Same Hash value on different input

Question

I have got this html form:

 <form action="seite2.php" method="post"> Benutzername:<br /> <input type="Text" name="username"><br /><br /> Passwort:<br /> <input type="Password" name="passwort" /> <input type="Submit" value="Absenden" /> </form> 

on seite2.php I have got this code first, to check the Hash value:

$username = $_POST["username"];
$passwort = $_POST["passwort"];

$pass = sha1($passwort);

echo $pass;

then, I want to check wether username&&password is correct and compare the hashs. Lets say username is: mue. and password is: pass. I get this hash: da39a3ee5e6b4b0d3255bfef95601890afd80709.

if($username == "mue" AND $pass=="da39a3ee5e6b4b0d3255bfef95601890afd80709")
{
    echo '<p>';
    echo "Herzlich Willkommen";
    echo '</p>';
}
else
{
    echo '<p>';
    echo "Login failed";
    echo '</p>';

But in my Browser, I get following response: da39a3ee5e6b4b0d3255bfef95601890afd80709 Login failed.

And no matter which user or password I'll take, the hash given back from the browser is always the same.

Answer 1

The code is ok,i try it and work but the sha1 of "pass" is:

maybe you modify the worse file. see your editor and see if you change the right "seite2.php". if you change the path location of this file maybe the old file remained in the IDE and you edit this one and no the new one.
