893 Rijndael appears to be consistently a very good performer in
894 both hardware and software across a wide range of computing
895 environments regardless of its use in feedback or non-feedback
896 modes. Its key setup time is excellent, and its key agility is
897 good. Rijndael's very low memory requirements make it very well
898 suited for restricted-space environments, in which it also
899 demonstrates excellent performance. Rijndael's operations are
900 among the easiest to defend against power and timing attacks.
