Now if everything is correct let's finish his/her/its login session_register("username", $username); session_register("password", $password); echo "Welcome, ".$username." please continue onto our ".$sub." membership area...<a href=".$index.">click here</a>"; } Thanks, Simon I have developed a code for a login and seems to work well (No syntax error according to https://phpcodechecker.com/ but when I enter a username and a password in the login form, I get an error HTTP 500. I think that everything is ok in the code but obviously there is something that I am not thinking about. The code (excluding db connection): $id="''"; $username = $_POST['username']; $password = md5($_POST['password']); $func = "SELECT contrasena FROM users WHERE username='$username'"; $realpassask = $conn->query($func); $realpassaskres = $realpassask->fetch_assoc(); $realpass= $realpassaskres[contrasena]; $func2 = "SELECT bloqueado FROM users WHERE username='$username'"; $blockedask = $conn->query($func2); $blockedres = $blockedask->fetch_assoc(); $bloqueado = $blockedres[bloqueado];
//Login if(!empty($username)) { // Check the email with database I'm not sure if this is a php or Apache question but here goes anyways. I have my Apache web server set up so I can access it from anywhere which obviously means anyone else can access it too. I have my index page which is basically a menu for the site password protected with a simple php script. The problem is the index.php password page can be bypassed by just typing the name or path of any of the pages on the site. I don't want to have to password protect or enter a session variable onto every page. Is there a practical way to make it where no page can be accessed without being routed from the index.php page ? Hi, I have the following code: Code: [Select] <?php $cmd = $_GET['cmd']; if($cmd=="") { $cmd = "adminlogin";} // This creates the header for each of the installation pages switch($cmd) { // This is the installation agreement page case "adminlogin": print <<<LOGIN <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Member Site Maker 1.0</title> <link rel="stylesheet" href="style.css" type="text/css" /> </head> <body> <div id="head" align="center"> <h1 id="siteName">Member Site Maker </h1> <br /> <table align="center" border="0" bgcolor="#CCCCCC"> <tr> <td align="center"><span class=style1><b>ADMIN LOGIN</b></span></td> </tr> <tr> <td> <form action=admin.php?cmd=manage method=POST> Password: <input type=text name=password1> </td> </tr> <tr> <td> <input type=submit name=submit value=Submit> </td> </tr> </table> </form> LOGIN; break; // Managing Users case "manage": include_once("header.html"); include_once("data/password.php"); $password1 = $_POST['password1']; $password2 = base64_decode($password); if ($password1 != $password2) { print <<<BADLOGIN <table width=953 border=1 align=center bgcolor=#00CCFF> <tr> <td><span class=style1><b><center>Failed Login</center></b></span></td> </tr> <tr> <td><span class=style2>Your passwords do not match.

However this does not stop someone typing http://www.mysite.com/folder/admin.php?cmd=dashboard If they do that, it skips the password form and password check, and they can then go ahead and do whatever in the admin.php file. How can I prevent this, so that a password check is automatically done before allowing somebody to view the page? I have tried adding the code I used in the manage section, but it doesnt work again. Any help will be greatly appreciated, I been trying to work it out all day and run out of ideas. Many Thanks I have a register page that MD5 Hash's the users password and a login which also does this. However, no matter what I try it always says incorrect password. Even when I remove the MD5.

I have been reading in almost everywhere that we should not use our own custom login and password validations ( like regex etc.) but instead use the filter_var and filter_input built in functions provided by PHP 5 and above. However even after searching for more than an hour for with different search strings, I have not found even a single example that shows how we may validate for a username/login and password in a login form. Can someone be kind enough to provide a strong secure validations for username and login.
Additionally I would also like to clarify if the username and login fields in a Login form be manipulated in any manner to pose a security threat? I mean can a hacker craft a username/login or password in such a manner as to pose an injection or any other threat?
Thanks all.
