Hi, all I was trying to add md5 encryption to all of my scripts that
needed username and password info entered into the db well every thing
goes smoothly until I try and login.

I encrypt it when it goes in and before I check it after I sent the
login information I encrypted it again but yet it still will not check
right it wont veryify that the information is fright for instance.

<?

//////// login example ////////

Include ("config.php');

$user = $_POST["user"];

$pass = $_POST["pass"];

$pass = md5($pass);

$login = mysql_query("SELECT * FROM admin_guestbook WHERE
username='$user' AND password='$pass'");

$login_check = mysql_num_rows($login);

if($login_check > 0){

session_register('user');

$_SESSION['user'] = $user;

session_register('password');

$_SESSION['pass'] = $pass;

header ("Location:admin_page.php");

}

else {

print "You are not logged in You entered the wrong username
and password combination please try again";

include "admin.php";

}

?> and when I run the check it wont login

Re: MD5 encryption problems

I assume the form has attribute method="post" and not method="get"
other than that I would say that it should work assuming you give the
correct password. You do realise that you have made the passwords case
sensitive I assume. Perhaps the conversion from non-md5'd passwords to
md5 passwords went wrong?

Also, put a die() after header, in case it ever goes wrong, and you put
more code at the bottom of the page.

Re: MD5 encryption problems

Well what happens is it doesn't really show any errors it just goes
straight to the username is invalid and the info is 100% correct.
