I have changed the password using grocerycrud encryption callbacks but when i tried to login with same password it says wrong password. please tell me how use encryption in login model.
this is my login model.
function check_user($username, $password) {
$this->db->select('*'); //select all
$this->db->from('users'); // table name
$this->db->where('username', $username); // where username is equal to $username
$this->db->where('password', sha1($password)); // and password is equal to $password
$query = $this->db->get(); //get data from DB
return $query;
}