Hi. I have made a login script, but I would wan't to encrypt the password. I followed a tutorial and got this: login.php <?php $password = "secret"; echo $password; /* displays secret */ $password = sha1($password); echo $password; /* displays e5e9fa1ba31ecd1ae84f75caaa474f3a663f05f4 */ ?> <form action="validate.php" method="post"> <label for="username">Username</label> <input type="text" name="username" id="username" /> <br /> <label for="password">Password</label> <input type="password" name="password" id="password" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> <?php ?> validate.php <?php include "setup.php"; /* get the incoming ID and password hash */ $username=$_POST['username']; $password=$_POST['password']; $password=md5($password); // Encrypted Password /* establish a connection with the database */ $server = mysql_connect("$db_host", "$db_username","$db_password"); if (!$server) die(mysql_error()); mysql_select_db("$database"); /* SQL statement to query the database */ $query = "SELECT * FROM users WHERE Username = '$username' AND Password = '$password'"; /* query the database */ $result = mysql_query($query); /* Allow access if a matching record was found, else deny access. */ if (mysql_fetch_row($result)) echo "Access Granted: Welcome, $username!"; else echo "Access Denied: Invalid Credentials."; mysql_close($server); ?> Its the line $password=md5($password); // Encrypted Password that messes everything up. If I delete it and login, everything is fine, if I add it it says Code: [Select] Access Denied: Invalid Credentials I need help with this one! And if someone have time, give me some ideas how to make PHP scripts safer!

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've been assigned a project at work. I did not develop the application and the individual who did used CodeIgnited framework and mysql as the db.
Here's the problem, I'm not given much OT to do this and in our meeting the best way to proceed was to replicate the database for different parts of the organization. Basically we are a subsidiary and have been using an application that other groups within the organization want to use. Usually I would reconfigure the db schema and add org ids and in the user table add the appropriate organization to go to. However, they are not giving me enough time to do that.
So what I'm thinking is to just create a copy of the database we use (just the structure) and create a new database.
What I want to know is how to use mysql to check to see if a user exists in one database and if they don't then to go on to the next database. I understand this is a very sloppy way to do it, but it's the way we are moving forward.
I found the code to connect to the db in CodeIgnitor... how can I connect to a database, check to see if the user exists, then close that db connection and try the next database?
/**
* Select the database
*
* @access private called by the base class
* @return resource
*/
function db_select()
{
return @mysql_select_db($this->database, $this->conn_id);
}
Thanks in advance.
Hi! I have read like crazy to find a tutorial on a login page without My_SQL. Anyway I am working on a easy login/logged out page with sessions. Here is the login page with tree users in an array.
The things that I need some hints to solve is, when clicking on login the error message don't show. Instead the script goes to the logged in page right away. And when you write the wrong password you get loged in anyway.
I am not sure how or if it's possible to write a varible to a file this way. But I tried and recived a parse error with the txt varible.
When searching for topics I get more confused with the My_SQL varibles. I am near a breaking point at cracking the first step on PHP, but need some advice.

Hello Everyone, I recent made a simple membership website. Every page I created works exactly how I envisioned it... All members data from my registration form goes into my database along with their md5 Encrypted passwords with a time-stamp. Subsequent pages have a start_session included. I am very please with it except ONE THING. Logging in is now a problem... username is recognized but NOT the password. Now the strange thing is that when I go into the database and copy the encrypted password and paste it into the password field in my login page, I miraculously get into my website with NO problem. " How do I get the registered members Encrypted Passwords to be recognized by the database when the registered members decide to logging in with the password that they create? " Is there a easy fix for this? I appreciate ALL your help... thanks mrjap1 Hi, I don't know why it outputs" You are now registered BUT the user name and password don't show up in the database! I want to encrypt the passwords so maybe that is problem, I don't know, please read scripts below. here is register.php: ============== Code: [Select] <html> <head></head> <body> <form method="post" action="" > <p>Create a username <input type="text" name="newUsername"/> </p> <p>Create a password <input type="password" name= "newPassword" /> </p> <p> <input type="submit" value="Make account now" name="makeAccountSubmit" /> </p> </form> <?php if(array_key_exists("makeAccountSubmit",$_POST) && !empty($_POST["newUsername"]) && !empty($_POST["newPassword"]) ) { //IF