Python uses Karatsuba multiplication for its long integers. This works very well for not too big long integers but when they get huge using the GMPy module is much quicker. If you want to see a practical demo of that when calculating pi see

chroot is a layer in the security onion. Like every other layer it adds security but isn't perfect. Security will never be 100%. If you want more security, then likely you want another layer in the onion.
