Answer 1

Ok I made this work with password_verify()

$usuario = $_POST["Nick"];
$contra = $_POST["Pass"];   
$stmt = $conn->prepare("SELECT Nick, Password FROM usuario WHERE Nick = ?");
$stmt->bind_param( "s", $usuario); 
$stmt->execute();
$stmt->store_result(); 
$stmt->bind_result($a, $b);   

if($stmt->fetch() == 0){ 
    header("Location: ../Entrar.php?message=Error");
    exit();
}
else {  
    if(password_verify($contra, $b)) {
        session_start(); 
        $_SESSION['Usuario'] = $a; 
        $_SESSION['estado'] = 'Autenticado';  
        header("Location: ../../Index.php"); 
        exit; 
    }
    else{ 
        header("Location: ../Entrar.php?message=Error");
        exit;
    }
}