username doesn't exist, then store new user login info to db dummydpevx mysql_connect("localhost","root"); mysql_select_db("someDB"); $newUserName=$_POST["newUsername"]; $newPassword=crypt($_POST["newPassword"]); $usernameQuery=mysql_query("SELECT userName FROM users WHERE userName='$newUserName'"); if(mysql_num_rows($usernameQuery)==0) { $makeNewAccountQuery=mysql_query("INSERT INTO users userName,userPassword VALUES('$newUserName','$newPassword')"); print "You are now registered, <a href='login.php'>proceed to login</a>"; } if(mysql_num_rows($usernameQuery)==1) print "Username taken. Please make another one. <br />"; } here is login.php: ============ Code: [Select] <html> <head></head> <body> <form method="post" action=""> <label>Username:</label> <input type="text" name="username" /> <br /> <label>Password:</label> <input type="password" name="password" /> <p> <input type="submit" value="Login" name="Login" /> <input type="reset" value="Reset" name="Reset" /> </p> </form> <?php if(array_key_exists("Login",$_POST) && !empty($_POST["username"]) && !empty($_POST["password"])) { $attemptedUsername=$_POST["username"]; $attemptedPassword=$_POST["password"]; mysql_connect("localhost","root"); mysql_select_db("someDB"); $getLoginInfoQuery=mysql_query("SELECT userName,userPassword FROM users WHERE userName=$attemptedUsername AND userPassword=$attemptedPassword"); $getLoginInfo=mysql_fetch_assoc($getLoginInfoQuery); $getUsername=$getLoginInfo["userName"]; $getPassword=crypt($getLoginInfo["userPassword"]); if(crypt($attemptedPassword,$getPassword)==$getPassword) { session_start();//NB: Start session BEFORE doing any session stuff! $_SESSION["isAuthenticated"]="userAuthenticated"; header("Location: xmlShredderIndex.php"); exit; } else print "Please register!"; } Also, if any has time, please see my other post, it is straightforward instructions to see if you get same error as me, thanks. http://www.phpfreaks.com/forums/index.php?topic=347639.msg1640652#msg1640652 Any help much appreciated! Hi, Having completed a site migration this am everything went well aside from issues with logging into and out of our site where two files are used and appear as white pages. When logging into our site, proc_login.php is used and when logging out proc_logout.php is used. Both processes result in a white "blank" page instead of the php files forwarding on. I've no idea about php generally and have been trying my best to find useful and similar information online to attempt to resolve the problem. I am now stuck. The site works perfectly on my local web server, and what is really baffling me is the site also works perfectly on Domain B on the exact same server I'm trying to get the site running under as Domain A. In other words as both Domain A & B are configured on the same host server I'm thinking all the inherited php/apache/mysql settings should be identical (or pretty much thereabouts) and therefore am more confused than ever! I simply don't know where to start therefore in resolving this problem. I've tried looking in the error log file and have also played around with turning on error enabling on those specific php files to try and follow any errors, however the "errors" generated are no different than the ones present on sites where the login/logout process works just fine. I've hopefully attached both files and if anyone could assist in helping me narrow down my search for a solution I'd be very appreciative. Thanks. hi i need help an idea how can i separate members from admins since i dont know how to create login form i used tutorial ( http://www.youtube.com/watch?v=4oSCuEtxRK8 ) (its session login form only that i made it work other tutorials wre too old or something) how what i want to do is separate members and admins because admin need more rights to do now i have idea but dont know will it work like that what i want to do is create additional row in table named it flag and create 0 (inactive user) 1 (member) 2 (admin) will that work? and how can i create different navigation bars for users and admins? do you recommend that i use different folders to create it or just script based on session and flag? Hello, I'm working on a register script, and basically I would like the user to repeat their password. And I would like PHP to compare the to passwords, and if they both match then it continues, whereas if they don't match it calls an error. Here is what I have so far: Form: Consists of 2 text fields - subpass, and subconfirmpass PHP: $field = "subpass"; if(!$subpass == $subconfirmpass){ $form->setError($field, "* Passwords do not match"); } $field is referring to the text fields in where the user inputs their password $form is keeping track of errors in user submitted forms and the form field values that were entered correctly. I would appreciate your help, Thanks Hello, My user login script saves their passwords into my SQL in a md5 encryption. I am currently working on a 'forgot password' that sends the password to their email. The code that pulls out the password is this: echo $req_user_info['pass']; Now is there a way to decrypt the 'pass' (currently nothing is displayed - not even the encryption code) Please help - Ollie |
