jak usunąć salt + sh1, Chciał bym stworzyć proste logowanie Opcje

[lipek80]

Witam

Chciał bym się pozbyć zabezpieczenia salt z poniższego kodu. Chciał bym, aby można było się zalogować na stronie za pośrednictwem hasła które jest zapisane w bazie danych. Nie musi być zakodowane.

do bazy danych wpisałem

w pole haslo

"twoje_haslo"

plik salt.php wygląda tak jak poniżej

<?php
 
function salt($password) {
 
	$salt = '9237356b46c0f53f71eb189b95c40ed1fa25a685';
 
	return sha1(sha1($password) . $salt);
}
 
 
?>

I niestety to nie działa.

Stworzyłem plik log.php

[PHP] pobierz, plaintext 
<?php
 
	include(dirname(__FILE__) . '/../salt/salt.php');
    echo salt('twoje_haslo');
 
	?>
