Improving My Registration Form

Hi, I have a registration and i wish to improve the security somewhat.

 

I want to be able to have an email sent to the user that has registered which will consist of his/her;

 

Name

Username

Password???

and some form of Security Code

 

I was wondering how I should go about doing the security code, since the code will be stored in the database.

When the user clicks on a link in the email they would be directed to a page where they enter their username and security code, and the processing script would then compare them, and either allow access or deny it.

 

I was thinking something like sha1, md5, etc... Any help with this would be greatly appreciated ^_^

my suggestion is:

  • user enters username / password and email address into form.
  • data gets saved into user table, along with an md5 hash of the username, email and a salt word
  • the user is emailed a link with the md5hash as a variable in the link
  • this redirects the user to the login page, with a couple of flags to show they are confirming,
  • when they hi t submit you check the md5 matches the one in the db and activate the account

sorry, im afraid i might not have explained properly. the email will contain a link with the hash in it|:

example:

thank you for registering with............

please click on the link below to confirm your registration:

 

http://somesitesomewhere.com/confirm.php?q=2df352fd23fd62fd72fd72fd72ff387d736251fdeez

 

where q is the md5 of their name and email address.

 

this hash will be unque to their account. you done md5 the email at all

Okay - I can't seem to be able to get the hang on the md5 hash as a code for the confirmation. So, I thought - how difficult would it be to have some code that generates a random (preferrably unique) number that is then inserted into the database and used as that person's personal confirmation code?

$usersEmailAddress = [email protected];
$usersPassword = '123456';
$salt = 'wibbleotter'; // this is secret to you.
$token = md5($usersEmailAddress.$usersPassword.$salt);
$query = "INSERT INTO User_table .... "; // insert your users details and the token.
$url = "http://mysite.com/confirm.php?q=$token";
// email the above to the user and when they cliick on it to log in
check with a query like this
$query = "SELECT id FROM User_table where username =$username AND password = $password AND token = $token";

 

hope that help explain it a bit better

Don't use the password in the hash, especially not when you use MD5; It's a BAD idea. Use unique_id (), as Jessica linked to (and you so correctly guessed would be better).

Also, don't send the password in the e-mail; E-mails are sent as plain text, and can quite easily be intercepted. Remembering the password is the user's responsibility, after all.

Sorry John but that doesn't appear to help much.

 

I did however search google and found on php.net a function could "rand();" however I didn't see any way in which i could make it unique. Any ideas?

 

sorry about that try to use this one

 

<?php

 

printf("uniqid(): %s\r\n", uniqid());

 

?>

Okay lol. (Sorry for the code being long - I think they can be tidied up a bit but that will have to come later when there is some kind of function to the forum).

 

Registration Form:

 


<?php

if($_POST["submitReg"]){
$regName = $_POST["name"];
$regUsername = $_POST["username"];
$regPassword = $_POST["password"];
$regREpassword = $_POST["rePassword"];
$email = $_POST["email"];

if(empty($regName) && empty($regUsername) && empty($regPassword) && empty($regREpassword)){
$msg3 = "The form was submitted empty.";
}else{
if(empty($regName)){
$msg3 .= "The name field was empty.";
}else{
if(empty($email)){
$msg3 .= "The email field was empty.";
}else{
if(preg_match("^[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$", $_POST["email"]) === 0){
$msg3 .= "Please enter a valid email.";
}else{
if(empty($regUsername)){
$msg3 .= "The username field was empty.";
}else{
if(empty($regPassword)){
$msg3 .= "The password field was empty.";
}else{
if(empty($regREpassword)){
$msg3 .= "The repeat password field was empty.";
}else{
if($regPassword != $regREpassword OR $regREpassword != $regPassword){
$msg3 .= "The password fields didn't match.";
}else{
$check = select("*", "members", "username = '$regUsername'");
$assoc = mysql_fetch_assoc($check);

if($regUsername == $assoc["username"]){
$msg3 .= "That username has been taken, pick another.";
}else{

Make sure you filter that, the way you seem to be inputting is vulnerable to sql injection
