Question

I wanna save hashed password in mysql database,so I develop following method in CodeIgniter.

private function hashing($password = '',$mail = '')
{
    $hashcode = md5($password, $mail);
    return sha1($hashcode,md5($hashcode.$mail));
}

for insert:

$data = array('mail'=>$mail,'password'=>$password,'actived'=>1,'time'=>time());
$this->db->insert('users', $data);

other field inserted correctly instead password.

it will generate something like

òLmy­ÉZÔe+ú§3GèÇu‘

it can’t be saved in mysql database.where is the problem?

edit database Collation is utf8_unicode_ci
edit I’m using CodeIgniter,so it doesn’t need mysql_real_…

You probably meant to do this:

return sha1($hashcode . md5($hashcode.$mail));

Instead of this:

return sha1($hashcode,md5($hashcode.$mail));

The second argument to sha1() is a boolean value, controlling whether it returns the hash in raw or string format (false = string, which is what you want to insert).
