Password hashing

@Narf
Thanks for useful explaining.

With your explaining and other friends, I've change my code:

PHP Code:

$username = $this->input->post('username');
$password = $this->input->post('password');
                
$password_hashed = $this->user->get_one_by(array('USER_NAME' => $username))->PASSWORD;
var_dump($password_hashed);

var_dump(password_verify($password, $password_hashed)); 


And the result is

Code:

string(45) "$2y$10$B7uJAngw0wtDtncMpsOfvetyFCg//VqdnqjdEZ" bool(false)

My entry password is "zz" which is during registering changed to hash and then saved in the DB.

My password in the db is

Code:

$2y$10$B7uJAngw0wtDtncMpsOfvetyFCg//VqdnqjdEZ

My get_one_by() function is in my model:

PHP Code:

function get_one_by($cond = array())
{
    $result = $this->db->get_where($this->tablename, $cond);
    if ($result->num_rows()) return $result->row();
        
} 


the password_verify() always is FALSE !
